Elegoo saturn review

Elegoo saturn review DEFAULT

I’ve reviewed a couple of consumer 3D printers from ELEGOO so far…the Mars Pro MSLA printer, and the Neptune 2 FDM printer. Now I’m taking a look at the Mars’ big brother, the ELEGOO Saturn MSLA printer.

SLA vs FDM: The Two Types of 3D Printing

Briefly, for our readers who aren’t that familiar with 3D printers but are thinking about dipping their toes in the water:

There are essentially two types of printers available, stereolithographic (SLA) and fused deposition modeling (FDM). FDM models use a heated filament (most frequently PLA plastic) to build up a model, adding layer after layer until the model is complete. SLA printers use light to solidify a layer of resin at a time, creating the model. In the case of the Mars Pro, which is a masked stereolithographic (MSLA) printer, it uses light specifically from an LED array combined with an LCD photomask.

Both types of printers use their own type of “slicer” software to prepare a 3D model for printing, allowing you to adjust for the type of material you’re printing, how much detail you want to put into the final product (the finer detail, the longer it takes to print), and if you need to add any “supports” into the model to help ensure that the model doesn’t break or deform during the printing the process.

If you’re new to 3D printing, this can all seem a bit overwhelming. Don’t worry, I’ll be explaining more as I describe my experiences with the Mars Pro. In the meantime, think about it this way: SLA printers like the Mars Pro and Saturn are best if you want to print smoother, more detailed figures such as tabletop miniatures for Dungeons & Dragons, while FDM printers excel at printing larger, less detailed parts and objects, such as cosplay armor pieces and weapons.

What Is the ELEGOO Saturn?

The ELEGOO Saturn uses an 8.9 inch 4K LCD screen for both higher resolution and faster layer curing times. Additionally, it has a significantly larger build area than the Mars Pro, with a build volume of 7.55 x 4.72 x 7.87 in.

Unboxing the ELEGOO Saturn

I raved about how well packaged the ELEGOO Mars Pro was in my review, and if anything, the Saturn is packaged just slightly better. ELEGOO has included plastic interior corner protectors and hard cardboard edges around all that foam, ensuring that your printer arrives in good shape.

Removing the top protective layer will reveal the ELEGOO Saturn, nestled in even more foam. I was pleasantly surprised to discover that ELEGOO had branded the plastic cover of the printer!

Even more foam in the plastic case protects the z-axis drive shaft, and also contains both the resin tank and the build plate.

Removing the tool kit box from the case, it’s a quick job to get the printer set up. Many of the same tools are included here as were with the Mars Pro(though the box of nitrile gloves in the picture are mine).

Adventures in 3D Printing With the Saturn

Once I had removed the protective plastic coverings on the LCD and FEP film, it was time to get to the most important preliminary step: leveling the printer. As opposed to leveling an FDM printer, this is a fairly easy process. I loved that ELEGOO included a leveling paper made of thin card with the Saturn. Not only is it the perfect thickness, but it also included the leveling instructions right on the card:

Included with the printer on the USB drive are some demo models, including the ELEGOO rook that came with the Mars Pro. I decided I would start with that one, just to provide a baseline(and a good performance comparison with the Mars Pro). My first step(as should yours be) was to set up a profile for the Saturn in Chitubox, the 3D slicing software for MSLA printing. The second step was to enter the information for the type of resin I was using. I thought it would be fun to do some prints using Elegoo water washable clear blue resin. Different resins have different optimal curing times for both the base layer(for good adhesion to the build plate) and subsequent layers. With a little searching on the web, I was able to find a good guide to the different ELEGOO resins. I then imported the rook model into Chitubox, and sliced it using the settings both for the Saturn and the clear blue resin.

It was then time to get to printing. I filled up the resin tank about a third full as recommended by the instructions, plugged in the USB drive, and selected the rook model from the print menu. At that point, the printer got to work.

I should mention that, while the Saturn is generally a fast printer, the clear blue resin takes a lot longer to cure than non-transparent resins. So I wasn’t really getting an accurate speed comparison between this printer and the Mars Pro. But then again, if you need proof that the Saturn is a faster printer, you can easily find benchmark results from serious 3D printing sources. And so, a little over 7 hours later:

As you can see, the rook adhered well to the build plate…perhaps a bit too well. It was a challenge to remove, and I unfortunately did a little bit of damage to the base in trying to pop it off the plate using the metal scraper. This was still preferable to the print not sticking to the plate, which would result in a failed print, and could potentially damage the FEP film.

After finally freeing the rook from the build plate, I went through standard cleanup. First, a wash with water(as it’s water washable resin) and then, after it had dried, a few minutes under a UV lamp to cure the resin.

I liked the look of the resin and the general level of detail, so thought I’d move on to a different print. For the next model, I chose to go with a holiday ornament from the Fates End 2 Kickstarter, which I’d written about earlier this year.

This print took a bit longer than the rook, clocking in at approximately 10 hours. Much like the rook, though, the print was stuck fast to the build plate. Wanting to get it free without damaging it, I again took to the Web to see what advice I could find to remove the model.

I decided to try a method known as temperature shock. After cleaning off any remaining liquid resin I could from the build plate and model, I put the build plate(with model still attached) into the freezer for about 15 minutes. Removing it, I then ran it under warm water. This caused the resin to contract slightly, allowing me to pop it off the plate with ease.

I was very impressed with how the details on the model turned out, especially the fins on the dragon heads. I posted a picture of the model on Facebook and my sister even demanded I give it to her!

Having successfully printed up these two models, I decided it was time to really put the Saturn to the test. I was going to print something that not only took advantage of the larger build volume of the printer, but would(if successful) demonstrate the capabilities of the ELEGOO Saturn. And so, I grabbed the free Notre Dame Cathedral model from MyMiniFactory.

This would also prove to be a long printing process. After slicing the 3D model, there was an estimated print time of 15 hours. Making sure that I added plenty of resin in the tank, it was time to really test out the Saturn.

As you can see from that tank, I almost didn’t have enough resin to finish…the level is pretty low. But finish it did, with astonishing detail. Sadly, my washing and curing station wasn’t big enough to handle a model this big. ELEGOO has the Mercury X Wash and Cure machines on preorder currently, which can accommodate the large prints from the Saturn. But for now, I had to rely on using some plastic tubs to wash the model, and then cured it using UV directly from the sun.

ELEGOO Saturn: The Verdict

I referred to the ELEGOO Saturn at the start of this review as the big brother to the Mars, and that’s true in a couple of ways. The first is the most literal: The Saturn has a print resolution of 3840×2400 versus the Mars’ 2560×1440, with a build size of 7.55″ length x 4.72″ width x 7.87″ height versus the Mars’ 4.53″ x 2.56″ x 5.9″. Which means everything is bigger:

Size isn’t the only difference between the printers, though. The level of detail that you can achieve with the Saturn is much higher than with the Mars Pro, and when printing the same model with the same resin, the Saturn is also faster.

And while this won’t be an issue for all, the Saturn also includes a network port, so that you can print from your computer. The Mars Pro can only print via its USB port.

I’ve found my time so far with the ELEGOO Saturn to be a fantastic experience. I was blown away by the level of detail I was able to achieve. It’s also a very easy machine to use, much like the Mars Pro. MSLA resin printing is a process that’s fairly easy to do, but has a lot of cleanup afterwards. As most of you are aware, liquid resin can irritate your lungs and your skin, which is the reason for the included face masks and gloves. Plus you have to wash and cure the resin, extra steps that are unnecessary with FDM printing. But the results speak for themselves.

Despite the ease of working with the Saturn, it also served as a reminder that 3D printing is still a hobby. We’re not yet at the point where you can take a printer out of its box, plug it in and start churning out amazing pieces. To get the best results, you need to turn to other hobbyists, like I did, to figure things out like the best way to get prints off the build plate without damaging the print. But if you’re looking for a great printer to take that hobby journey with, the ELEGOO Saturn definitely fits that bill.

The ELEGOO Saturn retails for $500. As of this writing, they’re unfortunately sold out at the ELEGOO store on Amazon(Update 6/17: They’re back in stock on Amazon at $499.99!). If you’re interested in getting a Saturn, keep your eyes open for future restocks as ELEGOO tries to ship Amazon more units as often as possible. Or, if you don’t need a printer as large as the Saturn, you may be interested in the smaller Mars 3, their newest MSLA printer which is currently available to preorder directly from ELEGOO.

8.9″ 4K Monochrome LCD

The Elegoo Saturn 3D printer comes with an 8.9inch 4K Monochrome LCD with an HD resolution of 3840 x 2400. The monochrome LCD helps in reducing the curing times of the resin by a large extent.

This 3D printer reduces the layer printing time to 1.5s-2s, which is 60% faster than Mars Pro. What’s remarkable is that despite this, there is no compromise on the print quality, it is outstanding as ever.

54 UV LED Matrix Light Source

Matrix light source present in the Saturn consists of 54 UV LED lights with uniform light emission, ensuring superior print results and a more accurate printing size.

The set screws on the build plate assure long-lasting leveling, no need for frequent calibration, and the sandblasted surface provides a much stronger adherence, especially when printing large 3D models.

HD Print Resolution

The Elegoo Saturn 3D printer comes with an HD resolution of 3840 x 2400. It is interesting to note that it is four times more than the number of pixels that 2K screens offer.

However, owing to its large build size, the overall X/Y pixel size comes down to 50 microns. It is just a little more than the pixel size found in Mars and Mars Pro (i.e. 47 microns). Nonetheless, the print details remain exquisite.

Double Linear Z-Axis Rails

The significant size of the Saturn means it is important to ensure it has great stability throughout the printing process.

This is where dual linear rails come into play.

The 3D printer utilizes two linear rails on its Z-axis, with the lead screw sandwiched in between them. This enhances the printer’s moving accuracy and helps in keeping it sturdy and fixed.

Large Build Volume

The Elegoo Saturn has a large printing volume of 192 x 120 x 200mm/7.55in x 4.72in x 7.87in. With a print capacity like this, coupled with accelerated print speed, you can surely have a lot of fun while printing.

It gives you the freedom to print multiple full-sized models at the same time, which can dramatically improve your productivity.

Color Touch Screen

The user interface involves a 3.5-inch color touch screen that is powered by the latest firmware. Incredibly straightforward and easy to use, you are bound to have a fuss-free printing operation experience.

The design and accessibility is top-level, giving a seamless screen at the front of the 3D printer.

Ethernet Port File Transfer

Rather than just have a USB connection, you can also make use of the ethernet port at the back of the Elegoo Saturn for quick transfer speeds. It allows for file transfers through your local area network.

Most people usually stick with the USB option, but this is a nice change for people who have the desire to use it. You also have a 4 GB built-in data disk to make use of.

Long-Lasting Leveling

This 3D printer is sturdy in many ways, especially when it comes to leveling the build plate. Once you’ve tightened the set screws on the build plate, you can be sure to have a bed which should stay leveled for a long time.

You don’t need to regularly calibrate or reset your 3D printer bed level, allowing you to get more successful 3D prints down the line without all the hassles.

Sanded Aluminum Build Plate

The build plate surface has been specially sanded to promote better adhesion for your 3D prints. Through testing and experimenting, it is found that sanding the aluminum build plate gives the surface more opportunities to grip the print.

This is now a fairly standard procedure when it comes to resin 3D printers, so you can definitely benefit from this feature.

The larger counterpart to the Elegoo Mars series of printers, the Elegoo Saturn is a large-volume resin MSLA 3D printer that has found a way to offer increased build volume without sacrificing part quality. By increasing both the size and the resolution of the masking Mono LCD, the Elegoo Saturn is able to offer the same XY resolution of the Mars 2 Pro while increasing the total build volume. 

One of the best 3D printers, the Saturn impressed me with how easy it was to set up and use but the scarce availability of the typically $500 printer may be a source of frustration when searching for one to buy.

Included in the Box of Elegoo Saturn

The Elegoo Saturn ships in a well-packed box and includes all of the accessories you need to start printing as soon as the printer is out of the box. Included in the accessories box is a metal scraper (for removing parts from the build platform), a plastic scraper (for removing parts from the FEP sheet and stirring the resin), some paper funnels with a wire mesh (for filtering resin), wire cutters (for removing support material), latex gloves, and a healthy number of spare bolts, Allen keys, and other easy-to-lose parts. The included USB stick comes pre-loaded with a test print, the Chitubox slicer app, a digital copy of the user manual, and a few files from the 3D model repository site MyMiniFactory.

Design of Elegoo Saturn

Elegoo shipped this Saturn with a ‘tomshardware.com’ sticker applied to the UV-resistant lid, which was a nice touch for a review unit. As far as I can tell, this is the only difference between this unit and a typical retail unit, so my experience with this printer should be similar to yours if you purchase it directly from Elegoo.

The Saturn is a typical resin MSLA 3D printer which utilizes a vat of resin, a masking LCD, a UV light source, and a single axis of movement. It took me under five minutes to assemble this printer, and most of that time was removing foam and packaging from the box. The printer doesn’t require any mechanical or electrical assembly, and only needs to be calibrated before printing. The calibration process is almost effortless (more on that later), and the out-of-the-box experience felt quick and easy.

The Saturn uses an 8.9-inch masking LCD with a resolution of 3840 x 2400, which gives it an effective XY resolution of .05mm. The masking LCD ships with a pair of protective stickers on it during shipping, and I had no problem removing them before printing. The black protective tape around the masking LCD needs to be left on the machine, and the manual makes sure to mention this first so a new user doesn’t accidentally remove it while removing the rest of the stickers.

The resin vat on the Saturn uses four bolts that protrude from the bottom as locating posts which makes locking the vat into place a fast and repeatable process. One of the biggest problems I have when cleaning resin vats is that they typically sit with the delicate FEP film flush against the surface they are laid down on, so even a small bump in a table can possibly dent or deform them. The four posts on the corners of the Saturn’s vat keep the FEP film slightly elevated during cleaning, which is a small feature but a welcome change in design.

The resin vat also has a max fill line printed right on it which takes away the stress from potentially over-filling and spilling resin. This feature, along with the spout that is molded into the vat, indicates that Elegoo has put some thought into the needs of users who are frequently changing vats or draining and replacing resin.

Image 2 of 2

Unlike most resin MSLA 3D printers which use a single linear rail for the Z axis, the Saturn uses a threaded leadscrew and a pair of linear rails for added stability. The Saturn features a larger build volume than most MSLA 3D printers, which means more weight is suspended from the cantilevered build platform. Between these two rails and the solid machined bracket for the build platform, the Saturn is able to print without bending the build platform bracket during lift moves, and I was impressed with the rigidity of the system. 

The Saturn uses a USB stick for transferring files to the printer, as well as an Ethernet connection for adding the machine to a network. If you’re interested in using the Saturn as part of a high volume print farm, the ability to network the machine means you can transfer files without the need for an external drive. The two fans on the back of the unit provide airflow for the controller board and UV LED light source, but don’t provide air filtration like the fan in the Elegoo Mars 2 Pro. Despite the lack of air filtration, the Saturn didn’t seem to emit an odor any worse than the Mars 2 Pro during printing, but if you’re concerned about air quality you’ll want to take this into account.

Leveling the Build Platform on Elegoo Saturn

When printing on an MSLA resin 3D printer, you want the build platform to be perfectly level with the FEP film so the resin cures evenly across each layer. This leveling process can be a challenge for beginners and it can be frustrating to have failed prints due to poor bed leveling. Elegoo has addressed this problem by using a unique leveling process that is fast, simple, and easy to complete. The Elegoo Saturn uses a build platform held rigid by two bolts and includes simple step-by-step instructions for the leveling process.

Image 1 of 2
Image 2 of 2

After loosening the two bolts on the build platform and placing the included piece of leveling paper over the masking LCD, I dropped the Z axis to the home position and watched as the build platform self-leveled and sat perfectly flush. Once the axis had come to a rest, I simply tightened the two screws in the order indicated and lifted the build platform up. Compared to the leveling process on a printer like the Longer Orange 10 that uses four screws that need to be tightened in a star pattern and tend to shift during tightening, the Saturn feels almost effortless to set up.

Printing Safety with Elegoo Saturn

The Elegoo Saturn uses 405nm UV resin, a material that you need to handle safely when in an uncured state to avoid injury. The resin can be harmful when making contact with skin, so make sure to wear gloves when pouring, cleaning up, or handling uncured resin. I also make sure I’m wearing gloves when removing the build platform after a print, as the resin tends to pool on top of the platform and can drip off while the platform is being removed.

Make sure you use the Saturn in a well-ventilated room to minimize the danger from inhaling fumes. Any spills or uncured resin stuck to a surface should be cleaned using 99% Isopropyl Alcohol and the container for the resin should be kept closed and secured when not actively pouring material.

The build platform on the Saturn is designed with a trapezoidal shape that allows uncured resin to drip off and prevents it from pooling on the top of platform during printing. Despite this shape, I noticed that resin had a tendency to collect at the very edge of the platform, and I couldn’t help but wonder if a more aggressive angle or a chamfered edge would help to allow more resin to drip back into the vat during printing. This is a relatively minor point, as the majority of resin will drip downwards during printing and cleaning the edge of the build platform doesn’t require much effort.

Printing the Included Test Prints on the Elegoo Saturn

Most 3D printers include a prepared test print as an opportunity for the manufacturer to demonstrate the strengths of their machine. Despite this relatively simple premise, I’ve found that test prints can be a source of frustration for first time users as they have a tendency to have issues that most first-time users won’t be expecting.

Image 1 of 2
Image 2 of 2

Unfortunately, the Elegoo Saturn falls short in this category and my experience with the included test print was really the only major disappointment I had while writing this review. The Saturn includes a test print on the included USB drive called “_Rook_SATURN.ctb” that consists of two chess pieces with fine details on the interior and exterior of the model. This test print completes in a very reasonable 3 hours and 49 minutes, and I was impressed with the fine detail on the models once the print had completed. Unfortunately, this is where things took a bit of a turn.

The build platform on the Saturn has a sandblasted textured finish which helps cured resin adhere during printing and prevents parts from delaminating. When removing a part, a thin raft can be bent (as seen in the picture above), which allows the part to easily detach from the build platform without too much trouble. This is a delicate balance; too thin and the part won’t adhere to the plate, too thick and the part can’t be easily removed. I had no trouble with any of the parts I sliced in Chitubox, but as you’ll see below, the included test print was significantly more difficult to remove.

Once printed, the detail on the rooks was impressive, but the solid base of the model printed directly on to the build plate didn’t present an intuitive method of removal. After using the included metal scraper and attempting to gently pry the parts off, I wondered if this was a common problem or if the Elegoo Water Washable Ceramic Grey resin I was using simply wasn’t compatible with the settings provided. A quick Google search for “Elegoo Saturn Test Part Stuck To Plate” shows that this is not an uncommon problem, with some users resorting to using a rubber mallet to remove the parts from the build plate.

I was eventually able to remove the prints from the bed, but it required significantly more effort than I was comfortable with and resulted in both parts being chipped along the bottom layer. This could have been avoided with a demo model that was suspended from a support structure or simply used a sacrificial raft during printing to prevent such a wide and thick model being printed directly on the build plate. It’s worth noting this was the only time I experienced this issue during this review. The rest of the parts I prepared using Chitubox for printing were easily removed and didn’t require excessive force to remove from the plate.

Preparing Files for Printing with Chitubox

The Elegoo Saturn uses Chitubox for slicing, preparing, and exporting files for 3D printing. Chitubox is a feature-rich program which reduces the need for secondary programs to generate supports, hollow models, or make other changes that would typically require a longer workflow. The general process for preparing a 3D model for resin 3D printing goes like this:

  1. Import 3D model
  2. Angle model for printing (avoiding wide per-layer cross-sections)
  3. Hollow model
  4. 4Add drain holes
  5. Generate support material 
  6. Slicer
  7. Delete islands 
  8. Export printable file

Chitubox makes this easy, as each step can be accomplished within the software without the need to export the file to various third-party softwares. Chitubox also includes a built-in profile for the Elegoo Saturn which gives good quality results without any tweaking or modifications. I’ve been a fan of Chitubox since I started using it, and the ease-of-use and native support for the Saturn makes it a logical choice.

The profile for the Saturn that is included with Chitubox is what I would consider a good starting point for base settings. The Z resolution of .05mm is high enough to give a good quality print, but not so high as to cause an excessively long print time. The per-layer cure time of 2.5 seconds makes the Saturn a speedy printer when compared to machines with 9 second per-layer cure times like the Creality LD-002R.

For a first test, I used the Ancient Statue model from Loot Studios and prepared it using the default settings in Chitubox without making any modifications. For resin, I used the Elegoo Water Washable Ceramic Grey, which has worked very well for me in the past on the Elegoo Mars 2 Pro. This model used about 28 grams of resin and printed out in just under 4 hours, which seems in line with what I would expect from a Mono LCD 3D printer.

Image 2 of 2

The Water Washable Ceramic Grey resin looked great after printing, and the support structure removal process is simplified by not requiring any isopropyl alcohol or other chemicals to remove the excess resin. A quick soak in a small tub of hot water dissolved the excess resin from the surface of the printer and also softened the support structure. After removing the support structure, I cured the model for a total of two minutes in 30 second increments to prevent it from warping.

It’s worth taking a moment to reflect on the printing process so far before we really look at this model. The steps to create this model are all simple and straight-forward, and a beginner could easily follow along to calibrate the bed, fill the resin vat, and process the file for printing. The resulting print looks sharp and detailed, and even small details like the cracks in the stone of the statue resolve and don’t require any touch-up work. Putting aside the large format nature of the Elegoo Saturn, it’s easy to understand why this machine is in such demand; it’s easy to use, gives good quality results, and the native software doesn’t require tinkering or tweaking.

Print Size Comparison of the Elegoo Mars 2 Pro vs. Elegoo Saturn

Image 1 of 2
Image 2 of 2

The Elegoo Saturn shares many design similarities with the Elegoo Mars 2 Pro, so it makes sense to compare the two 3D printers directly. The Saturn uses a higher resolution masking LCD, but the increased size of the LCD means the XY resolution (pixel size) is .05mm on both machines. This means a part printed on the Mars 2 Pro and Saturn, using the same settings, will result in two parts that should be indistinguishable from one another.

With a retail price of $500, the Saturn offers nearly 3 times the total build volume (280 cubic inches vs. 100 cubic inches) of the Mars 2 Pro, which retails for $330. If you’re interested in throughput and high-volume printing ability, the Saturn is able to produce a large batch of parts at the same resolution as Mars 2 Pro. However, if you’re looking for a higher resolution finished part and aren’t interested in a large build size, a 4K LCD printer like the Phrozen Sonic Mini 4K would be a better choice.

Printing a Large Assembly on the Elegoo Saturn

The large build volume and fast per-layer print time of the Elegoo Saturn make it ideal for printing models that would ordinarily be too large or time-consuming to print on a smaller MSLA resin printer like the Longer Orange 10. To test out the ability of the Saturn to print large models in multiple pieces simultaneously, I loaded up the Olympus Rider model from Loot Studios. This model of a winged Pegasus complete with rider armed with a spear prints in six individual pieces and a single large base.

Unfortunately, the auto-placement feature in Chitubox wasn’t able to automatically place all of these parts on the build platform in order to print them in a single piece. After manually rotating the parts myself, I was able to get everything except the base of the model onto a single tray. This would be an ambitious print under the best of circumstances, as it covered a large portion of the surface area of the build platform and would create a large amount of suction when moving the platform up and down. After slicing, Chitubox generated an estimated build time of 7 hours and 10 minutes as well as a material usage of 128 ml. I wasn’t sure if the Saturn could handle a print this ambitious, but I was eager to see if this hard-to-find machine could live up to its reputation.

The Saturn printed every single part on the build platform without any defects, and I was genuinely surprised and impressed with how easily the Saturn could handle a large and complex build like this. The Elegoo Water Washable resin created a support structure that was easily removed and left minimal pockmarks on the finished model.

After a rinse and cure in the Elegoo Mercury Plus Cure/Wash station, I laid out the parts and assembled the model using DAP RapidFuse CA glue, a favorite of mine for making strong bonds on resin prints like this one. The final result is a finely-detailed print that measures nine inches wide and six and a half inches tall, and it is one of the largest resin MSLA prints I’ve ever made. The 3D model to 3D print process was seamless and easy, and this model earned the Saturn a permanent place on my personal list of all-time favorite 3D printers.

Printing Multiple Miniatures Simultaneously on the Elegoo Saturn

One of the key abilities of a large build volume resin MSLA 3D printer like the Elegoo Saturn is the ability to print multiple parts simultaneously. The Saturn is a popular printer for users interested in tabletop gaming, and the large build volume is ideal for printing out multiple miniatures in a single print. Because the print speed is dictated by the number of layers and not the number of miniatures, printing a single miniature or a full build platform full of them takes the same amount of time.

As a test of the printer’s performance, I filled the build platform with some of the enemies from the Loot Studios Ghostly Odyssey release which features a mix of detailed creatures and human 32mm miniatures.

Image 1 of 2
Image 2 of 2

After importing the models into Chitubox, I manually laid them out to prevent the support structure rafts from touching to reduce the overall total surface area of the bottom cross-section. Chitubox handled the slicing of this large tray without breaking a sweat, and I was easily able to fit a mix of models and bases for a total of 12 parts printing simultaneously. Chitubox gave an estimate of 3 hours and 51 minutes, which is an attractive print speed for such a large yield of parts.

The models have a support structure already generated, so after slicing all I had to do was detect and remove the islands (small, unconnected pixels that can cause floating bits of resin) and scroll through the layer view to check for any missing geometry. This is a quick and largely-automated process made possible by the Chitubox app, which I am grateful that Elegoo has internally decided to endorse as opposed to attempting to make their own slicer app which may lack some of this functionality.

As I expected, the print was completed without incident. Because of the large number of support structures, the first hour or so of the print is just hundreds of tiny cylinders (as seen in the Chitubox preview above). Every time the build platform lifted, it sounded like a Velcro strap being removed as each of the tiny support structures delaminated from the FEP sheet with a tiny pop sound. I couldn’t decide whether the sound was reassuring or not, but in the end, I’m grateful for each pop because it meant the printer was working correctly.

The support structures were easy to remove after a quick soak in hot water, and the models all felt like they had been cured enough to be solid. In particular, the swords and wings on the smaller models were easy to free from the support structure, and I wasn’t concerned with them breaking off or shattering during the cleaning.

Image 2 of 2

Even on these 32mm miniatures, the details were crisp and features like the individual feathers on the harpy model resolved well and could be easily distinguished. If you’ve used a printer like the Anycubic Photon Mono or the Elegoo Mars Pro, this level of resolution (.05mm) is directly comparable with what you’re used to, so the big benefit of the Saturn is being able to increase your output without sacrificing quality.  

Bottom Line

The Elegoo Saturn is about as hard to find as a PlayStation 5 right now, and it tends to sell out immediately after each restock at Amazon and the Elegoo official store. After using it for this review, it’s clear to me why the printer is in such high demand: it’s fast, relatively inexpensive, and offers a build volume ideal for printing multiple parts simultaneously. The Saturn regularly sells for over $700 on second-hand sites like eBay, so finding one may prove to be a challenge for the foreseeable future.

I asked Elegoo to comment on the relative scarcity of the Saturn, and they indicated a combination of high demand and rigorous quality control were to blame for the shortages. 

These two printers are too hot sale, so they always sold out. In fact, we have arranged more products for Amazon every week, but it sold out when available. In addition, our company will test the machine before selling, so it costs some time.

The high-yield nature of the Saturn makes it ideal for printing multiple miniatures simultaneously, so there’s no doubt this printer will be a hit among hobbyists who are interested in printing custom miniatures. The large build volume also offers the ability to print large parts in a single print, something that smaller machines like the Creality LD-002R aren’t able to accomplish.

The overall trouble-free printing experience of the Saturn makes it appealing to beginners as well as more advanced users, but the $500 retail price (if you can even find it for that) might be a little high for a first printer. If you’re interested in a lower cost alternative, the Elegoo Mars Pro or the Anycubic Photon Mono both offer a similar printing experience at a lower price point.

Elegoo Saturn in-depth review, what I perceive to be a very serious issue, and the fix for it!

It’s incredible how 3D printers have come a long way from as recently as five years ago. Back then, when you say 3D printer, people would think of a costly machine that would take too long to print something. And they wouldn’t be right.

But things have changed. You now have 3D printers that are speedy and can be within budget. But even when they’re affordable, there are no apparent tradeoffs. You still get a quality machine that can deliver eye-catching prints in high resolution.

The Elegoo Saturn is one of these devices. Using masked stereolithography technology, the Elegoo Saturn can deliver speedy print times with decent resolutions. It’s also a printer that offers a big build volume (build plate) at a price that you would love.

What are the features of the Elegoo Saturn that you should know? And should you buy it? Read on and discover more about this 3D printer.

Monochrome LCD

If you only need to read one section, then this should be it. Elegoo Saturn is a masked stereolithography 3D printer.

Stereolithography traces its meaning to two Greek words:

  • Stereo, which means solid
  • Lithography, which means writing

Your stereolithography printers are creating objects using light. Probably the best-known types of stereolithography use laser and digital light processing.

  • Laser-based stereolithography uses an ultraviolet laser to create your prints. These lasers are reflected onto the print area, and the light solidifies the resin on a layer per layer basis.
  • DLP stereolithography, on the other hand, projects light onto the resin.
  • Masked stereolithography replaces the laser and projector with an LCD screen.

Benefits of Masked Stereolithography

Masked stereolithography prints your objects faster than a laser SLA printer, especially when you’re printing denser and larger items. What’s more, because these LCD panels are the same ones used for smartphones, availability is not an issue.

They are mass-produced, so LCD panels in these 3D printers cost less too.

Elegoo Saturn Is Faster than Most Other MSLA Printers

If MSLA printers, in general, are faster than laser stereolithography printers. That is because of the technology that allows the printer to print an entire layer of your object as opposed to the piece by piece printing done by lasers.

But because the typical MSLA uses the same LCDs as your smartphones, these colored LCDs have filters to deliver red, green, and blue to your screen. These filters are blocking some of the light that would typically go straight to the resin and cure it.

So when it comes to MSLA printers, monochrome LCDs are not a bad thing. It just means a printer can print your objects a lot faster than most MSLA printers.

And true enough, the Elegoo Saturn has a printing speed of 1.2 inches (30 millimeters) per hour. The monochrome LCD significantly reduces the curing times of the resin because it has a more intense light.

High-Resolution LCD

Not only is the Elegoo Saturn fast, but prints are impressive as well. The 4K screen measures 8.9 inches (226.06 millimeters) with a 3,840 by 2,400 pixels resolution. That is four times the number of pixels compared to 2K screens.

However, because of the huge build size of Elegoo Saturn, its overall X/Y pixel size rests at 50 microns, which is slightly less detailed than the X/Y pixel size of both Mars Pro and Mars.


The Elegoo Saturn’s design draws comparison to the company’s own Mars and Mars Pro printer: Saturn looks the same as Mars and Mars Pro, only bigger.

Saturn’s base measures 11 by 9.4 inches (280 by 240 millimeters) with an all-metal build. It puts the control panel at the front. This touch display measures 3.5 inches (88.9 millimeters), and it is how you interact with the printer.

The USB slot of this printer is located on the right side, fortunately making it more accessible than the USB slot on the Mars that Elegoo put at the back of the machine.

The vat where you put the resin is also larger than the one on Mars and Mars Pro, measuring 7.6 by 4.7 inches (192 by 120 millimeters). Putting in or changing the resin is now easier and less messy because of the pouring aid.


You will surely be impressed with the Elegoo Saturn’s Z-axis. The lead screw is sandwiched between two linear rails, making it very stable and sturdy.

Notable Features

So what are the features that you should know about the Elegoo Saturn?

  • The 4K monochrome LCD delivers a more intense light source for faster curing times. This LCD panel is much bigger and more durable than the ones you find on Mars and Mars Pro.
  • Dual linear rails provide more stability to the printer.
  • A print resolution of 50 microns means that this printer can deliver bigger prints with the same level of detail as the Elegoo Mars.
  • Two cooling fans help to keep the temperatures low while also helping to make the LCD last longer.
  • The touch display is big enough at 3.5 inches (88.9 millimeters), allowing you to operate the device efficiently.
  • Ethernet connectivity is a technology that allows you to print from your computer and even remotely.
  • The prints will adhere better to the bed because of the sandblasted surface. That means that you’d have less printing errors.


Elegoo Saturn works with a wide variety of resins. What’s more, the company manufactures and sells its own resins, but you can use third-party products with this printer.


With all the nifty features, a sizable print volume, fast printing times, and other attractive benefits, you’d expect to pay a lot for the chance to own an Elegoo Saturn.

However, this printer retails anywhere from $300 to $600, depending on where you look. It is sold on Amazon, as well as other online retailers. But it is always out of stock.

Huge Build Volume

We’ve saved the best for last. What can make an affordable and fast 3D printer even better? A significant build volume, of course.

In this regard, the Elegoo Saturn doesn’t disappoint. It has a build volume of 7.6 by 4.7 by 7.9 inches (192 by 120 by 200 millimeters). These dimensions significantly beat out the Elegoo Mars: Saturn has 3.5 times the print volume of the Elegoo Mars.

Bottom Line

We certainly wish that all companies, no matter what their product is, would be like Elegoo. They have taken an excellent product in the Elegoo Mars and made it better, faster, and bigger.

The company has not disappointed its users with the release of both Elegoo Mars and Mars Pro, and they didn’t start disappointing with the Saturn. With a massive build volume and faster printing times, while keeping the price down and the print resolutions the same, Elegoo has made Saturn the go-to 3D printer for people who like the have professional quality prints without spending too much.


  • Works really fast and efficiently
  • Breezy and headache-free operations right out of the box
  • Compatible with 405 nm UV-sensitive resins


Comparison to other Elegoo 3D the printers

We’ve compared the Saturn with Elegoo’s earlier printers: Mars and Mars Pro. It is easy to see just how the company has improved its offerings over time. The Saturn is bigger and faster than both of its older siblings and yet delivers the same print resolutions as the smaller printers.

Here’s a side-by-side comparison of these three printers to make it easier for you to see how the Saturn compares to earlier devices from the same company.

Alternatives to the Elegoo Saturn 3D Printer?

If you’re not impressed with the Elegoo Saturn, there are other Elegoo printers such as the Mars and Mars Pro that you can look at.

But if you’re looking for a printer from other manufacturers, here are similar 3D printers that we can recommend:

Peopoly Phenom

The Peopoly Phenom stands out because of the build volume that it offers, something that you cannot find in other resin-based 3D printers. You can easily create tall 3D models that can reach up to 1.6 inches (40 centimeters) high. This printer is one of our recommended alternatives for the Phrozen Transform.

The Peopoly Phenom is an MSLA printer, much like the Elegoo Mars and Saturn. As such, it is also faster than a laser SLA printer because it prints one whole layer at a time.

This printer has a bigger LCD screen, measuring 12.5 inches (317.5 millimeters) with a 4K resolution. It also features an array of fans and a heat sink, which helps keep the 3D printer cool while it is hard at work.

And if you’re opting to buy the Peopoly Phenom, you will want to clear out a lot of space on your desk. This 3D printer is huge, measuring 17.8 by 14.3 by 30.7 inches (452 by 364 by 780 millimeters). It weighs 92.5 pounds (42 kilograms).

The color touchscreen, which is the 3D printer’s user interface, measures 4.3 inches (109.2 millimeters). It is big enough to operate the printer efficiently, and it comes with all the information you need. You can know the printing time, a live visualization of the layers being printed, and the total number of layers.

Phrozen Sonic Mini

The Phrozen Sonic Mini features a monochrome LCD like the Elegoo Saturn, which means that it prints faster than other SLA printers out there. The Sonic Mini is one of our choices for the best 3D SLA printer for 2020.

The thing with the Sonic Mini is that it is very affordable. This printer was introduced and sold for less than $200. But because of its performance and printing speed, prices increased over time.

Some of the features you should know include:

  • Monochrome LCD: Gives you fast printing times because the resin is exposed to more intense light, and you get an entire layer being printed.
  • XY resolution of 62 microns
  • Uses ChiTu board and ChiTuBox software, which is a breeze to use when you’re preparing your model
  • Affordable price, at around $200 to $300

Before You Buy

With the super-fast printing speed at a very low price, the Phrozen Sonic Mini does have a few tradeoffs. For one, the printer’s outer shell is made of molded plastic, not metal.

The resin vat is also plastic. What is more, this printer may use the same monochrome LCD as the Elegoo Saturn, but it has a much smaller build volume at only 4.7 by 2.7 by 5.1 inches (120 by 68 by 130 millimeters).


  • Dimensions: 9.8 by 9.8 by 13 inches (250 by 250 by 330 millimeters)

  • XY resolution: 62 microns
  • Touchscreen display: IPS measuring 2.8 inches (71.12 millimeters)
  • Connectivity: USB


  • Very affordable
  • Straightforward operation
  • Faster than most 3D printers


  • The USB port is difficult to reach
  • Small print volume

Photon Mono SE

The Photon Mono SE comes from Anycubic, another reputable manufacturer of 3D printers. The Photon Mono SE uses a monochrome LCD to cure the resins for your 3D objects. And like the Elegoo Saturn, you can expect fast printing times with this 3D printer.

The monochrome LCD screen measures six inches with resolutions of 2,560 by 1,620 pixels with an XY-resolution of 51 microns. It is not the most precise 3D printer available today, but the print quality is still good.

The Photon Mono SE has a build volume of 5.1 by 3.1 by 6.3 inches (130 by 78 by 160 millimeters). That is more than the Phrozen Sonic Mini, and the Elegoo Mars Pro can give you.

This 3D printer has an upward opening door, which might present a problem when you’re refilling the resin. It uses two linear rails for its Z-axis, while its shell is made with metal. These materials make the printer more stable. Check out our full Photon Mono Review.

Features You Should Know

The Anycubic Photon Mono SE has several features that can help you decide whether to buy it or not.

  • You can use the Anycubic App to see how far along your printing job is going, as well as tweak the print settings even without going close to the printer.
  • The printing platform is made with brushed aluminum
  • Responsive and intuitive user interface

  • XY resolutions: 0.05 millimeters
  • Pixel resolution: 2,560 by 1,620 pixels
  • Printing speed: 3.1 inches (80 millimeters) per hour


Question: What is the big deal with bigger build volumes anyway?

Answer: A lot of 3D printing enthusiasts will tell you to get a printer with a significant build volume. There are many benefits of owning one.

• Print Bigger Pieces:
You get to print the 3D model in its entirety. A big build volume allows you to print your models in one piece, rather than printing it in parts and then assembling them afterward.

Not only does printing and assembling more parts take time, but it also costs more. What’s more, if you have to work with a smaller printer, you will lose details in the 3D model because you are forced to scale everything down.

• Batch Printing
When you have a bigger build volume, you can have more pieces when you print in batches. For instance, you can easily print ten small 3D models with a printer that has a massive build volume as opposed to only three to five in smaller printers.

In effect, you save a lot of time and resources with a bigger build volume because you no longer have to do a lot of batches.

Question: What are the benefits of MSLA printers?

Answer: We have touched on how MSLA printers cost less and print faster than other types of stereolithography printers.

But there are more benefits to owning an MSLA printer like the Elgoo Saturn:

• It can produce more accurate parts, as well as include more details than other types of 3D printers.
• It has a smooth finish, so you can create stunning prototypes without spending a plot of time post-processing.
• There are many specialty resins available not just for MSLA printers but also for other types of SLA printers. You can get castable and flexible resins if you need them.
• There are some interesting things that you should know about SLA printers, as well.

These are what you might call the downsides of owning one:

• SLA Printer parts are less durable than those printed with other types of 3D Printers, such as those that use fused deposition modeling technology. As such, if you ar printing functional parts, it is best to avoid doing so with an SLA printer.
• SLA prints are vulnerable to sunlight. As such, these parts will change, deteriorate, and degrade over time.
• When printing with an SLA printer, you typically need strong supports. This process might add to post-processing time and work.

Should You Buy the Elegoo Saturn?

When it comes to affordable 3D printers, the Elegoo Saturn ticks a lot of boxes. Aside from the attractive price, you also get a printer that has a massive build volume, allowing you to get prints that measure 282 cubic inches (4,624 cubic centimeters).

It uses one of the newest technologies, MSLA, with a monochrome LCD that allows it to cure resins in two seconds and print up to slightly more than an inch (30 millimeters) per hour.

So while the Elegoo Saturn can be hefty and heavy, it’s really a difficult printer to pass up. However, it’s not always available and can be out of stock at several retailers, including the company’s own online store. Fortunately, there are alternatives that you can find.

If you want something with a bigger build volume, you can go for the Peopoly Phenom. This printer can give you a build volume of 1,043.9 cubic inches (17,106.3 cubic centimeters) and almost twice the maximum height. But you might be turned off by the price, which is more than six times that of Elegoo Saturn at $2,000.

If you’re working within a smaller budget, both the Phrozen Sonic Mini and the Photon Mono SE are closer to the Elegoo Saturn when it comes to pricing. Both of these printers use monochrome LCD and can deliver fast printing times. But both have smaller build volumes than what’s offered by Elegoo Saturn.

The Final Word on the Elegoo Saturn

The Elegoo Saturn is one of those 3D printers that gives you what you want: fast printing times, huge build volumes, and 4K clear printing resolutions. It also helps that the manufacturer doesn’t scrimp on the materials, giving you a sturdy, durable, and stable printer. Plus, it will not cost the buyer an arm and a leg to own this device.

It’s hard to go wrong with such a 3D printer, and we don’t have problems recommending it at all, if only Elegoo manufactured more of them, as it’s almost always out of stock.

The Elegoo Saturn 4K packs a number of unique features such as a large build area, fast printing speeds, and 4K monochrome LCD screen, making is a compelling choice for 3D printing.

8.9-inch 4K Monochrome LCD Screen

Rocking an 8.9-inch 4K monochrome 3840 x 2400 LCD screen, the Elegoo Saturn can produce high-quality 3D-printed objects. When compared to a traditional RGB LCD screen, monochrome LCD screens yield several advantages. Namely, monochrome LCD screens benefit from faster printing speeds than standard RGB LCD screens since there's a decrease in exposure time since ultraviolet (UV) transmission can be as high as 6% on a mono LCD screen versus around 1% on an RGB LCD screen. What's more, monochrome LCD screens can last longer than RGB LCD panels with over 10,000 hours. 

Fast Printing Speeds - 1.5-2s Layer Printing Time

Because of its monochrome LCD screen, the Elegoo Saturn reduces the required exposure time significantly. With its 1.5-2 second layer printing time, the Saturn MSLA 3D printer boasts print speeds about 60% faster than the Mars Pro resin 3D printer. 

UV Matrix Light Source

A UV matrix comprised of 54 ultraviolet LEDs ensures extreme light uniformity. The resulting 3D prints are high-quality with precise fine details and a smooth finish. 

Ethernet Port and 4GB onboard Storage

Sporting an Ethernet port and 4GB of built-in storage space, the Elegoo Saturn offers network connectivity. You can drop files over the network directly onto the Saturn for 3D printing. Alternatively, a side-located USB port lets you plug in a flash drive with 3D printable files. 

Big Print Area - 192 x 120 x 200mm (7.55 x 4.72 x 7.87 inch)

In addition to the rook test print, I tried out some fun prints. Eastman's Deadpool bust has become a sort of unofficial resin 3D printer benchmark. Deadpool rose majestically out of its resin bath with resplendent details. Everything was high-quality, from the lines and creases on Deadpool's suit to the ridges of his sword handles, and the easily legible letters spelling out "Eastman" on the back of the stand.

Software - Chitubox

Like most other resin 3D printers, the Elegoo Saturn 4K MSLA printer uses Chitubox for slicing 3D printable files. While there is a slight learning cure to adding supports or hollowing out prints, it's easy enough to learn, and that's a universal challenge of SLA 3D print slicing. Though there is a version of Chitubox pre-loaded on the bundled flash drive, you can download Chitubox from the official website and add the Elegoo Saturn 4K profile. I had no issues printing straight away with stock Elegoo Saturn profile settings.

The Competition - Elegoo Saturn Alternatives

While most resin-based SLA 3D printers feature smaller build volumes than traditional filament FDM printers, there are several large resin 3D printers on the market. The Anycubic Photon Mono X offers a 192 x 120 x 245 mm (7.55 x 4.7 x 9.6 in.) build volume and an 8.9-inch 4K 3840 x 2400 monochrome LCD screen. Like most Anycubic printers, the Photon Mono X delivers fantastic build quality. And with nearly-identical specs to that of the Elegoo Saturn, the Photon Mono X features the same combination of fast printing speed and high-quality prints as the Saturn. But it's almost twice the price of the Saturn. As such, the Elegoo Saturn is a better value.

The Phrozen Sonic Mighty 4K sports a large 9.3-inch 3840 x 2160 LCD monochrome screen and a 20 x 12.5 x 22 cm build area. Unfortunately, there's no network connectivity and its build quality is middling. 

The Epax E10 provides a choice between an 8.9-inch 4K mono LCD screen and a 10.1-inch 5K mono LCD screen. It affords a modular design for upgradability. It's customizable and includes a 192 x 120 x 250mm build volume on the 4K variant with a  216mm x 135mm x 250mm build volume on the 5K iteration. But it's pricey in both forms and not the easiest to upgrade. 

With its 8.46 x 5.11 x 7.87-inch build volume and a 10.1-inch LCD screen, the QIDI S-box is a good, big resin 3D printer. Disappointingly, its 10.1-in. LCD screen is only 2K, not 4K. While print quality is still great, it won't quite match the high-precision of a 4K monochrome LCD screen. 

Final Thoughts - Should You Buy the Elegoo Saturn?

The Elegoo Saturn 4K MSLA resin 3D printer delivers unrivaled performance, size, and user-friendliness on a budget. It's well-priced at around $500 USD. Boasting a large build volume, the Elegoo Saturn isn't constrained by the limitations of most standard-sized resin-based 3D printers. A 4K monochrome LCD screen delivers top-notch print quality with extreme precision that translates to excellent fine details. Additionally, 1.5-2s per layer curing times enable fast print speeds for a good mix of quality and quantity. Because of its massive build volume, the Elegoo Saturn is just as comfortable churning out large, wide objects as it is printing multiple minis in one batch.

Amenities such as an Ethernet port and 4GB of onboard storage for over-the-network file transfers make the Saturn a great option for most makers. A built-in air filtration system would have been nice, though I noticed little to no smell with the acrylic hood on. If you don't need the big print volume, the Elegoo Mars 2 Pro or another smaller resin 3D printer will do just fine. But for printing large objects or batches of minis, the Elegoo Saturn 4K resin 3D printer is hands-down the best option on the planet. Ultimately, the Elegoo Saturn MSLA is the best big 3D printer on the market.

2021 Hands Down Best Printer For The Money - Elegoo Saturn 4k Mono Resin 3D Printer


Two-minute review

The Elegoo Saturn is a mid-sized MSLA printer that closely resembles a scaled-up version of one of the Elegoo Mars series of printers from the same company. If you've even slightly dipped your toes into the world of 3D printing, chances are you'll have heard about Elegoo from numerous YouTube reviews and online resin printing tutorials, with the Elegoo Mars making a frequent appearance thanks to its affordability and reputation for reliable, high-quality prints.

This obviously means that the fresh-faced Elegoo Saturn has some pretty big shoes to fill. Thankfully, it can print some big shoes of its own. Its larger size stands out as a benefit to consumers looking for something with a larger-sized print bed to accommodate bigger prints, reducing printing time for models that would have previously needed to be cut into sections using software and then printed in batches for later reassembly.

A quick explanation for anyone who isn't familiar with 3D printers, consumer models generally fall into just two categories:  stereolithographic (SLA) and fused deposition modeling (FDM). 

FDM-type printers use a melted filament to build up a model layer by layer onto a heated bed, with a motor-controlled nozzle moving around to create your design. SLA printers use a print bed submerged into a vat of UV reactive resin, and then a LED light system will flash, curing each layer within the tank. The Elegoo Saturn falls into the latter category, which means there are a vast array of pros and cons when stacked up against FDM printers like the Anycubic Vyper.

While FDM printers can typically print at much larger sizes owing to their available print bed volume, they struggle to pick up fine details and many prints, even the well-optimized ones, will have lines running throughout where the layers were built up. Resin-based printers on the other hand succeed in delivering great detail in their prints, but the size is typically much more constricted.

This is where Printers like the Elegoo Saturn will win some favors from consumers looking to print bigger models, with higher detail than what's achievable using FDM printers, and thankfully, it delivers on that beautifully.

The Saturn printed reliably and at a much faster speed than an FDM printer too, and the only major gripes we found were those typical of all resin-based printers, and therefore not restricted to this particular product itself. It does exactly what it sets out to do with minimal fuss, equipping you with the means to bring your ideas into a resin-submerged reality.

The Elegoo Saturn MSLA printer is available through the Elegoo website or third-party retailers like Amazon, with many region-specific links listed directly on the Saturn product page.

You can expect to pay $500 / £440 / AU$700, though we note that stock availability can vary depending on your location, with many of the Australian sites listing the Elegoo Saturn as 'out of stock'.

Net Weight: 13.5kg

There's minimal assemble required for the Elegoo Saturn, and the packaging is protected with plenty of foam and plastic sheeting to prevent any dents or scratches during shipping.

You'll also get a kit with some accessories to help both assembly and the printing process itself, with latex gloves and paper filters for cleaning resin after use, spare bolts, some paper facemasks to protect you from resin fumes, and a USB drive that you'll use to load STL files into the printer.

You also get a few tools in the kit, such as some wire cutters for removing supports, a plastic scraper for delicately removing any failed prints from the FEP sheet and a metal scraper for removing prints from the build plate. These are sufficient but you'd fare better buying some professional quality tools if you're planning to print frequently.

As mentioned, the overall design of the Elegoo Saturn is similar to its existing Elegoo Mars line of resin printers, though noticeably bigger if you compare the two side-by-side. As with many SLA and MSLA printers, the Saturn has a submergible build plate and a vat for resin. You get a semi-transparent red hood to keep out UV and other debris from falling into the resin, with a touch-reactive 3.5-inch screen located on the front of the printer to operate it.

The chassis that contains all the important mechanisms is metal, so the printer is fairly heavy (weighing in at 13.5kg), though an adult will have little issues moving it around. You might want to supervise any children around it though, not just due to its heft, but also because working with resin requires you to pay close attention to health and safety. Always make sure you're wearing gloves and either a disposable face mask or a professional respirator that's rated for fumes.

Elegoo likes to mix up the location of the USB port on its machines, but while models like the Mars 2 pro have it located on the back of the printer (requiring you to move the printer or leave access to the rear, which isn't ideal), the Saturn, thankfully, has it on the right-hand side. 

Having it on the front would have made more sense to us to allow easier access and reduce the need to move the printer around (and recalibrate it as a result), but it's certainly preferable to having it on the rear. Still, the power switch for the printer is still located on the back, so take care when trying to switch the device on or off.

You can also plug the Saturn into a network connection via an available port on the rear, which is ideal for people looking to add a larger printer to a high-volume printing setting or farm. Using an ethernet, you can control the Elegoo Saturn remotely from a laptop or PC.

The aforementioned resin tank is a blessing compared to some other models on the market that use a side-mounting system. Instead, the Saturn is top-mounted, which makes the process of removing it much easier and less prone to spillage. You also get a handy 'spout' on one side to help you decant out resin back into the bottles, so Elegoo is clearly taking steps to keep users clean of unnecessary resin-related mess.


The Saturn has an 8.9-inch masking LCD with a 4K resolution of 3840 x 2400, so you're getting an XY resolution of .05mm, or 50 microns, compared to the ever so slightly more detailed 0.047 mm (47 microns) found on the Mars and Mars Pro. Smaller is better regarding microns for resin printers as it allows for finer detail, but a difference of 3 microns is going to be indistinguishable to the eye. If you've used the Mars or Mars Pro printer and were happy with your print results, chances are you'll love the Saturn's quality too.

Take note that the LCD will have a protective film on it during shipping, and this will need to be removed prior to use, but take care to not remove the black tape that surrounds the screen itself.

The Saturn lacks an air filter and a rubber seal like those seen in the Elegoo Mars 2 Pro, so make sure you're setting it up in a well-ventilated area. Even without the air filter, the cooling fans can be a little loud, but providing you're not trying to sell in the same room while it's operating (which we would advise against), you won't hear it behind a closed door.

The build plate for the Saturn will need leveling before you start pouring resin into the vat, but the process to do this is very straightforward, more so than many other popular printers on the market. All you need is a piece of paper, something that's supplied in the box, but a standard piece of printing paper will work just as well.

Simply loosen the two bolts on the build platform using the allen key supplied and place a sheet of paper over the LCD display. The Elegoo Saturn can then be set to self-level, after which you just need to re-tighten the bolts and you're ready to start printing.

The Elegoo Saturn has a few files included on the USB drive that it ships with, including a download for the ChituBox slicing software. We found that the printer profiles were already available so you shouldn't need to manually upload them yourself, and the software allows you to make the usual adjustments to optimize your prints.

The application itself is very user friendly while also being feature-packed, eliminating the need for secondary programs. ChituBox can generate supports for files and estimate how much resin you'll need to complete a print, as well as estimated costs. There are other applications that you can use with Elegoo printers, but we certainly don't have any complaints about this software.


There are a few different resin types offered by Elegoo such as 'Eco' and 'Water Washable', but we opted for the standard in opaque black. The supplied test files that come pre-loaded onto the USB drive are something we call a 'torture test' or bench, a model designed to put a printer through its paces with a complicated design.

Right off the bat, there's a glaring issue with these files that reflects poorly on the printer if you've never tried 3D printing before. As they're unsupported and built directly onto the build plate, it's almost impossible to remove them without damaging the model as they adhere very strongly. The metal scraper supplied in the Elegoo Saturn kit is too thick to slide underneath the model so you're just going to cause damage trying to dislodge them.

If you find yourself in the same predicament there are a few things you can do. One would be to load the file into ChituBox and manually add your own supports to elevate it from the build plate. Another is to buy a razor window scraper that can wriggle under the build, or pour boiling hot water over where the print is stuck to gently expand the plastic and help it dislodge more easily.

Something we would have loved to see is a FlexPlate system, a slim magnetic cover for the build plate that allows easy removal of stuck prints due to its flexibility. You can buy these from a range of different 3D printing websites, but it would have been a great idea for Elegoo to implement something similar into the Saturn design.

Removal difficulty aside, the benchmark prints were a success, with all areas of the models printing with no detectable issues. Alongside other benchmarks, we ran a test print of a minuscule goblin figurine to see how much detail the Saturn could pick up on a smaller scale and we were pleasantly surprised by how small you can go. The loincloth is so thin that you can see light shining through, but all of the detail has been picked up and despite its sheerness, it printed without snapping.

In fact, every model we printed on the Elegoo Saturn was crisp and clean. You have to be careful with the delicate FEP film at the bottom of the resin tray (the thin, clear plastic film that contains resin while allowing curing UV light to pass through) as it can easily be pierced if you're trying to clean any resin that's started to cure on the surface, and Elegoo doesn't provide any replacement sheets in the box. Thankfully, you can buy these easily online, typically on the same website you used to purchase the printer so we would advise grabbing a pack of replacements for when an accident occurs.

In all, this is a great MSLA printer and it's no wonder that stock issues have reared their head. With its larger size, printing enthusiasts don't have to compromise quality to upscale the size of their models so the high demand is to be expected. If you find one in stock, the Elegoo Saturn is a fantastic buy for both newcomers to 3D printing and seasoned veterans looking for a mid-sized printer.

Buy it if...

You want to print bigger figurines
With a build volume of 192mm(L) x 120mm(W) x 200mm (H), you won't need to separate your models into small pieces within slicing software. Not only that, but you have more space available to print smaller models in greater quantities.

You need fine details on your prints
Compared to FDM printers and some other SLA printers on the market, the Elegoo Saturn makes light work of complex models that have a lot of small details on them.

You don't want to complicate things
From unboxing to printing our test benchmark, the entire setup was quick and very straightforward and only took around 20 minutes. In fact, there's very little about the Saturn that's complex.

Don't buy it if...

Time is of the essence
Depending on your location, you might find the Elegoo Saturn is harder to find than gold dust due to high demand, though things do seem to be improving in certain regions.

You don't have a lot of space
It's far from the biggest 3D printer on the market, but if you need something small and lightweight to fit into a cramped shelf, the Saturn might be a little too large for some desktops.
