The Mars 3 is a Mono LCD (liquid crystal display) 3D resin printer from Elegoo. It is the third major revision in their Mars series and this heritage shows. Resin LCD printers create the 3D parts by curing a single layer of resin onto the underside of a submerged build plate. Each additional layer is fused on to the previous with a UV light as the platform rises out of the tank of liquid resin.

Resin printers are ideal for highly detailed models as their layer heights are much smaller than a traditional FDM printer, to the point the layer lines are no longer visible under casual inspection. The trade of is that until cured with exposure to UV light, the not super friendly for you or the environment resin can be hazardous, though if the prints and waste byproducts are treated properly this is not a problem. Further more, more friendly and easier to work with resins are being rapidly developed and put out into the market by both Elegoo and other manufacturers.

The build volume is 89.6 x 143.36 x 175mm - a very generous build volume given the small footprint of the machine and an improvement on the Mars 2 whilst still maintaining a higher print resolution thanks to its new 4k screen.

This monochrome 4k LCD screen, in partnership with the newly designed COB light source, allows the machine to cure layers in just a couple of seconds (1.5 to 3 seconds depending on the resin and chosen layer height). A huge and noticeable improvement on some of the earlier models.

I"ve received several machines from Elegoo over time and each and everyone has always been thoughtfully packed. The Mars 3 is no exception. Strong box, dense foam, and protective sheets easily defend the machine from the bumps and jolts the global delivery network might throw at it in transit. There won"t be any tears when opening the box.

With the exception of some resin to print with and some alcohol to clean the print with after printing, everything else you will need for your first prints are included. Elegoo and other manufacturers omit the two mentioned liquids as they complicate shipping when bundled in with the electronic device. Here is what they have included with the printer for you:

Though despite the added curves and arches making it more reminiscent of Space X"s Dragon capsule, the area containing the touchscreen controls, power button, and USB port seems simpler and more prominent.

It"s a simple case of removing the resin tank using the two thumbscrews on either side then adding a sheet of paper on top of the screen. Slide the build plate onto the arm of the printer and tighten using the giant knob up top. We can then loosen the two silver bolts just above the build platform so that it can freely move. The Allen key you"ll need is included.

Start the homing sequence using the onscreen controls and watch as the machine lowers the platform onto the sheet of paper. Use one hand to hold the platform flat and square onto of the paper as you re-tighten the two bolts.

As long as the paper can be pulled out with some resistance your done. Otherwise raise or lower the platform using the onscreen controls and tug at the paper again until you feel the right level of resistance.

The first print I started was the included rook torture test. As this was already on the memory stick I poured some of Elegoo"s own Grey "ABS-like" resin into the tank (after donning on some gloves) up to just below the max fill line after shaking the contents of the bottle carefully. After navigating to the print on the LCD display I selected it, pressed print and away it went.

During the printing the display shows the current curing image being emitted on the print screen, the elapsed and remaining time along with the current layer height.

I think they look fantastic - especially the text on the top of the tower. It is very crisp and legible. I decided to print another print - the Cathédrale Notre-Dame de Paris. The model is detailed and I have one which I had printed on the predecessor to this printer - the Elegoo Mars 2. An ideal comparison for anyone who wants to know if it"s worth making the upgrade.(Again click to see larger images).

It should be mentioned that I have also become more apt at cleaning and curing my resin prints since the model printed on the Mars 2, so bare this in mind when comparing the two. Either way, the improvement in clarity is easily noticeable.

I"ve used the basic version of Chitubox for several models on my Elegoo Mars 2 and I found it perfectly adequate for preparing the models for printing. However, having tried the Pro version it does have some notable and welcome improvements. Here are a few upgrades in usability:

Currently, Chitubox is the only slicer that can prepare files for printing on the Elegoo Mars which is something Elegoo are looking to change. Read more about this here:https://www.elegoo.com/blogs/news/elegoo-official-statement-of-the-chitubox-board-firmware-on-mars-3

Anyone who produces miniatures for painting, or is mostly concerned with very high levels of detail should absolutely be using a resin printer, and I can certainly recommend this one. I hope this equivalent resolution per cm is carried over to the larger Elegoo Saturn range.

Elegoo and other manufacturers do make machines that can both wash and cure your prints for you. This makes the process much easier. As mentioned earlier, they are also working extremely hard to be the first to market with a non-toxic, easy to print and high quality resin. When this has been achieved I"m sure many more people will adopt a resin printer.

The Mars 2 Pro has a 2K resolution (50 µm pixel size), a high-quality aluminum housing, an air filter and very fast layer curing times of 2.5 seconds. With its simple operation and good price-performance ratio, it is also very suitable for beginners.

The fully pre-assembled Elegoo Mars 2 Pro* is packed very efficiently in a small package. It is adequately protected with foam and the accessories are stored in a small extra box.

On all important surfaces like the FEP foil of the resin tank, the touch screen and the print bed are plastic foils as transport protection. They can be removed easily and without leaving any residue.

“Completely pre-assembled” was a bit of a lie – the Mars 2 Pro is 99% pre-assembled: Only the rubber seal needs to be attached to the protective cover.

Elegoo has mounted the print bed with a spring in the ball joint on most of their resin 3D printers. This ensures that the print plate cannot drive too hard into the LCD screen and damage it. But this should not happen anyway, because the Z-zero is already set pretty accurately at delivery and you ensure by leveling that this can not happen in the future.

Aside from this feature, the print bed leveling feature on the Elegoo Mars 2 Pro is very simple, accurate and continuous. Once you have properly leveled the print bed, you can use it to make multiple prints in a row without any problems.

Now you have to adjust the Z zero point: Move the print bed up or down in 0.1 mm steps via the menu. Do this until you can move the piece of paper between the print bed and the LCD screen with some resistance. If this is the case, you can set the Z zero point in the menu.

Optional: You can test with a thin strip of paper if the print bed is skewed. If you can move it between the print bed and the LCD screen more easily on one side than on the other, you need to repeat the alignment. This test is usually not necessary with this well-supported print bed, but I usually do it anyway.

On the supplied USB stick is a test object that you can start directly and without slicing. It has already been sliced by Elegoo and is ready to print.

There is also a predefined profile for the Elegoo Mars 2 Pro*. With this you don’t have to define the 3D printer individually – all settings like print bed size and resolution are inserted automatically.

The first figure I printed with the Elegoo Mars 2 Pro is a very detailed dwarf. His armor and weapons are extremely detailed and have sharp edges and corners. At these sharp points, you can judge the accuracy of the printer particularly well.

The resolution of the 2K LCD screen is 1620 x 2560 pixels. Converted to its print area, this results in an XY resolution of 50 micrometers. This is the standard for 3D printers in its price range.

The Elegoo Mars 2 Pro is basically a Mars Pro with a better LCD screen and larger build volume. But that’s exactly what’s great about it. With about 1.5 times the print volume, you can print much larger models than before!

In the Elegoo Mars 2 Pro is also again an activated carbon filter installed, which catches the harmful vapors of the resin and neutralizes. The rubber seal on the hood helps to ensure that as much air as possible flows through this filter and does not escape from various cracks into the environment.

The Mars, as well as the Mars Pro, feature a build plate measuring 120 x 68 millimeters and a 5.5-inch LCD screen, while the Mars 2 Pro’s build plate measures 130 x 68 millimeters and features a 6-inch screen.

These increases make the Elegoo Mars 2 Pro particularly attractive for you as a user. You also benefit from an increase in the Z-axis height by five millimeters to a total of 160 millimeters. This gives the Mars 2 Pro a third more print volume.

The adhesion of the printing plate was additionally optimized by no longer resorting to a CD-like concentric texture as before, but the new printing bed was made of a coarse, sandblasted material. In general, however, the 3D printers from the company Elegoo are known for their particularly convincing adhesion of the printing plate.

The monochrome LCD has transformative properties. These can be attributed in part to the underlying light source. While the Elegoo Mars Pro used an optimized illumination system to provide improvements in curing times compared to the Mars, the Mars 2 Pro uses an even more powerful light source.

The Mars 2 Pro is equipped with a 6-inch LCD with 2560 x 1620 pixels. There are similarly sized 3D printers, which also have LCDs and convince with a 4K resolution. These offer XY resolutions in the range of 30 micrometers.

Compared to its predecessor, the Mars Pro’s print time has been reduced by about eight percent due to the realigned light engine. The Mars 2 Pro reduces this time by a further 38 percent. While the Mars 2 Pro takes about one hour and 40 minutes to print, the Mars and Mars Pro take more than two hours and 40 minutes to print the same project.

Probably the most significant improvement to the Mars 2 Pro is the addition of a monochrome LCD. This extension allows a greater intensity of UV light to pass through and thus ensures that the photopolymer resin can solidify more quickly. In this way, the device achieves particularly short layer curing times. While a non-mono printer averages around six seconds, a resin printer with a mono LCD achieves cure times of just one to two seconds.

The Mars 2 Pro has a larger print volume, a higher resolution LCD screen and a larger print area overall. So with the Mars 2 Pro, you can print larger objects than with the Mars Pro.

The only disadvantage of the Elegoo Mars 2 Pro compared to the Mars Pro is a slightly worse XY resolution. It is 3 µm smaller. However, this is neither measurable nor visible and should not influence your purchase decision.

This smaller resolution is due to the larger print area, resulting in a slightly smaller XY resolution despite the higher resolution of the LCD screen.

When the Elegoo Mars appeared on the market, it was praised by numerous supporters of 3D printing. Not only the relatively affordable price and its excellent printing performance are convincing, but also the all-around simple operation, which makes the Mars a suitable device even for beginners.

While the Elegoo Mars Pro remains one of the most advanced resin 3D printers, the manufacturer has managed to surpass even this great printer model. While the Mars Pro builds on the technology of the original Mars, offering additional enhancements, an improved print plate, and new file compatibility, the Mars 2 Pro builds even further on it, adding a monochrome LCD to all of these positive features, promising users shorter layer cure times.

But what exactly are the differences between these three devices and are the price differences justified or can you as a user just as easily opt for the original Elegoo Mars?

The main differences between the Elegoo Mars, the Elegoo Mars Pro and the Elegoo Mars 2 Pro lie primarily in the special features and measures that the manufacturer has taken to further optimize the original Mars.

Elegoo saw an opportunity to improve the original Mars light engine even further and so decided to upgrade from a 40 watt UV LED to a more powerful model for the Mars Pro. In application, this increase in light intensity means that, assuming Elegoo resin is being used, the Elegoo Mars Pro is slightly faster than the Elegoo Mars, which has a layer cure time of six seconds per layer, compared to eight seconds.

What clearly sets the Mars 2 Pro apart, however, is its monochrome LCD, which allows a greater intensity of UV light to pass through. In this way, the curing times of the individual layers are accelerated to one to two seconds per layer. An additional advantage of the monochrome LCD is also the significantly longer service life.

Both the Mars and Mars Pro offer reliable stability due to their movement on the Z-axis. Nevertheless, Elegoo took the opportunity to improve the Mars Pro and Mars 2 Pro even further and retooled the units to use a linear guide as opposed to grooved wheels. On the original Mars, these run along dual extrusions.

The first model of the Elegoo Mars does not have an air filter unit. In contrast, the Mars Pro and the Mars 2 Pro are equipped with a carbon filter system. In the Mars Pro, this is located in the base unit of the printer and ensures that the unpleasant odor that arises when working with exposed resin is neutralized.

However, since you have to open the device anyway, for example, to remove the prints, change the resin or clean the entire printer, the smell will still be released. If you basically make sure that the 3D printer is located in a well-ventilated room, you will achieve almost the same effect as with an air filter. However, the carbon filter included in the Mars Pro and Mars 2 Pro is an overall improvement, even if it is only minor.

Another point about ventilation is the rubber gasket that was placed around the protective cover on both the Mars Pro and the Mars 2 Pro. The protective cover of the original Mars was placed in the recess at the edge of the printer, which again allowed annoying odors to escape.

Shortly after the original Mars printer was released, an inexpensive set of replacement resin containers from Elegoo appeared on the market. These are optional containers made from injection-molded plastic which, due to their significantly increased filling volume, offer a major advantage over the metal container included as standard with the Mars printer.

A larger fill volume gives you longer printing between refills of the tank and shortens the time you have to work with exposed resin. For the Mars Pro and Mars 2 Pro, this replacement tank has been reinforced with a metal equivalent, which in turn provides an even larger volume.

The printing plate mounted on the original Elegoo Mars was already of good quality, but the manufacturer has optimized it again on the Mars Pro and Mars 2 Pro. The plate surface of the Mars Pro has a grippy radial effect thanks to large screws to facilitate print bed alignment.

This also guarantees even better adhesion. With the Mars 2 Pro, however, Elegoo has again decided to use the sandblasted texture of the printing plate already known from the Mars, as this has greater adhesion than the structured print bed. However, experience has shown that there is no noticeable difference between the two textures.

The Elegoo Mars was often criticized for the unfavorable position of the USB port. It is located on the back of the original device. Since you as a user often blindly try to connect to the port, it wears out very quickly.

The Mars Pro has therefore been improved in that the USB port has been moved from the back of the device to the center of the front, making it much easier to reach. This adjustment is only a small change, but is perceived as a big improvement in the usability of the device and has thus been adopted for the Mars 2 Pro as well.

An often under-appreciated difference between the Elegoo Mars, Mars Pro, and Mars 2 Pro is their compatibility with different file types that ChiTuBox slicing software works with. While the Mars, similar to many other low-end desktop MSLA 3D printers, works with Chitu’s older .cbddlp file extension, the Mars Pro as well as the Mars 2 Pro benefit from ChiTuBox’s newer .ctb file type.

There are no significant differences in print quality between the Elegoo Mars and the Elegoo Mars Pro. The resolutions used are the same, so any difference can only be caused by external factors. These include, for example, the temperature of the resin, incorrectly made print settings or the orientation of the 3D print model.

However, the new Elegoo Mars 2 Pro has a slightly lower resolution. The reason for this is its 2560 x 1620 pixel panel, which contains more pixels than the predecessor models from a technical point of view, but they also have to be distributed over a larger surface area. Thus, the pixel density is reduced.

Since the Mars Pro is based on the Mars and has only been equipped with useful improvements, it is comparatively the better choice. Some often criticized features have been optimized and new surprising upgrades have been added, which definitely justifies the slight price jump.

However, when comparing the Mars 2 Pro, which is available for a slightly higher price than the Mars Pro, it is the clear winner. Not only does it offer the same improvement in user-friendliness, but it also convinces with its monochrome LCD panel, which not only provides the user with shorter curing times of the layers but also increases the longevity of the device at the same time. Another convincing advantage is its slightly increased build volume.

If you already own the original Mars model, there’s no need to upgrade to the Mars Pro, as the print quality is identical and you’d only be paying a premium for the minor usability improvements. If you are still a beginner to 3D printing, any model in the Mars series is a good choice. However, from a price perspective, it makes sense for you to opt for the Mars 2 Pro in this case. Its available upgrades are worth the slightly higher price, and this way you’re guaranteed to benefit from a smooth and fast printing experience in the future.

It has established itself as a very popular model and is one of Elegoo’s best sellers. You can’t go wrong with this 3D printer – it’s one of the best!

The Elegoo Mars Pro* is the further development of the successful basic model and is now available for a very small price. It has an XY resolution of 47 µm and in Z direction of 1.25 µm. Its print volume is 115 x 65 x 150 mm and is very beginner-friendly.

The Phrozen Sonic Mini 4K* is one of the most accurate resin 3D printers in its price range. With the fast monochrome LCD screen and the 35 µm XY resolution, even the smallest details can be seen. The print volume is 132 x 74 x 130 mm.

The Elegoo Mars 3* has a 4K resolution (4098 x 2560). With a print area of 143 x 90 mm, it achieves an XY resolution of 35 µm. The ratio of printer size and print volume is very good.

Elegoo is an incredibly popular 3D printer manufacturer that’s known for producing a variety of budget-friendly resin 3D printers, making 3D printing accessible and enjoyable for many.

The company has recently launched the Elegoo Mars 3, which packs in an interesting number of new, cutting-edge features and a price tag of around $400, which fairly falls in the budget range.

This latest addition to Elegoo’s Mars series of resin 3D printers comes after the Elegoo Mars 2 Pro and includes many upgrades, such as a 4K LCD screen and a different design.

The Elegoo Mars 3 looks very promising as a 3D printer, but looks can often be deceiving. Therefore, I decided to write a review article so you can determine if this unit is worth buying or not.

This review will go through the features, specifications, benefits, downsides, and customer reviews of the Elegoo Mars 3, so follow along to figure out whether this MSLA 3D printer is the one for you.

The Elegoo Mars 3 boasts a brand-new design with a professional-grade appearance. The manufacturer has tried to do something different with this unit design-wise and has ended up creating a more rounded and ergonomic look.

This is a step up from the usual boxy design of the Elegoo Mars series, which, to be fair, doesn’t look too bad. However, the upgraded, industrial-grade design of the Mars 3 is a breath of fresh air and a huge aesthetic improvement.

In addition to that, the printer is fairly sturdy and firm, which paves the way to a more stable 3D printing experience. If nothing else, you will really appreciate how stunning the Mars 3 looks.

One of the most exciting new features of the Elegoo Mars 3 is its 4K monochrome screen, which is definitely a decent improvement over the Elegoo Mars 2’s 2K LCD screen.

Purchasing this SLA machine, you can expect your parts to come out with exceptionally high details and clarity. The 4K monochrome screen makes it possible for the Mars 3 to print at a resolution of 35 microns compared to the Mars 2’s 50-micron resolution.

One of the best benefits of the 4K monochrome screen is the fast curing time of 1.5-3 seconds. This allows you to make 3D printed objects quicker while making sure they’re of high quality.

The Elegoo Mars 3 is made more accurate than any of its predecessors. The manufacturer says that there’s a cool 30% improvement in printing accuracy as compared to the Mars 2 that makes the prints appear sharper than ever.

Elegoo has decided to switch things up with the Mars 3 design-wise by giving it a different and more stylish look than before. It occupies a small footprint and measures 227 x 227 x 438.5mm dimensionally.

The Elegoo Mars 3 has a large build volume that measures 143 x 89.6 x 175mm dimensionally. It is also slightly larger than the build volume of the Elegoo Mars 2 Pro.

If you constantly feel the need to make multiple small parts in one go, the added capacity of the Mars 3’s build volume will fit your requirement perfectly and open up more possibilities for 3D printing.

The Elegoo Mars 3 uses a powerful COB (Chip On Board) light source with an XY resolution of 0.035mm (4098 x 2560 pixels). When such a high-end component is being used on the printer, it’s logical to worry about heating issues.

To accommodate this worry, the Mars 3 has received an improved heat sink upgrade which dissipates heat 50% more efficiently than ordinary heat sink systems.

The Elegoo Mars 3’s sandblasted build plate brings the benefit of top-notch adhesion for your 3D models. Poor adhesion can cause multiple print issues, but that is definitely not the case with this high-quality 3D printer.

The solid linear rail that moves the build platform up and down on the Elegoo Mars 3 feels firm and sturdy. It allows the printer to operate with great stability, making your prints turn out smooth and clear with almost zero layer lines.

The upgraded FEP film 2.0 does a great job at making the Elegoo Mars 3 perform better than ever and make the prints adhere to the sandblasted build plate efficiently.

The FEP film 2.0 of the Elegoo Mars 3 is thinner than the FEP film of the Mars 2. The extra thinness can actually help the models stick nicely to the build plate and prevent them from gripping the resin vat.

Customers who have bought the Elegoo Mars 3 from all around the world couldn’t be happier with their purchase. This printer has raised the bar for budget-range resin 3D printers, as many still can’t believe how low it costs for the number of features it has.

One person writes that the inclusion of a 4K monochrome screen made all the difference in the world for them. They were able to achieve details of prints that weren’t possible with their previous SLA 3D printers.

Another experienced customer loves the large build volume of the Elegoo Mars 3 and says that this enables makers to make their creativity come to life and make bigger models painlessly.

It’s also well admired that the Elegoo Mars 3 has a fast printing speed. A single cured layer of resin can take about 1.5-3 seconds to print, making rapid prototyping possible for expert 3D printer users.

This is smart thinking by Elegoo – giving the first year free of the ChiTuBox Pro Slicer and letting its consumers enjoy high-end features like auto-repair and orientation, so they can be convinced to purchase the slicer on an annual basis.

The Elegoo Mars 3’s new rounded design is also a plus point that several customers have loved. Accompanying this feature is the unit’s rigidity and stability that paves the way to a smooth printing experience without any wobbling.

One user pointed out that a lack of Wi-Fi functionality is still a bothersome affair. This could be addressed further down the road with an Elegoo Mars 3 Pro version, but for now, we will have to settle with USB connectivity only on what is otherwise a brilliant resin 3D printer.

The Elegoo Mars 3 is quite possibly the most efficient MSLA 3D printing in the world right now, all thanks to its 4K resolution screen, large build volume, and a slick new design.

It’s a simple plug-and-play machine that demands no additional effort from your side. You just purchase it, set it up within 10-20 minutes, and get to making high-quality 3D prints in no time. This makes the Elegoo Mars 3 highly desirable for beginners and professionals alike.

If you’re after a resin 3D printer that works reliably, has a load of features, creates stunningly detailed parts at fast speeds, and also doesn’t cost a fortune, then the Elegoo Mars 3 is definitely the 3D printer built for you.
