Elegoo Mars 2 Pro Review: The Elegoo Mars 2 Pro is Elegoo’s extraordinary parley into the realm of resin printers for the desktop. Elegoo’s latest printer model keeps up with monochrome LCDs, which may become the new standard in affordable resin printing

Because of the quick layer cure times, the newer technology enables machines to print faster. This is in comparison to non-mono printers.

The Elegoo Mars 2 Pro features an aluminum enclosure, an air filter, and a quicker 2.5-second layer curing period. Coupled with a 2K resolution of 50 m pixel makes this printer simply out of the world for printing miniature models.

It is also ideally suited for starters due to its simplicity and value for money offering.

Setting Up Mars 2 pro

Though it is advertised as completely assembled, the machine is a whisker away from being fully assembled. Finally, attach the rubber seal to the protective cover.

To minimize any chances of exposure to light or escaping of vapors, pay attention to the rubber seal. 

Mount the print bed on the Z-axis using the big turning screw from above and complete the setup.

There is a tiny recess in the housing for the resin tank. This makes aligning it simple and keeps it from slipping.  Do this after the printing plate is properly positioned and leveled.

Packing List and Delivery Scope

The Elegoo Mars 2 Pro comes assembled and packaged in a foam-protected compact package. The accessories come bundled in a smaller box. Everything one needs for printing is packed, which is awesome. 

Yet, Isopropyl alcohol, UV resin and paper towels are missing from the packing list. It is suggested to purchase the Eco Resin from Anycubic as it is safer (less toxic) than available from other sources. 

There is a USB stick which contains the manual (digital copy), ChiTuBox slicer application and a test print.

Plastic foils are employed for transport protection on all key surfaces, such as the FEP foil of the resin tank, the print bed, and the touch screen. One can remove them leaving no residue.

The delivery scope is detailed as follows: 

  • Assembled printer
  • Protective cover (red in color and transparent) + rubber seal
  • Print Bed
  • Resin tank
  • Draining device
  • A  Power cable
  • Spatula (Metallic) useful for unhooking  objects from the print bed
  • Scraper (Plastic) for removing FEP foil residues from resin tank
  • Side cutter
  • Resin filter (made of paper)
  • Gloves and Masks
  • FEP film (replacement)
  • Toolset
  • USB drive (user manual, ChiTuBox App and test print)

The Elegoo Mars 2 Pro is a step forward, but not a huge one, with a monochrome screen and larger construction volume. 

Today, mono LCD printers come in many forms and sizes, and the Elegoo Mars 2 Pro is no exception in terms of print resolution or capacity. 

Yet, the Elegoo Mars 2 Pro excels over others due to its excellent quality and ease of use. 

Elegoo Mars 2 Pro Review: Is It Really Worth It?

The Elegoo Mars 2 Pro is the next step in the Mars printer series. The monochrome LCD cuts printing time in half compared to its predecessors. Combining this with the increased print volume, there is a strong incentive to buy the Mars 2 Pro.

Although the printer is not earth-shattering by any sense of the word, the trademark Mars quality and ease of use put in some weight.

At $300 the Elegoo Mars 2 Pro may not be the cheapest mono-LCD printer, or an eye-popping bargain, but it’s still clearly one of the decent ones around.

Salient Features

Let’s look at the features of this amazing mono-LCD printer:

LCD Resolution

The Elegoo Mars 2 Pro has a somewhat lesser resolution than its earlier version, the Mars Pro, despite having a 2K LCD as part of its curing engine.  

The printer’s 1620 x 2560 pixel screen while specification wise is finer in resolution, the spread is over a greater construction area.  This reduces pixel density with an XY resolution of 50 microns. The Mars Pro XY resolution in comparison was 47 microns.

Curing Speed

The incorporation of a monochrome LCD is a new feature of the Elegoo Mars 2 Pro. This is used for the masking sage in the printing process. 

This component enables the printer to achieve short layer cure times by allowing a higher intensity of UV light to pass through. 

This sparks the reaction that causes photopolymer resin to harden faster. Thus a mono-LCD-equipped resin printer may achieve cure times of one to two seconds, compared to six or more seconds for non-mono printers.

Aside from speed, monochrome LCDs have a longer lifespan, often in the thousands rather than hundreds of hours.

Elegoo Mars 2 Pro Build Volume

The Mars 2 Pro will have a construction volume of 129 x 80 x 160 mm. This is a little bigger than that of the Mars Pro. The Mars 2 Pro has a greater build volume than the Anycubic Photon S, which it outperforms.

Firmware / Software

The Mars 2 Pro utilizes the ChiTuBox firmware and application software.  This usually results in a printer that’s straightforward to operate. 

The software’s automation capabilities do a good job of automating support generation and other tasks. Yet, one can also go manual and fine-tune printouts as needed.

Compact Design

The Mars 2 Pro design is not much different from the Mars Pro, albeit with the addition of a new LCD. 

Owners of the Mars Pro will be already familiar with the build plate and plate leveling. Yet, with a linear rail guiding the Z-axis movement and Elegoo’s big capacity resin vat, the build also lacks any new updates.

One can locate the USB port on the printer’s front face. This offers a wonderful convenience, and the Mars 2 Pro also includes a carbon air filtration device inside the print chamber.

Lacking 4K?

A resolution boost to 4K is absent from the Mars 2 Pro. The inclusion of 4K was to be a standard in future models, to take on businesses like Phrozen releasing a low-cost 4K mono printer.

The Mars Pro is still a fantastic printer, with many enhancements, and with a significant speed bump. Yet, the Mars series of printers will remain behind the curve, if they keep churning out printers employing 2K LCDs.

Activated Carbon Filter

The activated carbon filter inserted in the printer’s back base is making a comeback on the new Mars. It is noble that the printer has reduced the emission of VOCs by the resin.

The rubber seal on the cover ensures that most of the toxic air passes through the filter and does not leak through various vents or cracks.

Yet, after a few months, filters do wear out, and changing them on Mars Pro doesn’t appear to be too simple.

Draining off Resin

The print bed is entirely submerged in resin throughout the first section of the print. The print bed is beveled on the top to allow the resin to drain. Because much of the resin has already dripped off the print bed, cleaning up after printing is much easier.

A drip device for the print bed is also included. After printing, gently remove the print bed, put the drip device on the Z-axis, and hang the print bed at an angle on it. 

Most of the resin will have dropped off the print bed after a few minutes. Do remember to replace the hood afterward.

Print Plate Adhesion 

Printing plate adhesion was also improved by not using a side-by-side like texture. Instead, the Mars Pro has opted for a coarse, sandblasted material for the new printing bed.

Transformative LCD

With the introduction of monochrome LCDs there is a transformative experience. The Mars Pro employs both, a better illumination system to enhance curing times, and an even more intense light source.

Instead of the LED matrix used before, a single strong UV lamp with a lens now evenly distributes light across the whole print bed surface. The Elegoo Mars 2 Pro has a 6-inch LCD with a resolution of 2560 x 1620 pixels for the XY-Axis. Monochrome LCDs also last longer from hundreds to thousands of hours.

Short Printing Queue 

Because of the repositioned light engine, there is a reduction in print time with the Mars Pro. It is around 8% less when compared to its predecessor. The Elegoo Mars 2 Pro cuts this time down by another 38%. 

The Elegoo Mars 2 Pro takes roughly less than 2 hours to print the identical product, whereas the Mars and Mars Pro take almost 3 hours.

Front Side USB Port

The USB slot is now located on the front of the printer, which is very small. This is especially useful if one is setting up the printer with limited space on the left and right. Without having to understand how to accommodate the USB drive.

Elegoo Mars 2 Pro Review: Quality of Print Output

The Elegoo Mars 2 Pro produces great prints, better than most other 3D printers.

There were a few exceptions with some tiny features which may bend depending on the orientation of the printer.

Still, this printer did a great job of replicating all but the minor details. Overhangs and Bridges came out quite well with the right support and angle, avoiding the creation of islands.

The chess rooks’ spirals and steps have incredibly smooth curves and great surface polish. It can also print a near-perfect Eiffel Structure, with even the tiniest details towards the top of the tower showing up in the print.


Resin printers produce intricate prints as compared to FDM printers. Yet, they are notoriously difficult to run, and the Elegoo Mars 2 Pro is no exception. 

When employing resin printers, the biggest challenge is the resin itself. If there’s a danger the resin will come into touch with your skin, one should wear gloves. 

It also tends to make a mess, making switching resins considerably more difficult. Then, one has to filter the resin inside the container, and then clear the vat — with isopropyl alcohol — before swapping in a fresh color.

Thankfully, the Elegoo Mars 2 Pro doesn’t take any setup or assembly and is ready to use right out of the box. It is far easier to balance the build plate. One has to normally release the screw, separate the Z-axis from the screen with some paper, then fasten the screw and fix the height for the Z-axis.

Files are uploaded to the Elegoo Mars 2 Pro via the USB drive, and the screen displays basic information about the print’s status while it’s running. 

One has to still deal with the entire cleanup and other responsibilities that resin printing entails. 

After removing a print from the machine, one has to remove any supports and completely wash off any uncured resin on the model before disposing it off. 

Before the print completion, one has to use UV light to post-cure the resin – with sunlight or using a UV-light chamber. Isopropyl alcohol, gloves, toothbrushes, paper towels, filters, and UV lights are required for this.

Printing Capability

Most users use the ChiTuBox slicer application with this printer. There are a few alternative slicers out there, but you’ll have fewer options than with an FDM printer. 

This printer’s build volume is a little on the lower side, measuring 130mm x 80mm x 160mm.

The stock build plate performs well with a variety of resins. This printer is also material-agnostic, working with any 405 nm resin, whether Elegoo-made or third-party.
