Unboxing Experience of the Elegoo Mars 2 Pro

Elegoo have plenty of experience with packaging their resin 3D printers, so it was no surprise that the unboxing experience was very pleasant with the Elegoo Mars 2 Pro.

The printer was smaller than I expected but still provides a good amount of build volume while not taking up too much space.

Leveling Process for the Elegoo Mars 2 Pro

The leveling process for the Elegoo Mars 2 Pro is pretty simple like most resin 3D printers. It has two main screws that require the larger Allen key in the tool kit. You want to slightly loosen the two screws and lower the build plate by going to “Manual” and pressing the Home icon.

Get a piece of paper to use as a leveling guide and place it under the build plate after lifting it up using the touchscreen buttons.

You want it to have a fairly tight grip on the paper but still be able to wiggle a little bit.

Raise up your build plate, slide the resin vat in and lock it in place with the two thumbscrews on the sides.

You can now fill the resin tank up, ensuring it doesn’t go above the “MAX” level. I’d recommend lifting the build plate to a good height so it’s easier to pour.

Don’t forget to put the silicone rubber seal on the lid!

I’d say the test was a success, let’s continue printing.

Large Batman Model

I tried printing this model once before and had the print coming off the build plate, most likely due to the supports. I re-supported the model with thicker supports and tried again.

You can see them kind of separating a little but it still worked out nicely.

Dobby

This one came out really nice.

Rose with Stem

I printed one of these on my Ender 3 so I decided to try it out with a resin printer.

Mission successful. I ended up giving this to my mother and she loved it!

Superman

You know we can’t just put Batman in there without throwing in Superman.

The supports holding up the lowest point of this model failed because there weren’t enough supports, but I still managed to have this one come out somewhat succesfully.

Buddha

Now this one was a special request from a friend. I hadn’t yet tried mixing Clear resin with dye but wow did it come out great.

Elegoo Mars 2 Pro Review - Purple Buddha 1 - 3D Printerly Elegoo Mars 2 Pro Review - Purple Buddha - 3D Printerly

Here is exactly what I used to create this unique color. It was mostly the purple color at probably a 4:1 ratio of purple to purplish red.

Ornamental Squirtle

I did this print right after the Buddha print as you can see from the purple feet and tail. I wanted to do a gradual change over but I just ended up doing a color change.

You can see where I mixed in the clear resin and let that print for many layers before adding the blue. I like that it’s a really unique model.

That’s the end of the print quality with the Elegoo Mars 2 Pro, a serious machine! Let’s get into the rest of the details.

Features of the Elegoo Mars 2 Pro

  • 6.08″ 2K Monochrome LCD
  • CNC-Machined Aluminum Body
  • Sanded Aluminum Build Plate
  • Light & Compact Resin Vat
  • Built-In Active Carbon
  • COB UV LED Light Source
  • ChiTuBox Slicer
  • Multi-Language Interface

6.08″ 2K Monochrome LCD

The Elegoo Mars 2 Pro MSLA 3D Printer comes with a 6.08-inch Monochrome LCD that has 2K HD resolution. It is four times longer in lifespan and two times faster in printing speed than the regular RGB LCD 3D printers, which means higher printing efficiency, more stable performance, and less maintenance.

CNC-Machined Aluminum Body

Unlike other plastic printers you may find on the market, Mars 2 Pro is made of CNC machined aluminum from build platform to resin vat. It has a very solid build quality and high durability like a reliable workhorse that always gets its work done.

It also has a linear guide rail for consistent steady and accurate motion throughout the printing process

Sanded Aluminum Build Plate

The build plate has been sanded to create a stronger adhesion between the cured resin and the surface. When you compare this to some older models of resin 3D printers, you’ll be sure to get a much higher success rate for printing your models.

On top of this, I’d also advise to use a PTFE spray or lubricant on your FEP film to prevent your resin sticking to the bottom rather than the build plate.

Light & Compact Resin Vat

The vat has been remodeled in a way that makes the experience just a little better for the average user. It is made of an aluminum alloy and has a beautiful light and compact design.

Many people will appreciate the “Max” line that is on the side of the vat to give a warning level where you can fill resin to and print safely, without it spilling over the sides.

Built-In Active Carbon

The Elegoo Mars 2 Pro comes with built-in active carbon. Built-in activated carbon could absorb the fume of resin. Working together with the turbo cooling fan and silicone rubber seal, you can barely smell any irritant odor, giving you a seamless printing experience.

COB UV LED Light Source

Excellent heat dissipation performance, high luminous maintenance rate, uniform light emission, and no spots. COB light source has proved itself to be a fantastic upgrade that ensures each printing comes out perfectly.

ChiTuBox Slicer

ChiTuBox has been a very helpful companion when you are using Elegoo MSLA resin 3D printers from slicing .stl file to adding supports. With the latest 8-times anti-aliasing function, you can get a much smoother printing surface.

In general, it’s a very capable resin print slicer with all the functionality you want.

Multi-Language Interface

The new operating system now supports 13 different languages: Chinese, English, Japanese, Dutch, Korean, French, German, Russian, Italian, Spanish, Turkish, and Portuguese, which significantly facilitates worldwide users to use Mars 2 Pro more conveniently.

Customer Reviews of the Elegoo Mars 2 Pro

The Elegoo Mars 2 Pro Mono MSLA 3D Printer has gathered stellar reviews from around the globe, with users going as far as calling the 3D printer revolutionary in the resin printing arena.

Several users were amazed by the outstanding print quality the Mars 2 Pro offers. The amount of detail and finish is top-notch. You can easily call it as the star feature of the 3D printer.

The Mars 2 Pro comes with an easy set-up and leveling process coupled with fairly optimal default settings. You will seldom feel the need to tweak them.

One user found the build of excellent quality with the metal resin tank and printer body. The Z-axis motor and materials are all fantastic and look highly durable as well.

An additional quality that the Mars 2 Pro boasts of is the inclusion of an angled plate holder, which lets post-print excess resin safely drip back into the vat.

Based on the customer reviews, a problem that was criticized by many was that the base of the model adheres to the printing plate and is very difficult to remove. It gets tough to extract the prints off the build plate without breaking them.

A user states that the XY resolution is 50 microns, compared to 47 microns on the Mars Pro. That small of a difference shouldn’t be visible, but it’s still worth noting.

A couple of users mentioned working with the ChiTuBox Slicing Software as a little complicated. In addition to this, the monochrome LCD appears to lack a protective glass, causing issues for some, with reports of the display scratching easily.

But the Elegoo Mars 2 Pro does, in fact, have a replaceable LCD screen lest it get damaged. That, and the lower pixel resolution, are the only downsides to an otherwise superb printer.

Verdict – Elegoo Mars 2 Pro Worth Buying or Not?

The Elegoo Mars 2 Pro Mono MSLA 3D Printer is described as revolutionary by the users in the resin printing arena. We have come across strong testimonials to support this statement.

With a monochrome screen, an increased build volume, and incredible print quality, the Mars 2 Pro has made a mark for itself in the industry. Printing with the Elegoo Mars 2 Pro is straightforward.

The machine is virtually plug-and-play, making it an optimal choice for creators. The Mars 2 Pro is the logical progression of the Mars series of printers.

The monochrome LCD dramatically shortens printing time over its predecessors, which, combined with the leap in print volume, is a compelling reason for you to go ahead and buy it.

If you want a great printer that balances speed and quality, the Mars 2 Pro is a worthy choice. For newcomers that don’t already have a resin printer, the Mars 2 Pro is a splendid buy.

The appeal of the Elegoo Mars 2 Pro (Amazon) with its reputed quality and ease of use makes it a great choice for novices and professionals alike.
