LCD Screen: The screen thickness is 0.55mm.Compatible for Creality LD002R / ELEGOO Mars /Anycubic photon 3D Printer. (Note: Not compatible for Elegoo Mars Pro.)

Ultra 4K 6.6-inch monochrome LCD with a high resolution of 4098*2560, which greatly improves the printing accuracy and makes your model details better.

Compared with ordinary 2K LCD 3D printers, its printing volume is 37% higher than that of Mars 2, which breaks through the limitations of Mars 2 printing and realizes greater imagination.

The XY accuracy is as high as 35 microns, which is 30% higher than the Mars2 series, with higher printing efficiency, more stable performance and less maintenance.

The LCD used for printing on Elegoo Mars is RGB – there are three subpixels – red, green and blue. Since the backlight LED produces a quite narrow range of wavelengths (peaking around 405nm), only the blue filter passes the light. That means that 2/3 of the backlight power is wasted to the LCD. Also, it means that only 1/3 of the pixel is exposed and the rest is hardened only via exposure bleeding – the effect we, on one hand, want to eliminate, on the other hand, it is essential for properly working screen. Aftermy modification, which removed the protective glass, you can see on my prints under a microscope the effect I mentioned – 1/3 of the voxel is nice and sharp, the remaining 2/3 are smudgy.

There were recently announced printers with monochromatic LCD. They feature low exposure times (around 2 seconds) with less power than Elegoo Mars. However, their LCDs have poor resolution.

First, I examined the LCD. I figured out that the two most outer layers are the polarizer. They are not glued, they hold similarly like to protective glass. Then there is a bottom plastic film with the pixel electrodes (I am sorry for not providing pictures, however, I was not able to take them from the microscope). Then there is a glass layer – on one side (the top side) it is covered by ITO – a conductive clear coating. On the bottom side, there is a layer of color filters. Between the glass and plastic film is a layer of liquid crystals, more specifically between the plastic film and the filters.

Having experiences with disassembling LCDs before, I know how to separate the glass from the plastic film. Just use a fresh Xacto knife and slide it between the layers, move along the perimeter and the layers separate:

You can see that the glass got much more transparent. Then I cleaned it properly and put the LCD back together. Unfortunately, I was not careful enough and I got some dust particles to the crystals. Therefore, I got polarizing patterns on the LCD:

So – it is possible to do! To fix the issue, I separated the layers again, cleaned them both with IPA using a paper towel, put liquid crystals I harvested from an old computer screen between them. I got LCD without dust particles, but with strange, colorful, patterns:

To do more experiments, I am looking for screen donors – I look for people willing to send me their LCDs with dead pixels. Doing these experiments on brand new displays seems to be wasteful to me. So if you have such a display and you live in Europe, please contact me!

All Elegoo 3D Printers have cULus Certified (CSA Approved) certification marked on back of each unit or on the power supply directly. This mark is accepted by all electrical regulatory authorities in Canada.

6.6-inch 4K monochrome LCD screen with a replaceable anti-scratch tempered glass with 9H hardness for a better light transmittance at 4098 x 2560 high resolution, protecting the screen while restoring model details to the greatest extent.

ELEGOO Mars 3 Pro comes with a 6.6 inches 4K mono LCD screen with a resolution of 4098 x 2560 and an XY resolution of 35μm, providing prints with fine details and high precision, which far surpasses FDM printers in quality and speed.

In addition, there is a replaceable scratch-resistant tempered glass above the LCD screen with a perfect fit for better light transmission and protection.

Upgraded COB UV LED light source with 36 highly integrated LED lights perfectly matches with Fresnel lens, ensuring the light intensity distribution across the entire screen uniform with consistent accuracy.

The vast majority of consumer 3D printers on the market today utilize the fused-filament fabrication (FFF) printing process, because it is affordable, reliable, and efficient. But, thanks to rapidly lowering printer prices, resin 3D printers have started to gain serious traction in recent years. While FFF 3D printers are still the better option for most people, resin 3D printers are usually capable of printing finer details and are ideal for small models like figurines. The Elegoo Mars is one of the most popular resin 3D printers at the budget end of the market. Jan Mrázek has been working tirelessly on mods for the Elegoo Mars, and hasa new guide on how to dramatically improve the performance with an LED array retrofit.

Most budget resin3D printers, includingthe Elegoo Mars, cure the photosensitive resin in layers using UV light that is masked by an LCD screen. The resulting quality isn’t quite as good a traditional laser stereolithography, but it is more affordable and less delicate.LCD screensthemselves are transparent, and resin printers like the Elegoo Mars simply turn on black pixels that act like shutters to only allow UV light through where the layer needs to be cured. That light comes from an array of UV LEDs, which is what this modification focuses on. The theory is simple: increase the power output of the LEDs and you reduce the time needed to cure the resin. Each layer is printed more quickly and the total time to complete a part is lowered. In this case, Mrázek claims a 3-4x speed increase as well as an improvement to precision.

The obvious question is “why didn’t Elegoo just do this themselves?” The answer is cost savings. These LEDs are more expensive, require a beefier power supply, and get hot, which necessitates the use of additional cooling. But, if you’re willing to spend the money for this mod, it should be worth your while. The new array contains 28 individual UV LEDs. Those are backed by a massive heat sink with a pair of fans for cooling. To avoid light bleed and improve precision, Mrázek 3D-printed special lenses for each LED that contain the spread of light as much as possible. Mrázek was able to get the layer cure time down to just one second, but the heat eventually caused his LCD to fail. He was forced to reduce the LED power output by half, but this is still far better than the original LED array’s output and allows for much faster printing.

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.
