elegoo mars replacement lcd screen made in china

The original ELEGOO Mars and Mars pro come with the Sharp04 screen, which is 5.5 inches 2K RGB LCD, since 2018 there are Mono LCD coming out, and it is been widely used during 2019, the Phrozen sonic Mini, Anycubic Photon mono series, and ELEGOO mars 2 series. we also write an article about RGB vs Mono, you can check here.

One word of warning though. The LCD screen is mounted onto a glass sub-screen. Initially I removed both the LCD and glass screen as a single unit. Fortunately they are only held in position with double sided tape. The actual LCD screen is only about 3 mm thick and they advise you to use a hair dryer as a heat source to soften the adhesive. Something I wish I had done.

I"ve now gone and got me a mono LCD Mars 2 machine as well as the Mars 2 Pro as it also has the same mono LCD screen and build plate as the Pro so it will be interesting to compare results.

I just finished printing 2 tall tubular pieces for a Star Wars blaster on my Mars 2 pro, and when I went to check on it the last few layers were very irregular. After removing the piece I started to pull out the resin tank for cleaning and noted that it was stuck a bit to the LCD screen. I was able to get the resin tank out, but now realized that the FEP screen had gotten damaged during printing and some resin had leaked out and cured to the LCD screen in two thin circles.

After wiping up the resin I used a razor blade tool (for cleaning glass stove tops) to try and gently scrape the circles off the screen. As I scraped and very gently pried at the circles, I noticed that they were pulling up what looked like a plastic layer that was on top of the LCD.

I went on Elegoo"s website and looked at the video for LCD screen replacement. It shows a person removing 2 plastic layers before installing the new screen.

Although Elegoo isn"t the only resin 3D printer manufacturer on the market, it"s certainly one of the most popular. Consistently, Elegoo offers low-cost 3D printers that, despite affordable price tags, boast incredible print quality. When I first tested out the Elegoo Mars, I was extremely impressed. And its Elegoo Mars Pro added a slew of improvements for an even better printing experience. Now, Elegoo provides its Elegoo Mars 2 Pro. But should you buy it? Learn all about the Elegoo Mars 2 Pro resin 3D printer in our review!

At a first glance, the Elegoo Mars 2 Pro remains largely unchanged from its predecessor, the vanilla Mars Pro. But the Mars 2 Pro sports a few key differences. Its 2K LCD screen features a slightly lower resolution than the Mars Pro, with a 1620 x 2560 panel. Although higher than the resolution of the Mars Pro LCD curing screen, it"s spread across a bigger build area so that its pixel density is slightly reduced. 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.

Aside from resolution and pixel density, the Elegoo Mars 2 Pro touts a monochrome LCD for masking. Because more intense UV light passes through, the process of solidifying resin is faster and you"ll experience quicker layer curing times in as low as one or two seconds. With a 129 x 80 x 160 mm build volume, you can generate some decently sized prints. It"s on par with the previous-generation Elegoo Mars Pro and Elegoo Mars, but bigger than the Anycubic Photon S or Phrozen Sonic Mini 4K.

The Elegoo Mars 2 Pro doesn"t depart from the overall design of its predecessor. It still rocks an acrylic hood, conveniently-located USB port on the front, single linear rail, and integrated carbon filter. A rubber gasket fits over the bottom of the acrylic hood for a tight seal that helps keep odors in. Most changes are internal though. The higher resolution screen makes for a lower pixel density since it"s stretched across a larger build area. But printing speeds are faster with the monochrome LCD screen.

Print quality is outstanding. This should come as no surprise. Generally, resin 3D printers deliver better print quality than filament printers, and the Mars 2 Pro comes through. What"s more prints generate quickly. The test print of two rooks took just over 2 hours to print. That"s an impressive time, and about two times faster than the Mars Pro. Built quality is great with several touches that improve everyday use. The carbon filter successfully reduces an aroma, though it"s still best to print in a well-ventilated room. A front-facing USB port means no fumbling around for the flash drive on the back of the unit. Disappointingly, the LCD screen is not protected by a tempered glass protector as found on the Mars Pro and original Mars. It"s easier to scratch so you"ll need to be extra careful. 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.

Regardless of specs, the real test of a 3D printer is quality of prints produced. I began by printing the test files on the Mars 2 Pro. Like past releases, Elegoo includes two rooks as its test flies. For all of my test prints, I used Elegoo water-washable resin.

Renowned 3D modeling artist Cobramode offers some sweet 3D printable minis. I printed out Cobramode"s Sadiq Mortuary Guild Conciliator. With supports, the mini printed flawlessly. I was incredibly pleased with the quality of prints as well as speed. It"s a good balance. The rook took a bit less than two and a half hours, about twice as fast as the original Mars and Mars Pro. Cobramode"s Sadiq Mortuary Guild Conciliator took around three and a half hours. Although larger prints take less time on my filament printers such as my Anet ET5 Pro, the Elegoo Mars 2 Pro trounces FDM printers when it comes to quality.

And finally, I printed the ultra-popular Star Wars Deathtrooper. It"s become something of an unofficial test file for resin printers, and the Elegoo Mars in particular. The Deathtrooper printed flawlessly. Taking about five or so hours, the Deathtrooper emerged from the resin tank with exquisite detail. Once again, I was pleased with its balance of speed and print quality. Despite the slightly lower XY resolution when compared with the Elegoo Mars Pro, I didn"t notice any real-world quality impacts when using the Mars 2 Pro.

Like its other resin printers in the Mars, Mars Pro, and Saturn, the Mars 2 Pro uses ChiTuBox as its slicer. If you"ve used any 3D printing software, it should be simple enough to grasp. There"s a slight learning curve that comes with the resin territory. You"ll often have to scale prints down, add supports, and hollow out your prints. Although that"s not unique to the Mars 2 Pro since it"s universal for resin printers across the board, it"s still worth noting. Nevertheless, ChiTuBox is easy enough to use. On my sliced 3D prints, it took only a few minutes to rotate 3D models, add supports, and hit slice.

Once again, Elegoo has wowed me with its attention affordable, high-quality 3D printers. The Elegoo Mars 2 Pro makes several worthwhile improvements over the first-generation Mars Pro. Its monochrome screen allows for quicker printing time, much faster in fact than you"ll find with other resin-based 3D printers. Though screen resolution gets an upgrade on the Mars 2 Pro, pixel density takes a minor hit with a 3 micron downgrade. Though some makers may shudder, I"m more than happy with print quality and particularly with the drastically increased printing speed. My only concern is that the LCD screen isn"t protected by tempered glass, though the LCD screen is user-replaceable. If it gets scratched or damaged, you can repair the Mars 2 Pro yourself, but hopefully it doesn"t come to that.

The real question is: should you buy the Elegoo Mars 2 Pro? If you want a great printer that balances speed and quality, the Mars 2 Pro is a solid choice. For newcomers that don"t already have a resin printer, the Mars 2 Pro is a good buy. Most of the compromises are pretty negligible, though the screen which lacks protection and can"t be replaced is a potential concern. Granted, the monochrome LCD should prove long-lasting and you should probably be cautious around your LCD screen regardless of whether or not it can be swapped out.

But what about the existing owners of a Mars, Mars Pro, or another resin printer? When compared to the non-Pro Mars, the Pro and Pro 2 are absolutely worth the upgrade. Pro owners are probably fine with the Pro and don"t need to switch. But if you"re looking for another unit, the Mars 2 Pro is a stupendous choice. However, there"s a demographic that should consider swapping printers: professional and semi-pro printers. If you sell minis or 3D printed objects and need to set up a print farm, the increased speed of the Mars 2 Pro makes it absolutely worth the upgrade. Ultimately, I"ll likely designate the Mars 2 Pro my go-to for resin 3D printing with the Saturn for larger prints and the Anet ET5 Pro for filament printing. With several improvements to printing speed and quality, the Elegoo Mars 2 Pro is one of the best 3D printers on the market.

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.

Looking for one of the best resin 3D printers? The Elegoo Mars Pro offers cutting-edge MSLA technology, a carbon filter for toxic fumes, and premium build quality for around $300. For its level of detail and quality, it"s one of the best printers for those who want to produce small-format miniatures or models.

Masked Stereolithographic (MSLA) printers differ from regular SLA printers in a simple, but elegant, way: there"s an LCD screen that functions as a masking layer between the resin-hardening ultraviolet (UV) curing lights. The LCD mask controls how light hardens the resin. It even uses anti-aliasing or smoothing of 3D models, in order to deliver streamlined curves that not even the best FDM printers can match. Unfortunately, MSLA printing suffers from the same problems that all resin-based printers have. They smell terrible.

The Elegoo Mars Pro on paper offers the state-of-the-art in resin printing technology in the $300 price range. While its physical dimensions are the smallest of all similar printers in its price range, it still manages to squeeze in the same resolution and build volume as its competitors, with an advertised faster print speed, thanks to its array of 50-watt ultraviolet LED curing lights. Some of its standout features include:

Like most resin printers, the Mars Pro arrives mostly assembled. Users only need to attach a rubber valve around the base of the hood, screw the print bed into the vertical rail, and then load the resin. The bed leveling process isn"t difficult, either.

The most difficult part of making a resin print is using Chitubox. While Chitubox is great, the problem is that the default Mars Pro settings didn"t work. None of the supports held during the early stages of the print process and so the models split apart, with half stuck to the build plate and half stuck to the tank. Fortunately, increasing the support density in Chitubox led to the model"s support not breaking. Unfortunately, I learned that 100% support density leads to solid, unremovable supports. In general, just a 10% increase in supports was enough to keep models from falling apart.

I reached out to Elegoo customer support explaining that my model continued sticking to both the build plate and the resin tank, causing the model to break off at the supports. Elegoo explained that I would need to increase support density rather than increase the lower-layer exposure times.

Cleaning a Mars Pro printer requires straining excess resin using a special funnel/filter to remove hardened plastic. You then need to wipe the tank and tray down and spray them with a 95%+ alcohol solution. If there are any chunks of print clinging to either surface, you must remove them using a scraper. The smell is atrocious and many report suffering headaches when in the same room as a resin printer.

If you"re looking for the best $300 resin 3D printer, the Elegoo Mars Pro, and Creality LD-002R are nearly identical. However, there are a few features that distinguish each from another.

The Mars Pro uses an external power brick compared to the internal power supply on the LD-002R. External bricks allow for a smaller printer and are more modular. If the power supply ever breaks, you can replace it with a standard 72-watt unit. A replacement external power brick also costs less than the internal power supply inside of the LD-002R.

Elegoo claims that the Mars Pro has 50-watt ultraviolet LEDs which should offer 25% faster print speeds. However, in my estimate, the print speed is about equal to Creality"s LD-002R.

The biggest failure of the Elegoo Mars Pro is its lack of an easy-to-access removable panel for its carbon filter. As you can see in our review of the Creality LD-002R (which compares favorably to the Elegoo Mars Pro), the top-deck fan intake includes a removable grill.

On the Mars Pro, I can’t see any easy method of accessing the fan assembly. That means cleaning the fan and replacing the carbon filter may take more effort and disassembly steps. While there are no published guidelines on how often you should replace the carbon filter, a good estimate is somewhere around every six months if you use the printer frequently. HakkoUSA estimates that a carbon filter on a fume hood should be replaced every 640 hours of operation.

The Mars Pro"s exhaust fan is placed at the bottom of the unit, rather than on the side. This allowed Elegoo to use a larger, slower, and quieter fan than Creality.

A minor point of concern is some of the soldering work and a stripped screw. I can see from one of the daughter boards that there are two instances where the solder was not properly flowed. And on the screws connecting the LCD to the chassis, one screw was stripped, which would complicate removal and replacement of the LCD panel.

Despite claiming a year-long warranty on Amazon, Elegoo terms-of-service page specifically states that it doesn"t offer a warranty. Here"s their official warranty policy:

Fortunately, Elegoo offers part replacement. For example, if you experience an issue with your printer and their customer service determines the hardware is faulty, Elegoo will ship you the damaged component. It"s up to users to replace the part, however. Fortunately, 3D printers are easy to disassemble and reassemble.

Having experienced issues with the Mars Pro, I reached out to Elegoo through email, which is their only customer service method. But I sent two emails and received responses within 24-hours. The emails were clear and included generic troubleshooting tips. After applying the troubleshooting tips, I managed to get back to printing within an hour.

It"s also worth mentioning that if you decide to return an Elegoo product, you’re responsible for paying return shipping to China. Unfortunately, on an item as heavy as a 3D printer, the shipping cost is almost as much as the printer itself.

The Elegoo Mars Pro offers 3D resin prints in the 120x68x155mm form factor, without skimping on build or print quality. It"s comparable to Creality"s LD-002R, with better fume sealing and quieter operation. I recommend it to hardcore miniature users, such as wargamers and RPG-players, who want pristine and nearly perfect models.
