About this item
- 【Fast Printing and less maintenance】Mars 2 comes with a 6.08 inch monochrome LCD of 2K HD resolution and only takes 2 seconds per layer exposure to cure resin, which could significantly enhance your printing efficiency. Mono LCD has a much longer lifespan and stable performance during long term printing, thus saves your cost.
- 【Outstanding prints and ultra accuracy】Brand new light source structure provides more even UV light emission and working together with 2K mono LCD, the printing details and precision are greatly improved and the 3D printed models are fascinating.
- 【Sturdy build quality】CNC machined aluminum body makes Mars 2 a very formidable machine. Newly-designed build plate has a much stronger adherence during printing and enables consistent printing success.
- Multi language interface】Mars 2 now supports 12 kinds of languages so customers across the world could operate the 3D printer more conveniently without barriers. The newly added 10 languages are Japanese, Dutch, Korean, French, German, Russian, Italian, Spanish, Turkish and Portuguese.
- 【Warranty and Service】We provide a 1-year warranty on the whole printer and 6-month warranty for the 2K LCD (FEP film is excluded). And we provide 24 hours customer service.

There was a problem filtering reviews right now. Please try again later.
I will first start by saying that I was hesitant to buy a resin printer because of the "mess", smell and other down sides I had previously heard about. I did my research to find the best fit for my needs and budget. The Elegoo Mars IS THE BEST! I'm blown away by the print detail and how easy it is to use. There's a slight learning curve and several things I don't like about resin printing compared to FDM printing but it's still worth the extra work and slight mess. I have several CR-10's and I will still use those for large prints but for small detailed prints, this is the machine to use!
First, the smell isn't nearly as bad as people said it was. It's probably best to have it in a shop or garage and not in your house because it does give off a slight resin odor especially the first time you use it but it's not that bad at all. I work around it all evening and it is never overwhelming or nauseating. After about 5 minutes in my shop I don't even notice it anymore. It does not smell any more than my FDM printers.
Second, it isn't that messy as I previously read in other reviews. You need a silicone nonstick mat to put down to avoid drips and spills but it's well worth the 20 bucks to get one.
Third, Did I mention yet the print detail is AMAZING! Most FDM printers print at a minimum of .1 and the Mars prints at a .05 layer height which means NO PRINT LINES to clean up!
Last, you do need to buy a UV light to cure your parts. I did a quick test and left several parts away from the sun to see how long the full cure time would be and they are still tacky to the touch after 3 days. Unfortunately we have had cloudy days since I bought the printer and I can't rely on the sun to cure my parts right now.
THE DOWNSIDES: These aren't a deal breaker for me but the print bed size is small but I knew that going in. That being said, it's still a good value for the bed size. If I wanted a bigger bed I'd have to go to a 1,700 dollar machine. It is a little more of a mess than an FDM printer. You do have to pour resin in a basin, wipe up the drip from the bottle that seems to happen every time and wipe off the bottle every time you fill the tray. I have only cleaned the tray once in the 3 days of constant printing because I had a mis-print that caused the resin to cure to the bottom of the resin tray. It was my design error and no fault of the printer. I scratched up the film on the bottom of the tray so I'm sure I'll have to replace that after numerous prints but I was expecting that anyway from previous research. The film typically is under 20 dollars to replace and you get several replacement pieces and the labor to do it seems pretty easy.
Cleaning the resin tank is simple and straight forward. 99% alcohol works great and you have to use alcohol to rinse off your printed parts but here's how I look at it.. I sometimes spend hours sanding prints off my CR-10 (that I love) and now I'm spending minutes cleaning up small resin drips and occasionally cleaning parts. It's a good trade off on time.
I HIGHLY recommend this printer and do plan to buy an even bigger one eventually. This thing is amazing! I'm very pleased with Elegoo.

I HIGHLY recommend this printer and do plan to buy an even bigger one eventually. This thing is amazing! I'm very pleased with Elegoo.
Pros:
-Very easy to set-up and use (software is relatively simple to use). Far fewer settings to adjust vs FDM printers (only 5 or 6 settings really make a difference in the end product)
-Less finicky than FDM printers (not as susceptible to print fails from factors like first layer adhesion/settings). It's very forgiving.
-Incredible detail and resolution
-Good support
-Resin is ideal for painting
-Relatively low maintenance
Cons:
-A bit messy
-A bit smelly (not as bad as people mention IMO).
-A bit slow. Not a true con, because DLP laser resin printers are expensive, commercial grade printers for higher volume application.
-Elegoo resin sticks to everything and transfers easily. 99% isopropyl/ethyl are the only readily available solvents to remove resin from surfaces. (Tip: after printing, rinse with 99% isopropyl or ethyl alcohol, then water, then alcohol and water again.)
-Quality control: I had to return first 2 units. First one had an issue where the rising and lowering metal plate would not detach from FEP during first several layers. SOLUTION: add a piece of painters tape to corner of LCD screen, under FEP film, but do not cover active pixel area! (Issue is a vacuum is created that cannot detach).....Second printer had to be returned because units are susceptible to a part knocking loose during shipment, which will cause the UV lamp to turn off randomly. I found tapping the side of the unit helps temporarily, but it is shorting out. Support has a solution to fix it yourself. Just wrap it in an insulator that doesn't conduct electricity (I deferred to the amazon exchange process).
Some tips:
The printer has a relatively easy learning curve. Default settings in Chitubox 1.3 are ok, but not ideal. For Elegoo transparent resin, I use a minimum of 8 seconds per layer at 0.05mm height. For opaque resins, I use 11-12 seconds per layer at 0.05mm. As a default, I use 8 bottom layers at 30 seconds each. I don't change settings for different layer heights. For most models, especially ones with large internal volume, be sure to add a drain hole in the software or manually with a drill bit after printing. If you drill too small a hole, another hole to let air may be necessary.
-Always check the resin reservoir after printing and especially after fails for resin that is stuck to the TPE film and loose in the leftover resin. They include filters for this.
-When picking models and preparing a print, you should use any empty area of the print bed for additional models. The only thing affecting print speed is the height of your models. You can print as many models simultaneously as you can fit on the bed without affecting print speed as long as you don't add a taller model. (This is not the case with FDM printers).
-Get a nail curing lamp or put your models in the sun to cure for 30 min-1 hour for increased strength. Too long will change the color of some resins (like elegoo transparent).
-Try the transparent resin at least once. Transparent resin prints the fastest and you can also calibrate and level your bed without having to empty the resin and clean it (you can see through to the LCD screen to align the ballast without removing the resin).
--Another reason, is that transparent resin allows you to see the internal structure of your model. You can see the infill grid and see if any resin is trapped. I didn't understand the importance of a drain hole in some models until I used transparent resin and saw liquid resin moving freely in a finished model.
Despite needing to make an exchange, my overall experience has been very positive. For $500, I think it is a great deal relative to other resin printers with similar abilities and performance. I would definitely make the purchase again.

-Elegoo resin sticks to everything and transfers easily. 99% isopropyl/ethyl are the only readily available solvents to remove resin from surfaces. (Tip: after printing, rinse with 99% isopropyl or ethyl alcohol, then water, then alcohol and water again.)
-Quality control: I had to return first 2 units. First one had an issue where the rising and lowering metal plate would not detach from FEP during first several layers. SOLUTION: add a piece of painters tape to corner of LCD screen, under FEP film, but do not cover active pixel area! (Issue is a vacuum is created that cannot detach).....Second printer had to be returned because units are susceptible to a part knocking loose during shipment, which will cause the UV lamp to turn off randomly. I found tapping the side of the unit helps temporarily, but it is shorting out. Support has a solution to fix it yourself. Just wrap it in an insulator that doesn't conduct electricity (I deferred to the amazon exchange process).
Some tips:
The printer has a relatively easy learning curve. Default settings in Chitubox 1.3 are ok, but not ideal. For Elegoo transparent resin, I use a minimum of 8 seconds per layer at 0.05mm height. For opaque resins, I use 11-12 seconds per layer at 0.05mm. As a default, I use 8 bottom layers at 30 seconds each. I don't change settings for different layer heights. For most models, especially ones with large internal volume, be sure to add a drain hole in the software or manually with a drill bit after printing. If you drill too small a hole, another hole to let air may be necessary.
-Always check the resin reservoir after printing and especially after fails for resin that is stuck to the TPE film and loose in the leftover resin. They include filters for this.
-When picking models and preparing a print, you should use any empty area of the print bed for additional models. The only thing affecting print speed is the height of your models. You can print as many models simultaneously as you can fit on the bed without affecting print speed as long as you don't add a taller model. (This is not the case with FDM printers).
-Get a nail curing lamp or put your models in the sun to cure for 30 min-1 hour for increased strength. Too long will change the color of some resins (like elegoo transparent).
-Try the transparent resin at least once. Transparent resin prints the fastest and you can also calibrate and level your bed without having to empty the resin and clean it (you can see through to the LCD screen to align the ballast without removing the resin).
--Another reason, is that transparent resin allows you to see the internal structure of your model. You can see the infill grid and see if any resin is trapped. I didn't understand the importance of a drain hole in some models until I used transparent resin and saw liquid resin moving freely in a finished model.
Despite needing to make an exchange, my overall experience has been very positive. For $500, I think it is a great deal relative to other resin printers with similar abilities and performance. I would definitely make the purchase again.
