ELEGOO Mars UV Photocuring LCD 3D Printer with 3.5'' Smart Touch Color Screen Off-line Print 4.53in(L) x 2.56in(W) x 5.9in(H) Printing Size Black Version

There is a hole happening in all the models.

Excellent print quality.. much better than expected from such a small printer and in this price range.. its like a miracle for beginners and too easy to operate. Chitubox (slicer) is something that i can't miss to mention.. it makes all your work so easy just like a magic wand from some fairy tale.. love this product

Pls say some software to work ..

I ordered the Elegoo Mars around the first of the year. My experience has been positive overall. The support is very good, and I found that using the facebook Elegoo Mars group is very helpful as well. Some pros and cons: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 maintenanceCons:-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.

I could only print half of the test object and it failed. Maybe its user error on my part but t seems like it should be able to pring the test that came with the usb, which took 12 hours, should have been something smaller and faster, I will update when the second attempt is done.Edit#1: After emailing the company I was responded to within 6 hours and sent video instructions on how to set up the print settings coorectly, 4 stars for teh printer and the 5th star for good support~Edit#2: Since reworking the slicer settings this baby has been a total dream, not a single failed print so far Ive printed 4 minis and its been easy going, not layer lines or shifts. Good on you Elegoo for giving us a truly consumer grade product!

I spent about a week reading reviews and comparing to the Anycube. I chose Elegoo because I already buy their Arduino products and use the boards in some really sophisticated microcontroller electronics. I do not need a 3D printer for making figurines but for prototyping and have sent my .stl files off to printers via 3Dprint hubs etc. in the past. This printer puts an end to the expense of having others do my printing. I had been looking at the Formlabs line, and $4000 was just out of touch pricing. My last print by others experienced considerable shrinkage, and when I saw how much money I would spend and how much time I would waste trying to get the prototype right versus $249 for the Elegoo Mars, I finally hit the "buy" button. This will be day 3 of printing, and I am already on iterations 3-7 of my prototype. The resin does come with its expense, but a little goes a long way, and ChituBox also tells you how much your part costs by dividing the cost of the resin by the volume of your part. I can make 1250 small parts out of one liter of Siraya Blu ($50), for example (let's reduce by 20% for waste, and I'd only get 1000). 1000 prototypes would cost me closer to $10,000. By comparison, just prior to buying the Elegoo Mars, I got a quote exceeding $6000.00 just to make the mold for one version of this part. So, this printer completely changes everything for me. I may end up going the injection mold route, but if the tougher resins hold up (lots of data out there) then I may just print them myself. My wall thickness is .5 mm by the way, and I have details that are only .1 mm. These are clearly visible.Now, a word about stinkiness and toxicity. I heard the word "toxic" used in some reviews. Let's put that word aside. The MSDS or SDS sheets are readily available for all of these resins as well as the alcohol you will use for cleaning. I own an inexpensive North respirator with vapor/fume cartridges, and I have been using this mask for 25 years. Had to buy a second one about 10 years ago because I lost the first one. Forget about the paper masks. The vapors you smell are not any worse than you would find working with any epoxy or chemical or bleach for that matter. Once the cover goes over the printer and epoxy bed, the vapors are contained and you don't need the respirator. I am using gloves but then I use gloves for all of the epoxy work I do. Clean up is a little bit of a pain, but so is doing the dinner dishes. Put together a little assembly line. Also, you see people using very large washing tanks. You don't need to go that big. I just used a little plastic container for washing the print in household 91% isopropyl and a UV flashlight I have for curing.I rarely write reviews. This one goes up for others like me, DIY, citizen scientists, who need to make functional prototypes but can only find reviews by people making figurines. I have not had to reach out to Elegoo for tech support, so no comment there. Nothing I have bought from them has not worked, so there has been no need.

. . . I have been sooo happy with this printer. After an initial frustration trying to figure things out and several failed prints, I am getting high-quality, consistent results now almost every time. Their customer support is exceptionally good too with fast replies and a dedicated team. Once you have good settings figured out for whatever particular resin you are using, the results and print quality are amazing. I love it. When you buy it, find the Elegoo Mars owners fb group, a small but good group that has been really helpful for me.

First, the disclaimer: resin printing is not for kids and you need to be safe and responsible. If you want a printer for kids, please understand the difference and get an FDM type printer. The resin is truly some nasty stuff. I am using the Elegoo resin and honestly the smell doesn't bother me at all. it is very mild and not really unpleasant. The resin is, however, a MAJOR skin irritant. You will learn fast. I tried to follow the safety guidelines, however after cleaning the first print and removing my gloves, I think I accidentally brushed just the tiniest spec of this stuff on my knuckle and about 10 minutes later found myself scratching my knuckle. i look down to find that my knuckle was pink and inflamed and extremely itchy. A quick wash with soap and water and a minute later it was like it never happened. Even if you think you didn't get any on you, wash you hands after handling wet resin. do not get uncured resin on you. You will regret it.As for the printer itself, the prints have fantastic detail and I have had no issues with prints not sticking to the bed or failing. Being the obsessive researcher I am when i buy a product like this I read all of the bad reviews on amazon to try to avoid any pitfalls i might encounter and my machine did actually come with one problem. There is a tiny hex set screw that goes in the back of the build plate bracket. its sole purpose is to retain the build plate from falling off when you loosen the leveling screws. Make absolutely certain this screw is in place when you get your printer! When I removed the cover after unboxing, my screw fell out and was lose in the Pinter bed area. If i hadn't caught this, there is a chance the bed would've fallen off when leveling and potentially cracking the lcd screen. The only reason I even knew what the screw was for was thanks to a few bad reviews that I had read so thanks for that! Elegoo - please put a little thread locker on this and save everyone the hassle.One more note: printer does not come with resin. I again knew this from reading other reviews. I chose the clear resin and honestly don't recommend it unless you have a use case for a frosted glass looking part. The clear resin takes 33% longer to print with and if you need to fully cure(harden) it it turns kind of yellowish anyways (see pics). I guess i should have been more thorough researching the resin, but i kind of assumed they all were the same.
