ELEGOO Mars 3 Pro Resin 3D Printer with 6.66 inch 4K Monochrome LCD Screen Odor Reduction Function Fast Printing and High Accuracy 143mm x 89mm x 175mm Large Printing Size

After a false start with a bad leveling of the build plate, I have been printing out awesome miniatures and even a few dice towers for a friend. As it is my first resin 3d printer I do not have anything to compare it to, but I have not had to relevel the build plate after the first correctly done time and Im a couple dozen miniature in with the only problems I have encountered stemming from my inexperience applying the proper number of supports and even that rarely messing up the miniatures too badly. Great 3d printer, would recommend.

This is my second resin printer and I am so pleased with it. The quality of the prints are outstanding, the adhesion to the platform virtually flawless - I am so very pleased.

Still learning to work the thing properly, theres a bit of a learning curve thats not as easy to overcome passively like filament printers due to the noxious chemicals and safety procedures involved, but thats resin printing. I want to rate it highly, though, because the company was super helpful. One of the supports broke off and fell into the vat, then the build plate pressed it into the screen, breaking it. Elegoo sent me a new screen and it was fairly easy to install, as have been most of the quality of life modifications Ive made to the machine as I learn more about it. Im at a stage now where Im not sure theres any reason to use any filament that isnt transparent, hopefully I at least have a chance of making stuff like that out.

Started out great and worked fine. All of a sudden it started to not print anything. Everything is just gooey and melted. Have no clue what changed or happened. Very frustrating and Im just unhappy with my purchase. Cant tell if its the new order of resin I got from them thats a bad batch or what. I am waiting for a different brand of resin to give it a shot if not its most likely the printer being junk.

i have been into FDM printing for years since the first makerbot and in 2015 patented an enclosure i protoyped on an early form labs printer when i had work. during the pandemic, i got back into resin casting as a way to create enclosures and replicas of various jewelry or games i cant afford. as i was choking on the fumes of a non vacuum aspirated urethane based epoxy one morning i remembered that fdm printing had gotten faster, safer, and cheaper over the past 5 years, so i bought first a brand of 3d printer that was recommended with a mono screen. it arrived and was tiny and worse, printed the sample file and then refused to work again, so despondent i returns it. a few days ago, i was looking around for resin when i noticed this green printer and said huh because i believed only red printers could cure correctly. maybe it was bold but i just ordered it on the spot. it arrived, and heres three things i noticed : Way larger than the other printer id gotten for the same price with a better resolution uv emission panel and far easier resin loading and calibration. this was possible because secondly the instructions are super clear about what to do. i mean, you honestly cant really mess it up, i liked even details about turning the alignment screws in a certain order and to use a4 paper ( i sacrified some of my tomoe river stash for this because i figured if im going to use real a4 paper its best to use the best paper lol). and third, the detail is really great. my first print was the above cleric. i wanted to try chitubox right off as i had not used it with the prior printer that broke. i importrd the file that came in a set of medieval figures on the usb stock with this printer as an stl, built supports, and printer to some tough black resin. thats literally the most basic calibration with chitubox default settings. impressive.my final thought is that the one bad thing i noticed is after this print and another of the same for my spouse, i noticed leakage in the resin at. i cleaned it of course and found two small holes in the plastic lining. i am certain i didnt cause them while cleaning as they are pinprick sized and my best guess is that resin build up after my first print created supports that did not come off right and the initial layer formation crushed them. it has been hard to find online how to replace this plastic. i can find examples for the mars and the mars 2 pro but not this mars 2 - this bothers me because id like to get 2 more resin tanks so that i could store resin in the tank for short times while printing multiples of the same objects in different materials as i djd with our form labs long ago. however, i cannot find the green tanks for sale and the dimensions of metal tanks and red tanks differ slightly. honesty disclosure is that elegoo and i have been on communication regarding this issue and i do plan to share them this review with hope that they can send me a new resin tank and plastic so i can get going again. all in all id say that this printer fits a sweet spot in the maker community for what id call the cloistered creative - if you have basic knowledfe of many fabrication techniques and can run 3d software, this is your bat mobile printer and its a blast.

Great 3d printer, Got this so I could make stuff for grand kids. Quote ( hey grandpa can you make me the Queen Mary, I give it my best shot) 5 years old and always thinking-Love Him. This will be so fun @ 61 years old. They are not only for kids, old folks need toys too. This a GREAT printer! Easy so far, trying Elegoo water resin out seems to work great.

Good for the cost, easy to setup and easy to do the first print

Amazing small-scale resin printer. This was my second printer. The first I had purchased directly from the manufacturer. It was an Anycubic Photon Zero. The thing broke and I could not get them to refund my money. This printer worked out of the box, easy to use, print quality is amazing. Best part, if you buy through Amazon, you will have the protection of Amazon’s return policy. Don’t buy from the manufacturer. These Chinese companies will take forever to reply because their offices are in China. They do not provide any phone numbers and ship replacement parts from China. Meaning that replacement pets will take 2 weeks or more to arrive. Order from Amazon, even if it’s a little more expensive. The protection of having Amazon between you and these companies is worth it.

Arrived this afternoon and it is currently in the process of printing the elegoo sample rook chess piece. So far its making very timely progress. Things that stood out to me. 1. This thing is incredibly well packed, in the best way. Its very easy to pull out all the packing material as they are large foam pads. Its very secure inside the shield as well as around it. absolutely 5 stars for its packaging. 2. Its tiny, again in the best way. Coming from a much more expensive and enormous resin printer I used at work for a while, this thing can print a surprisingly large volume being so small. And it weighs nothing, so it will easily sit on a shelf out of the way if youre in a small room. 3. More a point to the resin but, there is almost no odor whatsoever. Im using the Elegoo ABS-like grey resin and I cant smell a thing. Again, I used to print sleep apnea appliances in a $5000+ machine with $150/bottle resins that were FDA approved etc. and it stank to high heaven. That might also be because I had a few co-workers who were exceptionally uncaring of keeping the printer clean and spilled resin all over it constantly... This thing emits almost no noticeable odor despite not having any ventilation that I can see. 4. The main display is clear and simple to use and the instructions are quite verbose and helpful. So far, everything is looking good. Ill edit this later when I get to printing a few other models of my own. Edit, still completely loving it. It prints with amazing detail. The one thing that I will say though is that there is a bit of a learning curve with using the chitubox software which is the program that allows you to place supports for your model as well as preps it for the printer. Watch lots of videos on support settings and you should be fine, but expect a few misprints in the early stages of printing, especially if youre printing small and complicated models. Edit 2: started having a bit of trouble with the ABS-Like grey bonding to the printing bed on more complicated models. I tried messing with a few settings and discovered that about a 7mm base lift and regular lift distance is better than 5. Shortly after that I switched to their water-washable blue and I am incredibly impressed with it. Better details for sure. I used 30s base cure and 2.7s regular layer cure with the same 7mm lift distances and everything has turned out beautifully. Its also much stronger than I had originally imagined. Youre not going to want to throw your models against the floor very hard, or even drop the more intricate ones, but thats not too difficult to monitor anyway.

Let make a record strait, it DOES NOT go 4 time faster, its more like twice as fast at the most... Wow that is nice. The speed is improve, the exposure time is less but every other thing the same. Than half of it goes 4 time faster, that would be a thru statement... It is faster, it does have a better volume and the same or better result (resolution wise). I taught it would need a better or different resin but my test show no issue with the resine I was using on the Mars original. its so much better and for a bit over $200... If your time is not free like me, get-it. I retire my Mars1 and got a Mars Pro 2... Notice the $100 more doesnt give much more than a better cover color and maybe better printing surface. And one more plus for it, the Vat from the Mars original fit and so is the print surface. The print surface of this machine and the pro version are a little bigger but work from one to the other (with the need to be zero), its a nice plus. It is to notice the vat is made of clear, green tinted material, the Pro and the original are Aluminum. I cant say, if its not as good. Its solid, looks good and give excellent result. As usually, I customize-it; I add a magnetic print surface and add heat. I keep all my resin printer at 40c and have like 100% print success. As you know the magnetic surface is to ease the part separation. It is to notice the printing surface is improve from the Mars1 to the 2 and again to the 2Pro. The one being painted (and peal with the time) the 2 is like machined and the 2Pro sandblast what minimize the reflection and add adhesion (So they say). I go with the Magnetic peelable spring steel, that I cant tell if one is better than the other. The first generation (painted surface) did leave paint on some parts, what is less than desirable, if you dont use skid and print on the table and use the piece unpainted. Instruction and software. The instruction is Ok but at least theres some, right! The UI is different from the first gen the 2 and the 2 pro, specially in the zeroing and setup. It just different icon and little variation on how to do-it but still intuitive, youll figure-it out. The slicing is the same, you just have to pick the right printer that goes to. I keep the original set-up on all the printer and have like zero issue. I may be able to save few seconds here and there but I go for the easy print, no headache. And as the slicer goes, I find it simple and versatile. I dont see much to improve there. If you have the Mars original, this guy is a must-have, if your time is valuable. Its allot more for the buck. Personally I dont like the Green but doesnt affect the safety or performance. Its like an eye-sure in the printer line-up (Ya I got 4 and one Saturn, the big red guy) Ya! Why dont you go create something, its better than reading me ;-) Keep having fun
