  • Very Impressed. This little printer is superior bang for the buck.
I have owned several 3D printers including one FDM and 3 different brands of SLA. I currently own an SLA printer that cost 10x as much as this little one. After using this Elegoo, I can't justify spending over $3.5k again because this one is great. The footprint is small. The operating noise is quite quiet. The print speed is impressive. The print quality is as good as my $3.5K. I bought the Elegoo 405nm standard black resin at same time, and that is what I've been using for the sake of this review. Setup of the printer was super easy. Instructions were not confusing. Just level the build plate, set Z zero, quick test of light source, then all done. First print didn't stick to the build plate and so I performed another level and Z zero which resolved the problem. Since then have done at least a dozen prints at the highest Z resolution settings and am very, very happy. Prints are clean with crisp edges. No artifacts and cornflakes flags hanging off the prints. The resin could play a role in these great results but since I'm using Elegoo resin in an Elegoo printer, there's no guesswork or tweaking settings to figure out optimal parameters for a resin. The software was the only aspect that had some disappointments. I did find the software to be easy to use particularly in my cases since I've experience with numerous slicing software. The software version provided on the included thumbdrive is not current though and upon launch, the software tells you that a more current version exists. In order to DL the most current, you have to create an account with Elegoo. I did that and upgraded to V 1.7 which was the advertised retail release. There is another more current V 1.8 but that is advertised as beta so beware. I successfully ran several prints on V 1.7 then I upgraded to V 1.8 to see what was different. That was a mistake. V 1.8 is NOT ready for prime time and did not seem to have proper settings for this model of printer. It did appear to have more enhanced features than 1.7 so I look forward to it being debugged and generally released in due time. One nuisance about 1.7 software is that any command that requires a pop up window, such as saving a file or similar does not pop up the active window in front of the software. In other words, the file save window is hidden behind the open software so you don't know if the software responded upon the command to save. I thought the software was hung up when I first encountered this behavior. The software wouldn't minimize the window either. So I did a Ctrl-Alt-Del to bring up task manager but then when I closed task manager after seeing everything looked ok, then the file save window was brought to the foreground. This is repeatable and so it appears that it is a bug of the 1.7 software. What I do to avoid this is to not run the software in maximize (full screen). When I open the software, I just reduce it with 'minimize' then 'restore down' so that it doesn't occupy the entire screen. In this arrangement, there is not the problem of active window hiding behind the software. If I happen to forgotten to do this and encounter the bug again, simply toggling into and out of task manager seems to free the hangup and then display all the correct active windows. Another problem I had was that the provided thumb drive containing all the software and test model files on survived only one use. After I installed the software from it, I then attempted to copy all of the other files onto my PC to back them up but the thumbdrive failed and then couldn't be read at all. Couldn't even format it after that. Completely dead. ... show more

  • An amazing resin printer!!!!!!!!!
Size: Mars 4 Max 6K
I love this printer. I’ve been 3D printing for the last 6 years and worked with the Creality CR-10, the Ender 3 and 5. I shied away from resin printers from different people saying they didn’t like it. Well I did my own research and decided to try it. Pros: The detail of the models are incredible. The quality of the resin print are strong. Removing the supports is easy to do and doesn’t require a lot of sanding after they are removed. The build plate size is perfect for what I use it for. I love how easy it is to level the actual build plate. The assembly for the printer was easy and simple, right out the box. Being able to print strong clear resin print is a game changer for me. The time it take to print a file on the printer is 10x faster which helps getting my customers taken care of. Cons: The clean up was not what I expected. I got the resin everywhere the first time I pulled a print off. It’s a learning curve going to this from pulling a PLA or an ABS print off my Ender 3. Since then I got a smooth method on removing the prints and getting them in the IPA bath. Changing the FEP plastic on the resin tank is a pain and takes a lot of time if you puncture it. And the smell is a lot but I now have it near a window and able to invest in nice air purifier. I also use a respirator mask and gloves when handling this prints. Make sure this is in a place where you don’t want any table top or furniture messed up and is ventilated. The price of filament vs resin is a little more. I can get more out of a PLA roll than 1KG of gray resin. This printer definitely gets the job done. Once you get passed the clean up and smell it’s a fantastic printer. All and all I love this printer and will use it in conjunction with my Ender 3. ... show more

  • A bit of a rocky road, but worth it. Incredibly detailed and precise prints result!
When the Mars 2 Pro works, it boy does it ever do a great job! Expect failed prints, but when it works, the prints are amazing! There is a learning curve. You have to learn to follow their (sometimes shaky) instructions precisely. If you do, look at my picture. This what the printer can do, and it is amazing! Follow the instructions. Yes, they read like a Japanese stereo manual. They are a Japanese company, after all. They do have a library of videos to help you with problems. Part of the learning curve. Clean up after every print. Buy a few gallons of anhydrous alcohol (99% or better, available on Amazon, of course) for cleanup. REUSE YOUR ALCOHOL! Put it in a clear jar and leave it in the sun a day or two, or buy a curing chamber and do it the convenient (and slow) way. The printer died after 2 months. I had a rocky start with Support. The LCD died. When I replaced it (following their video exactly) after a few tries the new LCD works perfectly. There were other problems. Support tonight informed me they are shipping a replacement printer. I was using the printer to print fabulous items like pictures for my family. With the new printer I can finish printing them. Look at the three eggs in the picture. I printed 6 eggs on one build plate and the vehicles that fit into the eggs on another build plate. Three are pictured. They are TINY. The wheels turn. The ladder and backhoe arm are articulated, and they work! And every one fits precisely into their egg with literally no room to spare. That is just amazing. The tiny elf village, villainously painted by me, is intricate and superbly detailed. The Go Away Gnome, printed 2 to a build plate, will be great gag gifts for family and friends. The deer, poorly lit, are for my hunting friends, a guaranteed hit. The quality of the prints is obvious. The painting, well... Never tried it before. It shows. I found a few million printable objects on Thingiverse, my salvation since I don't know how to create things. I downloaded several hundred for christmas including everything in the picture. Load the STL file into Chitubox, load up the build plate with as many things as possible, then slice and save it and you're almost guaranteed a great print - most of the time. There is the aforementioned learning curve. Sometimes everything but a couple items print. I have not figured out why some items don't materialize. The Harry Potter chess set had 15 pieces on one build plate. 13 printed. Go figure. The machine is built like a Sherman Tank. Heavy. Solid. Getting inside to replace the LCD was a bit of a pain. However, if you precisely follow their instructions and pause the video at every step, it is still a pain, but it is very doable. Just be patient. REALLY patient! The Achilles' heel is the FTP, in my humble opinion. The ones that come installed on the tanks work great. They have play in them. So far I've wasted 7 FEP sheets trying to reproduce their results. HEY ELEGOO! SELL US YOUR FOAM PAD!!! PLEASE!!! THAT is the Achilles' heel. I have found it impossible to get the FEP right using their video and my approximations of the pad they use to make sure the FEP has play in it. Here's how this thing works: The build plate descends to a tiny fraction of an inch above the FEP, which lays flat on the LCD. A thin thin layer of resin remains between the build plate and the FEP. The UV light turns on for a programmed length of time. Then the build plate rises. IF YOUR FEP IS RIGHT, the printed layer is peeled up from the REP from the outside edge to the center of the print. If it ain't right, the sucker sticks TIGHT to the FEP, pulls off of the build plate instead, and you print a slug of resin in the rough outline of what you thought you were printing! Moral of the story? FEP RULES. Good FEP = Excellent prints. BAD FEP and you are sunk. I have so far bought two sets of two spare tanks so I at least have something that works. I truly hope they will sell their sponge pad because I can't afford to keep paying 25 bucks apiece for new tanks just to get working FEP. Argh squared and cubed! Here are the Pros: The Mars 2 Pro -CAN- product absolutely stunning 3D prints. It is a pretty machine. Really. It is SOLIDLY built. They provide everything you need with the printer (except the resin). Their resin works well. And the Cons: The printer is a bit tempermental. The documentation is written by the same guys that write Japanese stereo manuals. Prints -will- fail. There is as much art as there is practice in producing prints. Setup is a real pain. Full setup is required for EVERY print., a huge pain, but NECESSARY. Fill those build plates! Save LCD cycles! Cleanup is another real pain. Wear gloves. The resin is toxic. Clean up WELL. It matters. You have to do the full cleanup after every print. Elegoo Tech Support is super sparing on words. English isn't their language. Be patient. And the resin... Unlike FDM filament, the color pickings are slim. They ain't many, period. I have bought an acrylic dye kit. I will be experimenting with dyeing the white resin. One thing is for sure, you print in one color. Only. On that issue, FDM has resin printers beat, but the quality of the produced models is SO MUCH BETTER THAN FDM'S BEST that there just is no contest. The short of it? GREAT 3D prints ARE possible, even for neophytes like me. The devil is in the details. FOLLOW THE INSTRUCTIONS PRECISELY. Every time. I am very impressed with the performance and quality of this printer, and even more impressed with the gifts I made. I know they will be appreciated! And don't forget Thingiverse. What a wonderful FREE source for printable objects! Try it out. You will amaze your friends and family. Even more if you can paint worth a durn! ... show more
