  • I like it, but....
Size: Mars 3 4K
Update - 8/29/23 - I ended up not having a chance to really troubleshoot my issues with the printer after getting it. I got frustrated with the failure of the FEP, then our family moved and it was packed away for nearly a year, and I just didn't have time to mess around with it to get it figured out. I was just about to give up and give it to someone who had more time to getting it working, but decided to try one last time to get it to work. I'm glad I did! It turns out that the resin I had started using initially was a resin that, while it sort of worked in this printer, it was made for a specific brand of printer that operated a little bit differently than the Mars 3. The information on the resin was lacking, and I hadn't realized it, and it caused the resin that was partially cured to overheat while printing, which is what caused the FEP failure. Once I realized it might have been the resin, I switched back to some Sunlu resin I had still, and not only did it succeed with a print, I've had about 15 successful prints since, with the only failure being a pre-supported model that had an issue with the base (so it was the stl file and not the printer that caused the issue). With the speed and quality of the prints I've gotten since I was able to figure out my issue, I've bumped this back up to a 5 star! I am not new to 3D printing. Previous to the Mars 3, I had an Anycubic Photon Mono and an Ender 5 Pro FDM. Love the Ender, and really liked the Photon - EXCEPT the maintenance nightmare that it was. It seemed that after every third print, the FEP would get holes, or the build plate wouldn't be level and cause a failure, or the LCD would go out. The last straw was the current LCD was starting to go (just replaced it 2 months before it developed a bad spot) and the FEP leaked and damaged the rest of the screen. Suffice it to say, I was NOT pleased with how often I was having to replace the FEP film, nor the fact that I was going to be on my third LCD in less than a year of printing. That brings me to the Mars 3! I did a lot of research for printers in the Mars 3 price range, and decided that the Mars 3 sounded attractive enough to fit my needs and sounded like it was a little more friendly in terms of maintenance. One of the first things that made me want to get it is that it comes with a factory installed film on the LCD, and it ended up being something that I would need rather early on. This is where the -1 star comes in, within 7 attempted prints (2 failures due to using new resin I didn't know the settings on), one of the prints had a piece that stuck to the FEP. Usually, that's not a huge issue, but for some reason, the print as it kept going developed a sharp point and ruptured the FEP. Of course, this means that resin leaked onto the screen during printing and cured. The film on the screen worked! I just had to basically peel off the protector and carefully get the resin off the screen. Far easier than what I had to do with the Mono out of the box, and that film saved me from having to get a new screen... AGAIN. But, unfortunately, there are no direct replacements for the screen film that Elegoo produces, which is where that one star comes in. It's FANTASTIC that the screen was protected in this case, but it also sucks that there isn't a way to get a factory authorized screen protector to replace it once the inevitable happens. Good thing is I know about screen protector films now, and that I would eventually need one, so I already have one that I bought just in case this happens (Mach5ive). I haven't had a chance to install it and get back to printing, but once I get the new FEP installed as well as that I should be good to go again. Pros: LCD screen protector out of the box 4k resolution - I printed some TINY things with one of the first prints, one being a pirate girl that has a tiny pirate teddy bear on her back, and the details it brought out blow the Mono away. Looks nice Factory screen protector for the push button screen - this is a weird Pro, I will admit, but I didn't take the film off of the touch screen for the buttons. I can still push the buttons through it, and this will keep the screen from getting mucky if there's ever a drip of resin that gets on it! I love that the screws for the vat come out, instead of being embedded in the base of the printer like the Anycubic. Means it will be easier to clean them if/when they get resin on them Metal area around the LCD - will make clean up easy if some spills, even if it cures, can just be scraped off and cleaned. Cons: Plastic base - I don't know how I managed it, but a few drips of resin went down one of the sides of the printer already and cured there before I even noticed it. With having a plastic base, this will never come off. FEP - I know this is one of the things that come with printing with resin, but having an FEP fail after less than 10 prints is disappointing. I know people who say they've been using the same FEP for a year, and I can't for the life of me understand how that's possible Overall, though, I am extremely please with this purchase. Out of the box, it was FAR easier to get things set up and going than the Mono, with only needing 2 test prints to get the settings for the resin I was using tuned in. The detail on small items is amazing as well. Print times are pretty much the same as the Mono, for the most part, so there's no speed improvement from 2k to 4k (not that I was expecting any). ... show more

  • 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
