  • Dicemaker's Perspective.
I bought this printer back in August and wanted to really run it through its paces to make sure that I was happy with it before writing a review. I'm not someone who prints miniatures, I'm someone who makes 3D printed dice masters. I'm still learning, so please take my review with a grain of salt. I typically use a fast brand of resin, since my prints need to be extremely precise. This printer is honestly, largely stress-free. I'm graduating from a Mars 2 Pro, which served me well, but was beginning to show its age. The good: - No adjustment screws for the print head / bed. None. It's a latch that clips into a metal arm, and it's very solid. I don't know why we didn't do this earlier - no more messing around with hex wrenches. If you're someone who liked that, you will not like this. Personally, my RSI-ridden hands are grateful. - Build quality is excellent, anything that matters is made of metal. The outer shell is plastic, which is fine. - Slightly larger touch-screen that works well with gloves on. - Temperature gauge! Nice! (My office runs cold, so this is good to know for me.) It is in Celcius though, so those of you used to using Freedom Units may struggle. - Wifi - actually kinda great? No juggling USB keys either, you can send prints from the slicer. Nice! - ChituBoxPro, surprisingly, is okay to work with! It has some quirks, and I always run my prints through UVTools to make sure they're solid before I print. - Record your prints, see where they fail (this is particularly helpful to me, so I can go back and review exactly when and why a print might not have gone well.) - Resin vat is held on with two long screws that go all the way through the frame of the resin vat and down into the body of the printer. - Tilty vat, supposedly nicer on the FEP? - Came with a resin catch to put on the printer while you unload prints. Very nice. Surprisingly useful, and your printer doesn't get covered in resin drips. - Textured bed. :) This isn't necessary, but it's a nice upgrade over the Mars 2 Pro's smooth bed. - You probably won't need a magnetic build plate. It's a nice to have, but I haven't had issues with the bed. The Neutral: - The hood / lid is not hinged like the Jupiter, which would have been nice, but I guess it's saving a bit of space, so that's okay. - Chitubox sometimes drops information from models and the supports aren't always where you think they are. It's workable, I just wish it were friendlier to other slicers. - The vat has a billion screws on the bottom, just like the Mars 2 does. I haven't had to replace the FEP yet, but I'm dreading that a little. - Replacement parts, including the screen and FEP are a bit on the price-y end. I don't mind, the rest of the printer is hassle-free, so it's a compromise I'm willing to make. - Not sure about the fast vs normal printing speed. I use normal, because I need my models to be perfect. The not so great: - If you're looking for a printer where you can adjust every single setting to an obsessive degree, this may not be your printer. Chitubox Pro allows for a decent amount of customization in how your settings go, but you will have to hunt and peck through the settings to find them because they're not readily apparent. - Doesn't want to talk to other slicers easily. YMMV, I'm still new at all of this. - Camera is uh, below the vat. So... if you're like me and you print models that are no larger than about 2 inches high, you won't really be able to see most of it. I think you can extend the camera upwards but then you're looking at the top of the build plate, so ...? - ChituBoxPro only takes encrypted CTB files, which you can work around using UVTools, but keep in mind if you're an open source advocate that this file format is ... mmm. Sub-optimal. Important stuff: - Remember to take the lens cap off on the camera. My silly self did not, and was confused as to why there were no pictures on my camera. Oops. -You will need to use the BETA version of ChituBoxPro, not the regular one. The regular one doesn't include the Mars 5 Ultra yet. I imagine it will within the year. - If your prints are failing, check your resin settings and check to make sure your environment isn't too cold. I had bed-adhesion issues below about 15C. My office gets super cold, so I had to close some vents to get comfortably into the range that my resin preferred. VERDICT: If you're someone who's making dice masters - which is all I can speak to - this is a great printer for the price and it's treated me very well. Any time I've had issues with my prints, it's because my model was actually broken, or I didn't support the model well enough, so basically user error, not printer issue. SCORE: 4.5/5 - Great printer, somewhat unfriendly to anything outside of the CHITU ecosystem, great for beginners with its simple setup and assembly. ... show more

  • I like it, but....
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
