Review: Excellent product with fantastic customer service - I spent a lot of time researching 3D printers a few years ago and settled on the Elegoo Mars 2 and have not been disappointed. it has performed flawlessly. I design and produce products for the scuba industry and are available in 90% of the dive shops, Aquariums, Water, resorts and Theme Parks, in the US and World Wide. Occasionally I have to produce a limited run of a design or a prototype and the Mars 2 has been perfect. I decided I needed a bit more capacity with a slightly larger build plate and the Mars 3 seemed perfect for the task. Most of my manufacturing is sub contracted here in the US but the 3D printing is my personal project and is based in AZ. The printer arrived exceptionally well packed but there was a minor flaw in the touch screen. I stated using the printer and was not disappointed. From the very first print to this day, I have not experienced a single fail! For me a fail is lost time and money and I am often on a deadline with these small runs. The small flaw in the screen became bothersome and at the angle the printers are installed it became a problem for me, so I ordered a replacement and exactly the same problem.. I discovered it was an issue with the way they were packing the printer at the factory. The packaging applied pressure to the touch screen and it eventually created a bubble and moire pattern on the screen. Not a problem at some viewing angles but it was an issue for my setup. For me, the measure of a company is not based solely on the quality of their manufacturing nor their QC but the ability to respond to a customer service issues and resolve it effectively and in a timely manner. In this respect, Elegoo is EXCEPTIONAL! Rather than return the product, they immediately sent me a replacement screen, which is easily installed, and followed up to make sure all was OK. I have been absolutely impressed with Elegoo’s response and follow up, and they now have a customer for life. I also purchase their resins exclusively and I ascribe the combination of World Class resins in a World Class printer for the excellent results I consistently achieve with their products. When I need to print, I select the file and push print and I know that in a few hours those items will be ready to ship. I use Elegoo ABS Like exclusively in the Mars 3 and Elegoo Water Washable in the Mars 2 for prototyping. One final point, I installed a flex build plate prior to firing up the printer for the first time. I use both magnetic sheets (current sheets are 1/3 thinner than the one on my Mars 2 purchased a few years ago) one on top of the other for maximum adhesion, and have never had to touch the plate with a scraper. They remain pristine and produce a factory finish when a model is directly on the build plate. In summary, I give the Mars 3 a 5 star rating and Elgoo a 5 star +++. If you are looking for your first 3D printer or additional printers for commercial applications, look no further than Elegoo!
Review: 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.
