ELEGOO Mars 5 Ultra Resin 3D Printer, 9K 7" Mono LCD, High-Speed Printing 150mm/h, AI Smart Camera, WiFi-Transfer, Auto-Leveling, Printing Size of 6.04 x 3.06 x 6.49 inch

This is my first Elegoo product and so far I am very pleased with the company. The instructions on set up were easy to follow and my first print (the rook file included with the printer) came out fantastic!I was having issues with printing after that though, and having thought I had ruined the film in the resin reservoir, I purchased more. Once those were in and a new one installed, I went through the process of setting up the machine as though it were fresh out of the box and during the exposure light test, I noticed a MASSIVE spider web crack in the LCD (pictured).I reached out to Elegoo support and they responded the next day! They were very kind and apologetic for the problem and offered to send out a replacement LCD and included a video on how to install it once it arrived. Their support was kind and professional during our emails and were quite prompt giving the time difference. I am very pleased with how the interaction went and look forward to working with this company more as the printer was great (the quality is amazing) and they have such wonderful customer service!

Print quality is good, very small layer capability. Very impressed with how small figures can be printed. Customer service is good, just don't harass them cuz they're not engineers, they didn't design the 3D printer, they help with issues with the printer is/can be having. Problem is with the manual and the screws that come with the 3D printer. In the manual it says to use Chitubox, but Chitubox(pro, beta, basic) (after being updated) won't/can't save projects/prints as .ctb format which is the file format required to make prints on this product. So I downloaded Lychee Splicer which can save files as .ctb files. Also, watch for print remnants that can stay in the resin, that stopped me from printing for 25 minutes and forcably unevened the top printing plate. The screws have a plastic thing on them that after time becomes stripped and very annoying to get off. To fix that, I bought M4/#4 screws that are 40 mm's (1.578 inches) long along with nuts for those screws to act as spacers and replaced the screws that came with the 3D printer. I used a 9/32 socket on a socket wrench to remove/put back the 40 mm screws into/out of the the resin tank. Otherwise everything else is good.So in short, despite the manual saying to download Chitubox, download Lychee Slicer by Mango 3D if you want to be able to save files into usable files/prints. Also, I would recommend buying M4 screws that are 40 mm's long and nuts for those screws (to act as spacers) to replace the inevitably gonna be stripped screws that come with the 3D printer.So in short in short, before buying this product, for maximum succession (without unexpected stuff), it's recommended to download Lychee Slicer by/from Mango 3D and to buy M4 screws that are 40 mm's long as well as nuts for those screws. And to have a socket wrench with an usable 9/32 sockets for those screws.

Update Reviewed in the United States on December 1, 2024After communicating my technical issues to the Elegoo team and presenting my case (you can review my first review below for more details), they finally decided to send me the faulty components, including the LCD screen, after exactly one month of exchanging daily messages and emails at dawn (adjusting to Shenzhen China's working hours). Pleasantly, they even took care of all taxes and transportation costs. When the order arrived, they continued advising me on how to install it, and I am assembling everything to finally use the printer correctly. I will update you when I conduct my first printing tests, as I have not yet tested the adhesion with the laser plate, which is scratched and was not replaced by Elegoo at the moment. From what can be seen so far, it is a very good 9k printer from Elegoo, but what impresses me the most about this company, Elegoo, is their customer service and technical support. They are very efficient and should be recognized by everyone. You can check more reviews and realize that this opinion is very common and not just personal. They really strive to make the customer feel satisfied with their purchase investment and loyal to the brand, even with the variety of Elegoo brand resins they sell. I would give them 5 stars, but because of everything that has happened, 4 stars for now. I will keep you informed.First Reviewed in the United States on October 29, 2024:Absolute Garbage Disappointing and Frustrating Amazon CS Experience with Poor Customer SupportHonest Review: I am a regular Amazon buyer who makes many verified purchases continuously and until I get a full refund I will not change my opinion about the ELEGOO Mars 4 MSLA Resin 3D Printer which turned out to be a huge disappointment and a piece of junk. Lines appear on the 9K monochrome LCD and objects simply do not stick to the build plate no matter the settings or adhesion times on the first few layers I try. I am very disappointed with this 3D printer because it is clearly a manufacturing defect.Despite setting exposure times of 60 seconds, objects refuse to stick to the entire plate (only in parts, check out the video I made). Also the prints always come out crooked, probably also because of a slightly crooked Z-axis as I leveled and calibrated a sheet of paper a thousand times to make it neither too tight nor too loose and it still prints poorly. Not counting the amount of money I have lost on bottles of resin from the same Elegoo brand that I also bought on Amazon and that I chose with the hardest quality like ABS 3.0 trying to MAKE IT WORK AND STICK.To make matters worse, Amazon customer service refuses to cover the full shipping costs to return it and get a refund. They only say that due to policies they cover a measly $150usd, while returning the printer costs me $350usd. All this by sending them and showing them quotes from three different carriers, that is, they insist and they don't care that I spend an extra $200usd but that I return it so that they can refund me $180usd which is what I paid for the printer. What a lack of common sense, who does that? (This is the reason why I have stopped making new orders on Amazon and have canceled those that were in the shopping cart in process, there is no Guarantee).Please do yourself a favor and avoid this printer with its inadequate support from this Elegoo brand and all of their products and consumables. I hope to do an update soon and let you know what is going on with this case and if this Elegoo company has spoken with Amazon to resolve something. I will keep you posted.In the meantime, save your money and look elsewhere for a 3D printer that actually works. Thank you for taking the time to read this extensive honest review and I hope you will follow my advice.
