ELEGOOMars 4 Ultra MSLA 3D Printer with 7-Inch 9K Monochrome LCD, Wi-Fi Connectivity, Effortless Leveling System, ACF Release Liner Film, Printing Size of 6.04x3.06x6.5 Inches

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.

Very good printer for the price that I paid. Had some issues with the screen, but customer service was able to help me get the issue resolved. Prints great, even though it is somewhat of a smaller build plate when compared to other build plates. The reason for the 4 stars is that Elegoo had went from a CBT file to a GOO, which will not work the AA function on the different slicers. Other than that one complaint, the printer is great.

I've had many 3D printers but this is my first resin printer and it does well!! Because of the leveling tank, almost all the guess work is taking out. Just wish resin printers didn't smell, but I was able to add a ventilation system to the case it came with!

I bought this after a successful 2 years with my Mars 2 machine, that machine never had a problem until the board burnt out and misplaced some parts during disassembly.This machine I thought would be easy to work with much like it's older generation...it's more streamlined and has easy touch function. However, the profile settings for it don't match the Mars 2 so getting documentation for your resin is difficult and even then, it won't work!Every single print test I've done has come out to being a total failure, and because this machine isn't widely used, finding others with similar setups or even materials such as water washable resin are almost non existent. I had to wait until the cold season was done before I could print, and now I've had the machine to long to send it back, along with the fact that someone in the family threw the box away.Now I'm paying off a $300 paper weight.

Fantastic entry level resin printer and at an unbeatable price. I have now printed through 3, 1000g bottles of resin and have had very minimal failures, most of which were imo design or support flaws that were easy to correct and printed fantastic once corrected. The setup is insanely quick and the program is super easy to use although I use another program for my supports as is my personal preference. I highly recommend to anyone looking to get into resin printing and the only advice would be to get a better thumb drive, I personally have not had issues with mine that weren't quick fix but every once in awhile I have to unplug and replug in the thumb drive to get it to read on both the pc and printer but that has been 2 out of probably 100 uses. I have stress tested this printer to an insane degree and even gone 20 consecutive prints without cleaning or re-leveling with only one single failure in that 20 where the print detached from the print bed and that was the 20th print. Well done Eligoo this printer is tops.
