Entry level 3D Printing

Saturn 4 Ultra (commonly S4U) in 12k or 16k is going to be the easiest printer to get started and successful prints from for a new user. The Mars 5 Ultra is the smaller version with all the same features as the 12k, just different resolution and build volume. The tilt release system eliminates 12-16

Mars 5 Ultra

I did this exact upgrade and, almost a year on, it's more hit than miss. My Mars 3 Pro was a beast and super reliable. Mars 5 Ultra requires a bit more thought and tinkering when it comes to supports and STL placement. The tilt vat does speed things up, but it creates different pull forces in the va

Best choice for tiny figures?

Mars 5 Ultra. All Elegoo tilting vat printers (latest Ultras) vastly simplify the learning curve for exposure settings because a lot of esoteric settings (like lift speeds) just no longer apply. They have a reduced peeling force compared to traditional resin printers, which somewhat reduces the need

Anything i should know before buying the Mars 5 Ultra?

Dealing/Preventing Resin Leaks on the Mars 5 Ultra/Saturn 4 Ultra due to Tilting Mechanism

The M5U includes a factory screen protector, which is under the black tape. It would take some work to get resin past the tape and past the screen protector. The screen protector is mildly pointless, because you can't purchase one separately, and if you purchase the whole LCD from Elegoo or Chitubox

Options for a larger printer

Okay, that looks to be a sample defect on the flatness of the build plate. Spare build plates can be purchased from Elegoo directly. Not all S4U owners have the experience of that reviewer. If I bought an S4U (and I'm seriously considering adding one to augment my M5U) and I got an unflat build plat

Need help deciding on a printer

I have two build plates for my Saturn, the one that came with the printer and the one I purchased to have a spare. The original had poor flatness with a dished center, so that when any three of the four corners touched down, the center remained above the film. The spare arrived practically flat. I h
