I’ve been LOVING my Saturn 4 Ultra 16k resin printer. I use Sunlu 14k ABS-like resin. My minis come out absolutely amazing and flawless every time. No setting changes or calibration was needed. The printer has taken care of everything itself.

Elegoo Saturn 4 or Anycubic M7? (Ultra, 14K, 16K, Pro and all)

This printer is compared to the Anycubic M7 range, praised for its ergonomics and stable file format, but its 16K screen is deemed largely unnecessary and offers no real benefit over 12K.

Saturn 4 Ultra 16k vs Mars 5 Ultra vs Heygears RS

I have both S4U16k and Heygears RS Turbo. I would say the technology inside HS is much better: real auto build plate leveling, better sensors enable features like peeling force monitoring. Overall it is a much more reliable machine. S4U16K is cheaper but it is by no means simple machine, the tilt vat mechanism and spring loaded plate often cause more trouble that it worth, but it can absolutely print beautifully when you tune it right, it is just long and often frustrating learning experience.

Saturn 4 Ultra 16k LCD Screen Issues

I've been troubleshooting my Saturn 4 Ultra 16k going on a month or so now. I had a great time printing minis and had very few issues until I had a firmware update in April which caused my printer to not recognize the Z motor and the LCD screen. I worked with support to get a different firmware version which did resolve that initial issue, but after running a test print, I found that my LCD was no longer allowing any light through. After going around with support, they said that my LCD was out of warranty and that it should be replaced and appeared to be damaged. ( I had no visible damage on the screen, nor had I had any spills of resin into the printer) Well, I ordered a new screen and installed it this morning. I was sure to check that it functioned , and sure enough I got the Elegoo logo on the LCD both before and after reassembly (all green too, but I lost wifi for some reason). I set up a test print and left it for a bit, but when I checked back in, there was no cured resin on either the FEP or on the build plate. I checked the LCD again, and the new screen is no longer working but this time it shows an error in the LCD connection. I did some more poking around and then reconnected all the cables and reflashed the firmware using both the repair firmware and the version I found on another post from a couple months ago with similar issues, but with no lock. Anyone else seeing similar issues? I've already followed back up with support, but figured I would post in case someone else was going through something similar. TLDR: LCD went out after firmware update, replaced screen worked fine until test print, now it's all black and showing an error after checking and replugging.
