Saturn 4 Ultra 16k - keep or wait for Saturn 5?
No, these are not graphics cards. There's a limit to their technological advancement. 16k print is close to injection moulding, any higher resolution is approaching gimmick status. Unless they revamp the tilt vat and improve fail detection, I can't see what tech improvements are to be made. I'm here

Suddenly getting these "flakes" in my prints, could use help.
I was going to ask if it was a Saturn 4 Ultra with the crazy thick raft you've got going on in the first picture. When you let it print rafts that far over thickness (what is that 1.7-2.1mm for a 1mm raft?). Your LCD has pressure spot failures, and it is likely because the build plate and overly thi

WARNING: Saturn 4 Ultra LCD dead prematurely. Elegoo admits "pressure damage" but denies warranty citing "3-month rule" on a known design flaw.
I've written up a longish examination of this issue -- your rest time is too low at the start of the print: https://www.reddit.com/r/ElegooSaturn/comments/1jwcwg2/fixing_saturn_4_ultra_elephant_foot_and/ The easiest improvement to LCD wear going forward is to substantially increase the Rest After Retract

Suggestions for next printer?
If the Saturn 3 (non-Ultra) is available to you, it's the best bang for your buck and last of the non auto-leveling printers worth buying. Usually less than $270. Heygears is running a sale on the Reflex RS for $499, which is the lowest that printer has ever been. It's probably the only auto-levelin

Saturn 4 Ultra 16K Owners: What Should Elegoo Fix/Add in the Saturn 5?
Return to the Saturn 2/3 formula... Saturn 3 with the amber 8K LCD. Fix AA, especially with GOO. Built in heater, chamber heater probably so it warms the build plate as well. Nice to have: flip UV cover. I help a lot of people troubleshoot printers, and there's been a lot of that ever since the Satu

close to giving up
The problem with elegoo resin especially the 3.0 abs and the 8k abs stuff is it's very low quality as reflected in the price for example I can buy 1000g of 8k abs from their official Amazon store for £11.99 and I get 2000g of Elegoo transparent abs for free! Their only truly good quality resin is th

Saturn 4 Ultra Horrible Build Quality, Better Alternatives?
I'm returning an Elegoo Saturn 4 Ultra 16k as it had so many issues right out of the box. It arrived with the lcd touch screen not connected. The hopper mechanism was installed incorrectly (made incredible bang noises on the self test!!) and looks like it damaged the limit switch. Elegoo support wer
