Replacing FEP with ACF
ACF has it's downsides, namely causing fine vertical lines on smooth surfaces. There was such a backlash against it, Elegoo stopped using ACF on new printers. No Mars 5 or Saturn 4 model uses ACF. nFEP/PFA however is a straight upgrade from FEP, and is cheaper than ACF. And yes, it uses the same ten

New to Resin - which saturn?
Generally speaking the Saturn 4 Ultra 16k is the best option for most people. I investigated and wrote the original post explaining the 3-bit grayscale deficiency and it is still present. I also bought a S4U 16k and subsequently worked out a dithering method with UVTools to restore a significant por

Elegoo Saturn 4 Ultra 16k - Water Washable
I'll just assume it bots or something, but for whatever reason, this thread is just filled with wrong answers. Well, technically the Wait time before print suggestion is correct, but is still useless because it fails to provide any guidelines for settings or why it works. Rest / Wait time is why you

Saturn 4 Ultra 16K, over a year of troubleshooting and I still can't fix it.
The S4U springloaded plate means that wait times are even more mandatory than regular printers. The light turns on way before the resin has settled and the springs have found home. This means you get a layer thicker than supposed especially at 20um, your bottom layers are probably closer to 0.5 or e

What is the BambuLab A1 of resin printing?
At the price point, the Saturn 4 Ultra 12k or 16k are $800-1200 of machine for $400-500. It and Heygears (at that $1200+ price point) do the most to absolve the user of tuning a dozen speeds and feeds for the Z-axis movement / release & retract cycle. Heygears does this by having their slicing and p

FDM vs Resin printed mini's - a noobs visual reference.
That's what I was thinking. I dont know if it is the water washable resin or what, but my wife and I started with resin printing with the Saturn 4 Ultra, and it prints amazing detail with out of the box functionalities. It generally either fails to print entirely or prints beautifully. Larger pieces

Photon P1 vs Saturn 4 Ultra 16k
No build plate flatness issue with the Saturn 4 Ultra outside rare individual defects, but it will typically not achieve 100% perfect Z accuracy the first several layers. You will want to use a high amount of Rest After Retract (Chitubox) / Wait time before cure (UVTools) using UVTools for the first

how reputable are elegoo printers?
The story people keep trying to spin about the frequency of problems with the automatic leveling build plate simply ignores scale of how many S4Us are out there in use. And there is a very simple solution with increase Wait time before cure for the first 10 or so layers. The Saturn 4 Ultra 12k and 1

Have fun with it! The print quality seems nice and sharp. And yes there are design flaws, but they're on every printer (Elegoo Saturn 4 ultra build plate for example)
