Saturn 4 Ultra

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

Saturn 4 Ultra 16k and the 8k Standard Resin from Elegoo. No special settings. The printer is just incredibly good :)

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

Thanks! I’m using a Elegoo Saturn 4 ultra. That model using a different type of FEP film that helps to blend out layer lines. I also set the layer height really low. My print times are outrageous for the size but I have two Saturns so that makes up for it. If you’re completely new to 3D printing, I

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)

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.

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

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

Basically, uncured UV resin is toxic for your skin and can lead to itchyness, rashes or an allergic reaction. So you must wear gloves when handling it in liquid form (which is what you pour in the vat) and then rinse the printed models in 99% IPA and given them a final brief UV cure to get rid of an

Did it start to fail at the back and split moving forward like this? https://www.reddit.com/r/resinprinting/comments/1n8gh14/help_with_st_flex_black_70a_parts_of_print_stop/ If so it is partially because the resin stretches and the tilt stroke of the S4U is shorter at the back than the front.
