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

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 is an amazing out the box printer. Heated vat, tilt up lid, auto leveling, send through WiFi printing and updating, and auto calibration. I’ve done NO configuration on mine besides inputting my resin type and selecting a community profile with the highest ratings. I use Sun

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

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. Fixes are roug

I got the Elegoo Saturn 4 Ultra 16k, but mostly for the slightly larger print area, heated vat as it gets too cold here in the winter to print in my garage otherwise, and wifi connectivity to make life simpler. I’d imagine you could get similar quality and experience from the Mars line, the Saturn 3

Not sure why the thread is all bad advice, but the biggest fix for poor adhesion with the Saturn 4 Ultra 12k* is Rest After Retract (Chitubox) / Wait time before cure (UVTools) for the first 10-20 layers. This is because the automatic leveling and spring-loaded build plate fail to settle the build p

I currently have an elegoo saturn 4 ultra and an saturn 4 ultra 16k. I get fantastic print quality, ill reply with an image if print quality later. The 16k is worth paying extra for purely for the heated vat.

I got into resin printing with the Saturn 4 ultra 16k and im really happy with it. The heated vat is amazing as I print in my garage and it maintains resin temp. Also the tilting vat peels the model off of the fep instead of just yanking it off. This means that you dont need to fight suction forces
