Resin printing "arms race" over?
Same as before. Expect 12 months between cycles. This year was odd, printers got released on a shorter cycle. The Saturn 4 Ultra 16K was probably supposed to be the Saturn 5, but Elegoo released it early (only 7-8 months after the Saturn 4/4 Ultra). Probably because Uniformation was releasing the 16

I have my own (mini) Rocky! 🥰
Thank you! I currently have an Elegoo Saturn 4 Ultra printer, which I recently upgraded to from a much smaller Elegoo Mars (first generation). It's been pretty much foolproof since I bought it, once I'd manually levelled it. I also have the Elegoo Mercury Plus v3 wash and cure station, which has hug

Why does this keep happening to my prints?
Yes, this would/should apply to all printers. The "tilting VAT" feature is merely a different way to separate the models from the release film but this doesn't change that the layer is still printed on the release film and therefore sticks to it. In addition, those newer Elegoo printers use a better

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

My favorite reviews <3 I love my customers!
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

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

Layer lines.... Going snaller layer height vs Antialiasing?
It's a Saturn 4 Ultra 16k, and I used the top rated 30um profile in lychee for Elegoo ABS-like 3.0 8K, and printed solid with medium grid supports and manual orientation. I also used the GPU based anti aliasing option. Total print time was 10 hours! Full disclosure this is with a coat of primer. Att

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
