Saturn 4 Ultra 16K

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'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

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

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

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

I recently found this as well. It appears recent firmware to avoid the "lasagna bug" is either skipping layers or skipping the gray pixels when it can't load the image to the LCD fast enough. I have similar results with my own experiments in vertical smoothing / AA here: https://www.reddit.com/r/res

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

Hmm, not what you want to hear but my Saturn 4 Ultra has been rock solid, I just hit print. I am using Elegoo Satelite for slicing. If you haven't tried it, do it. It is free and easy to use. Are you rotating your models so they are at a angle? Use ChatGPT to help with settings. You can take a photo

The 16K printers are all limited to 3-bit greyscale due to the LCD controller. The exception is the Athena 2 that has a custom LCD controller. All Anycubic printers are limited to 4-bit greyscale die to Anycubic’s firmware/motherboard limitations. Previous generation printers from Elegoo and Phrozen
