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

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

All printers need more Rest After Retract (Chitubox) / Wait Before Print (Lychee) / Wait time before cure (UVTools) for the base layers. Your adhesion failure here is because your raft is printed with over thick layers. Almost looks like the raft was failing to adhere from the start or isn't actuall

That will be a screen replacement. And, yeah it's getting too common with the S4U just past the 1 year mark. Here's my theory on the source of the problem - bad software configuration of the automatic leveling system and lack of a baked in Rest After Retract along with a couple methods to prevent th

Just going to copy-paste my comment from a couple weeks ago on the matter of S4U dead LCDs: For you next LCD, definitely look into use Rest After Retract (Chitubox) / Wait time before cure (UVTools name) via UVTools for the first 20 layers or so like the following settings: https://www.reddit.com/r/

I was going to ask if it was a Saturn 4 Ultra with the crazy thick raft you've got going on in the first picture. When you let it print rafts that far over thickness (what is that 1.7-2.1mm for a 1mm raft?). Your LCD has pressure spot failures, and it is likely because the build plate and overly thi

I'm having the same issues as this guy it was working fine yesterday but now stuff won't stick to the plate I changed the fep about a week ago and its only been through 10k cycles Im using a saturn 4 ultra 16k and my exposure times are set the way elegoo wants it im using 8k 3.0 resin which I've bee

TL;DR: The Saturn 3 Ultra is a bad value, the Saturn 4 Ultra is an ok value. Best value is the Saturn 3 non-Ultra. Phrozen is Elegoo and Anycubic quality at twice the price. And they generally have worse UV light uniformity. And their support sucks. As a former Phrozen owner, was glad to get rid of

Why Elegoo did not include at least the following features for the saturn 4 ultra 16k, i don't think it would drastically increase the price:lcd screen swap new vat for faster fep changes manual leveling

If the Saturn 3 (non-Ultra) is available to you, it's the best bang for your buck and last of the non auto-leveling printers worth buying. Usually less than $270. Heygears is running a sale on the Reflex RS for $499, which is the lowest that printer has ever been. It's probably the only auto-levelin
