Upgrading from Mars 2 to maybe a Saturn 3 ultra. Advice?
Because the non Ultra has better UV uniformity (light). The Ultra can also have bad castings in the build plate head and z arm that can prevent you from leveling it. The non Ultra comes with nFEP/PFA release film, while the Ultra comes with ACF. ACF causes fine vertical lines to appear on smooth sur

I bought an ELEGOO Saturn 4 to start a hobby. Almost one year later, it has only printed regret.

Looking for an Elegoo OEM 10.1" 4K Mono LCD or something comparable.
The FEP you can probably get some other generic resin printer film and use that, but getting a replacement screen doesn't really make much sense IMO.

Printhead PCB borked.

Looking at a Saturn 4 Ultra 16K; what wash and cure to use?
Hello, fellow hater of new machines from Elegoo. Elegoo overall not bad. Just those ''new gen'' with bunch of useless features and bugged tech - bad. Saturn 3 \ ultra. Mars 4 ultra. Hell, even old Mars 3 and Saturn 2 = great machines.
