Elegoo Mars 5 Ultra detail test – 25 micron layer height (ABS-Like 8K Space Grey)

Detail with any resin 3D printer hasn’t changed much since 4K came out, Imo. I recently “upgraded” from the Mars 3 to the Mars 5 Ultra and the difference is imperceivable to the eye. The only things that are different is slightly faster prints which doesn’t impress me, an AI camera that doesn’t dete

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. You might be able to reach out to elegoo support and see if they have any any left but usually screens are only available for around 3 years post laun

Looking for a printer need suggestions.

id stay away from the saturn 4 ultra. flawed design for a large capacity printer as you will drip resin all over that thing when removing those large prints, probably hollowed, meaning resin will start POURING the moment you change orientation of that plate while removing it. Elegoo's "solution" is

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.
