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

Every print is failing now

My elegoo mars 4 ultra came with ACF from factory. 0 issues with it. All the issues were caused by me being an idiot

Dica de impressora barata para iniciante completos em impressão em geral

That's not an easy market to get into. Are you sculpting your own original creations? The printer is the easy part. Elegoo Mars 4 series is affordable as is Anycubic Photon Mono 4 series. Both good printers imo. It's the cost of the peripherals that you need to consider. Resin printing is not cheap.

Printer upgrade from Halot One?

I’ve bounced between creality and elegoo. The debugging for parts not sticking for a halot lite grew tedious and kept me out for a bit. Now onto a S4U16. It’s a costly way to get good prints with minimal time fiddling. If I hadn’t been in the position to drop $500, I would have been looking at a mar

What Resin printer to buy for minis?

If it's just for minis, printers like the elegoo Mars series are totally fine. Right now I use the mars 4 and I printed 4 armies and 6 warbands in the last 3 years. But it's important to have a place for it. It's smelly and the fumes are not good for your health. Temperature is another problem. Prin

Looking for 1st 3D printer

Best space for resin printer = grow tent with duct fan and ventilation pipe running trough window. Because resin is stinky and relatively toxic as well as solvents. First printer - my favorite is Elegoo Saturn 3 ultra \ Mars 4 ultra depends on size you want. I dont like new gen tilt-vat printers.

My experience with the Saturn 4 Ultra 16K so far.

Totalmente de acuerdo. Con mantenimiento duran... eternamente. Yo, con mi última elegoo mars 3 pro estuve imprimiendo 5 veces o más a la semana durante 2 años. Luego compré la mars 4 ultra hará año y medio e imprimo unas 8 veces por semana. La mars 3 ahí está, con el mismo fep, de repuesto. Y la 4,

Anycubic Photon Mono M7 or Elegoo Saturn 3 Ultra

If the Saturn 3 is available, get that. It’s actually better than the Ultra, despite the internet… has better UV uniformity, comes with nFEP/PFA release film as standard (Elegoo discontinued using ACF after the Mars 4 Ultra and Saturn 3 Ultra). Level using my method and you’ll eliminate Z axis compr

Is this a good FEP foil (140X200MM)? for Elegoo Mars 5 Ultra

Edit: As u/awyeahmuffins pointed out, oddly enough the Mars 4, 5, and 5 Ultra have FEP listed by Elegoo. Didn't realize FEP was still in use on any consumer machines as PFA is better and cheaper. The Mars 4 Max uses PFA and notably has a larger tank than other Mars machines. In this case, either fil

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
