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

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

Mars 4 Ultra build plate does not fit in Mercury version 2.0
I meant Elegoo. I was using speak to text lol. And yeah it barely fits in, even at an angle. That washbin clearly isn’t meant to be used with the Mars 4 Ultra. Even though the bundle advertises 2 ways to clean (model separate, and model on build plate).

Prints Partially Peeling from Build Plate
Same issue here. Over 25s, it's nearly impossible to remove the bottom layers easily. While having the same issue as op mentioned. Elegoo support team is aware...and we have no clue about how to fix this. Mars 4 ultra user

how reputable are elegoo printers?
I'm not convinced Elegoo or Creality are very good companies after owning a Mars 4 Ultra for two years that I have to re-level way too often, and struggling with the scan software that appears to have been written by a 4th grader. Their products aren't all bad but their customer service so far has b

Printhead PCB borked.
That’s precisely what I didn’t say or suggest. I don’t think Elegoo are horrible. I certainly don’t think the CC is trash, because it’s nots and I think their customer support experience is generally very good, and I have 6 Elegoo machines and every time I’ve had an issue they’ve been very helpful a

Found. It was still one piece until one of my kids picked at it.
Same-mine’s Resin not Filament (Elegoo Mars 4 Ultra), and while the layers are a lot smaller they’re still present and somewhat visible

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

Mars 4 Vs Mars 5
You can just use the mars 4 not ultra fep :) Same vat same screen. ACF is what i meant cfa was a typo sorry :) ACF is much more expensive than pfa or Nfep, it supposedly helps with peeling force which means faster print,but is completely cloudy and results in less sharp prints. Part of when elegoo s
