On the issue of black, I agree. I have not had a formulation of Formlabs black that worked, consistently.
I voiced my concern via a troubleshooting ticket and moved on…right to the Grey V4 and haven’t looked back.
I have not had a failed print in Grey V4 that wasn’t due to an error of my design. Either in not using enough supports (trying to save on post clean up) or not checking the tank’s clarity first. The Grey V4 is my go-to resin followed by clear and then white.
I print parts that have very thin walls, 1.0-1.5mm and some overhang. I am unable to post images due to copyright but I’m not just printing big things lacking fine details. If that were the case, I’d have kept my FDM printers.
