I thought the same thing… for a time, but after sending them my models, and trying to orient it several different ways, testing different support settings, basically everything in the book to get the minimum size print I needed, the part would fail. It’s nice you managed to get something that large, but I guarantee the slices had small surface areas. I got some prints to complete with multiple parts, and it had no problem with tall skinny parts. Bottom line is though if the area of a single slice gets too large, and this is a commonly known problem with the peel design SLA 3D printers, the print will either not completely separate from the tank, or cause the printer to bounce and throw things out of alignment. I exhausted every possible option for model orientation and support structure before I gave up on the printer. If this design worked so well, and I was wrong, and it was just user error that caused this problem then they wouldn’t have backed down, and would have stuck to their guns, and not buckled at the first breath of me challenging them on it.
