3D printed 5x F1 fitted to Dragon Saturn V in Real Space Modeling Posted July 2 hmmm....that's a good question. I actually haven't run any tests to see the thinnest that would hold up but I may have to do that. perhaps a line up of sheets on end at various thickness and angles to see what it can do. I'm always leary of doing these kinds of test for not wanting to "waste" material. But if I were smarter I'd realize that the actual waste is not knowing what it can and can't do and trying to print things that fail.
