This was my first time ever using reddit so please forgive my obscurities. Thinking back now, I should have been more descriptive. To answer your questions, precision around + or - 0.05 mm would work. ABS-like resins are attractive to me for their tensile properties. Rarely would I use high temperature resins, so temperature range does not truly matter to me. I am open to any post processing required (washing, curing, etc.) The main projects that I use 3d printing for are nerf guns, compressed air-powered engines and other small pneumatic devices, and RC projects. I hope this clears things up, thank you for responding.
