Well my first attempt at a practical print didn't go as well as I hoped. Not sure how well it comes across but the flat bit at the bottom is meant to be gears. It's a replacement gear drive for the Nintendo 64 controllers.
I've got a pretty good idea about what went wrong though. It was either me putting more resin in on top of the older resin I used to print the formlabs test rook, which I didn't notice but seemed to have a film of cured resin along the bottom. Empty and clean the vat between every print, lesson learned. Or it was the fact that I printed them vertically, flat on the bed with no supports. I'm willing to bet it was a mix of the two.
Is there a best practice to printing small gears this size? I think the fifty micron layer height and screen resolution is fine, there seem to be a correct number of gear teeth and the sizing seems great compared to an actual gear, just a bunch of resin got cured between them by the looks of it.
It's a shame too because even with the resin being uncured it's sturdy enough to withstand the stresses put on it and a perfect fit for the joystick itself! Just 80% of the way there!
