I think the only reason I might consider getting a SLA printer in the future is for making buttons, switches, and very small mechanisms. FDM is not very good for these in my experience so far, though I haven’t tried to print them with something like a 0.25 mm nozzle yet. The interface angles and texture have a very large impact on how a button slides into a small button on a circuit board and or is even more sensitive when the printed button is depressing a metal switch dome on a PCB.

Are there any really small SLA printers that have a rigged open tool chain for such an application? I care about stupid-tiny types of things like the buttons on the side of a phone.

On my bucket list is to etch my own 4+ layer circuit boards and make some really small stuff at home just to say I can.
