pretty much the same as for regular printers.... XY resolution and Z resolution are typical. However, having said that, your results may vary... the resolution of the stepper motors (or laser) may well exceed the resolution of what can be accurately laid down, and certainly the minimum thickness of a single line of material may be considerably larger than that of the minimum resolution achievable kn a given surface.
that is all before you start talking about the actual achievable quality of different configurations and technologies. laser stereolithography should be higher resolution than filament for example.
I've only seen "production like" finishes achieved on top end industrial machines. that requires resolutions around 30 microns and consequently slow build times.TANSTAAFL
