This is very true, I tried to print some figurines using filament, and it was a total disaster. I'm sure there are some figures and some settings of slicer and printer that work, but just grabbing a fig and printing it isn't the same as grabbing other things and printing them. My experience based on 5-7 spools of filament printed through a rather enhanced Ender 3 Pro (+BLTouch, MicroSwiss, new mobo, dual gear extruder, upgraded bed springs).

Though, as others here mentioned, resin may not be what you want either. I looked at them briefly when my son was interested in painting minifigs, and decided I didn't want to deal with resin and I DEFINITELY didn't want him working in resin, based on the messes he makes with cereal.

Resin is really nasty stuff though. Many folks may not want to deal with having it in the home and disposing of it.

It depends on the scale. I'd imaging GI Joe/Barbie scale you want FDM. Minis for D&D you want resin.

Not to mention, way cooler to watch while printing.
