You’re going to want to consider layer height. The layer height on FDM printers can be set usually between .12mm to .28mm. You need to look at your models and their actual sizes and see if any features will fall within that range. Depending on the print orientation, those will likely not resolve.

If you want higher resolution, you probably want a resin printer. They have more fidelity through screen resolution and the layer height can generally be between .025mm and .1mm. But they’re more expensive and the resin is more expensive than just about any filament.

For 2cm model with a .2mm layer height, you’re looking at like 20 layers with an FDM printer. With a resin printer and 0.5mm layer height, closer to 50 layers.

With a 2cm tall figure, in my opinion, you’ll have issues getting the resolution you want on any printer. Expect to spend a lot of time troubleshooting and calibrating and troubleshooting and recalibrating.

I’ll be happy to be proven wrong!
