I have made some figurines 4-5cm in height, with some random PLA, maybe it can serve as example for you... Btw, what do you mean by 1:72?
1 length unit on the model is 72 length units on the real object. Figures are about 2cm tall.
Huh, 2cm in height.. I have twice as much height there and it was very difficult and time consuming to remove supports, also the figurines are very fragile, I can imagine that 2cm figurines would be even more difficult. If you have two nozzles on the printer you could use the second to print water soluble support material
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!
These are supposedly 1:72 resin figures. (No clue what printer, though.)

Look a bit rougher than injection mold, but for wargaming purposes this would be absolutely sufficient.
Yup, looks like resin to me. But I agree, they're good for wargaming
Those are resin prints, not FDM prints. The print technology (FDM vs resin) is the bigger factor than the actual plastic used (PLA vs others).
And that level of detail is impossible with FDM regardless of the plastic used.
Yes, my post says that they are resin.
