Any drone / UAV builders in this forum?

with PLA you´ll run into this problem, ABS is more brittle (in my experience). ABS can be actetone fumed, I haven´t found a good smoothing agent for PLA but a little heat helps. It´s not optimal, but you can print molds and cast stuff out with other materials.

And you can always apply some epoxy type and sand it, although it adds weight.

Edit: Totally forgot about CLIP and similar 3D printing techniques. Perfect surface finish, don´t know the stability..
