I was thinking of smooth curves.

Judging from the photos, even the expensive print has a voxelized appearance. I've certainly seen that in the one 3D print I've handled too.

So my idea was to print slightly oversize, then mill and polish for perfect curves.



Don't people often just use acetone or another solvent to smooth the surface of chunky prints (outdoors, I hope)? How effective that would be would vary depending on the plastic, but it seems easier than milling (if not especially precise).


Sandpaper? File?


That would have to be a pretty fancy mill then. Any kind of overhang and you won't be able to re-work it without a 5 axis job.

And yes, you've caught on to one of the big issues with low cost 3d printers: surface finish.


There may be places a milling arm can't reach, but if you can do it by hand with a Dremel, you can automate it with a gantry and motors and stuff :)

Seems within the realms of hobbyist attainment. Some kind of rig that works in unison with a 3D printer...


Your hands have an incredible number of degrees of freedom.
