Hello everyone. I've been wanting to find a way to make my prints look really smooth, and I've somewhat hit a snag. I want to be able to polish the colorfabb metal filament, which I know is usually done by rock tumblers, but I also want to be able to smooth out regular prints, which it seems a sand blaster is best for. My question is whether a rock tumbler will be able to smooth prints or if a sand blaster will be able to polish prints? I doubt sand would work, but some other medium probably will. Any ideas would be great. Thanks!
