ABS would pose a few problems…its possible but finding a suitable abrading material would be the trick. Only because of ABS having a higher impact rating

I was going to try sandblasting PLA since my friend has a sandblaster. I never got around to it. Glad someone did.

Now to find a way to build a home made sand blaster. Also, it’s too bad he didn’t try to touch up the end result of the gray one with a light flame or acetone to bring back the black.
