lately I've been getting some pretty smooth and glossy prints using abs. Some pretty wicked curls too on the longer prints too. I think I'm extruding too hot. And my bed won't go over 90c. Some of my abs and pla spools are the same color so I just wanted to know if there was a tried and true method already, other than an electron microscope.
looks like acetone will be my test.
thanks everyone.
