this is a comparison of ways to acetone finish 3D printed materials that i saw other people uses.
And i'm also comparing 2 different materials, ABS and PLA. They say that PLA wont react to acetone, but why not try it anyway.
I printed the form with various kinds of surfaces, edges, points, and shapes to see if the acetone will have different effects on them.
I made this form to see the effects of the acetone on different types of shapes.
