Ive done some 3d print smoothing with acetone and I love the result, however I dont really like printing with ABS. For most of the stuff I do I dont need the improved resilience. Also ABS smells and loves to warp when printed without an enclosure. I wish you could smooth PLA, well this isnt PLA but the printing experiance was pretty darn close. This is Polysmooth and it was specifically designed to be easy to print and smoothable with simple isopropyl alcohol. Lets see just how easy smoothing 3D prints can be.
