Jonathan Russell, who calls himself TechWiz, is a graphic designer and web developer who lives near Sydney, Australia, and he operates a website and a YouTube channel under his TechWiz brand. One of his recent posts is an examination of alternatives to using acetone to smooth his 3D printed models. Russell says he wasn't happy with cold vapor smoothing with acetone or the hot method of that technique, so he tested out smoothing using epoxy instead. Russell uses Z-Poxy PT-39 30 Minute epoxy solution to smooth out his models. You can check out the whole story and see his results here: http://3dprint.com/63408/smoothing-with-epoxy/
