Smoothing PLA
13 August 2013
Just found a great tip over on Hackaday about smoothing PLA.
With ABS plastics, you can suspend the part in Acetone vapor for a while to get a shiny finish, but PLA isn’t soluble in Acetone. It turns out you can use tetrahydrofuran in the same role for PLA. Awesome!
I just ordered some on eBay.
