I was researching the type of plastic that the “hockey pucks” use and it is acrylonitrile butadiene styrene (ABS). It has a melting temperature of 221 * F and is relatively close to acrylic plastic, which has a melting temperature of 212*F. During this process I was also researching how to best polish the plastic. One way included sanding down to 1000 grit sandpaper and then adding a wax on the surface. Another idea was flame polishing. This was first tried and burned the plastic and I plan on making another trial. Another idea was using a chemical compound from a manufacturer for ABS plastic. I will then apply each type of polishing to different parts of the “Hockey Puck” and cast a mold. to see the differences.

You may want to talk to the folks across the hall in EDPC. The extrusion printer they have uses the same material and they have experience polishing it. I think one of the fellows told me they use heated polishing, but I don’t know details.
