Oh another question, when I cast in metal using lost wax will the infill percentage translate the same into metal? Like will the center of the cast have air pockets or will it be completely solid?by kug - General
Lol @ acetone vapor - that sounds either very highly toxic or flammable... can you give more detail? I'm using a Replicator 2 (I know wrong place, but you guys have a bit more activity) so not sure if I can use ABS..by kug - General
Hey, so I'm using my 3D printer to creat jewelry, and it is a bit of a pain to sandpaper smooth, any ideas on the best way firstly get the layer lines/resolution removed, then to polish it up to a shine? Could I use a dremel with a fine abrasive tip? Any ideas on what sort of part I'd need?
