Learn Resin Casting Techniques: Cold Casting

Hackaday: Sometimes we need the look, feel, and weight of a metal part in a project, but not the metal itself. Maybe you’re going for that retro look. Maybe you’re restoring an old radio and you have one brass piece but not another. It’s possible to get a very metal like part without all of the expense and heat required in casting or the long hours in the metal fabrication shop.

This is super interesting. I never thought props/cast making people would actually need to replicate metal without using metal; I assumed one would either just somehow make the piece out of metal again, or they would make the piece out of plaster or resin and just paint it. Adding in a metal powder is a super smart idea to avoid complicated metalwork but still incorporate real metals into the piece. The part about the dangers of metal powder was freaky though; I can't believe aluminum is linked to Alzheimers disease and that iron can make you almost instantly depressed. That's so scary! I like that the piece was originally fabricated on a 3D printer, because in our mold making workshop last Friday I was told that 3D printing wasn't very practical for a props shop and it confused me. As someone who knows how to 3D print, I think it's a very useful technology to utilize.
