Making ones own wedding rings @ggreer

Geoff Greer is getting married pretty soon, and figured it’d be fun to make the rings.

I’d seen a Nile Red video where he made purple gold, and the process seemed simple enough: Make a mold, pour some molten metal into it, and voila you have metal in the shape of the mold. It turns out that the devil is in the details.

Since I wanted the ring to fit my finger precisely, and I wanted it to be pure gold, I figured that lost PLA casting was my best bet. The process is similar to lost wax casting, but starts with a 3D printed part instead of a wax form.

I’d 3D print the ring I wanted, make a plaster mold of it, heat up the mold until the plastic melted/vaporized away, then pour molten metal into the mold. After it cooled I’d rinse away the plaster, then cut off the excess metal and polish the ring.

Check out the process in the post here.
