I will teach you how to cast a 3D printed part out of silicone and mold it out of wax, metal, etc.
BTW If you could please vote for me in the 3D Hubs 3D printing contest I would really appreciate it!!!
Step 1: Materials Needed
Metal ( I like to use bismuth because it has a low melting point. It's also cheap, you can buy it as fishing sinkers, then just melt them down into an ingot using a cupcake pan and a mini torch.),
Double sided tape
A cup or other container
And of course, a 3d printed part
Step 2: 3D Print Your Part
Step 3: Cast Your Part
Step 4: Prepare Your Mold
Zip tie the mold back together
Step 5: Cast Your Parts
Release the parts from the mold and pull them out.
