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
Silicone casting rubber,
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
Pretty self explanatory...
Step 3: Cast Your Part
Use double sided tape to stick you part to the bottom of a container, and fill it with rubber. Wait the required time for it to cure.
Step 4: Prepare Your Mold
Squeeze the sides of the cup to release the mold, then cut the sides of the mold to release the part.
Zip tie the mold back together
Step 5: Cast Your Parts
Melt your metal/wax and pour it into the mold. Wait for it to cool and harden.
Release the parts from the mold and pull them out.
