Cast and Mold a 3D Printed Part

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!!!

Thanks!

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.),

Wax

Double sided tape

Zip ties

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.

Step 6: Your Done!!!

What type of 3d printer do you have

[mnmmihir]

It really just depends on the type of silicone you have. I just put a scrap a piece of
Rubber over a flame for
A second and it didn't burn
Or melt, just got a bit weaker and easier to tear.
So I used bismuth. Just check on the box of your rubber or online for the max temp I'm pretty sure aluminium should work but just be careful.

do you know if this will work for metals with a higher melting temperature?
