I’ve been wanting to try metal casting in printed molds for years, but never had a use for the heavy, low melt alloys that would work in a printed mold. When I saw this mod for anti-backlash weights by Pratyeka in the Tiko 3D forums, I figured I’d finally give it a try and ordered a block of metal.

Vibratory Tumbler – Ceramic
Here’s some pictures from a test using a vibratory tumbler* filled with ceramic media. Some of the ceramic pieces were broken to make smaller pieces.

Here’s the process I used to get the results in the picture. I’m sure there are many ways to do this and I’m still trying different variations, but I’ll describe what has worked so far. I’d encourage experimenting, just be careful when working with alloys that contain lead.
What you need:
- 3D printed part
- rock tumbler
- screw tumber media
