In this video, I’ll be making a multi metal puzzle cube that I designed in fusion 360. Its similar in shape to a Rubik's cube but is not solved in the same way. First I 3-D printed the puzzle pieces on my Prusa 3-D printer using a special filament called Polycast. Then I coated the pieces in a ceramic material, called Suspendaslurry. I burned the plastic filament out of the shells in my kiln, and vitrified the shells. I melted copper aluminum and bronze, and filled each shell with a different metal. Then I broke off the ceramic material to reveal the castings. Once the castings were complete, I spent several hours sanding and polishing them. I also made a bronze base and wooden stand to build the puzzle pieces on.
