06 Molding and Casting

I am making a relief sculpture of myself (3d printing assignment) with mold this time

Making the mold was very successful. The main trick is to make sure that the materials are mixed properly and air bubbles are removed really quick, so the composite can still stay in a liquid sate while pouring it to the CNC routed positive model.

After 3 hours, I could try casting.

I also wanted retry an old project I've done last year: http://www.sangww.net/2014/01/ice-9-spyware-vonnegut-inspired-spy.html

Work-in-progress yet. Instead of making a full-sized knife, I tried making a smaller one.
