MOLDING AND CASTING

This week, I learned to use 3D machining and OOMOO to make mold and cast with plaster.

After decining to make a topographic map, I downloaded a map from Internet and followed this website to transfer the map into a surface. The transfered map looks ok in general but has too much details. After some searching, I found a 3D model from the Internet and decided to use that directly.

The machining process and modling was smooth. The only problem I met was that I left too thin margin for the walls and the placement was not perfectly parallel. As a result, the wall was broken, and I need to paste a wooden stick to keep the wall stable. After that, reading OOMOO's SDS, making the mold, and making the hydrocal plaster were smooth.

Tools:	Fusion 360, image2surface, Vectric Cut3D, ShopBot, machineable wax, OOMOO, hydrocal plaster.
