Molding and Casting

For this weeks assignment, I planed to make a triangle scale, because I wanted to investigate the accuracy of the final product. In addition to make an idea to be easily reproducable, it can be connected to another peice for your desired times.

Design

I used Rhinoceros to model my triangle scale.

Milling

For milling, I noticed that I forgot to consider the tool diameter, and things did not have efficient space. My outer edge broke.

the Silicone Negative

All was fine with making the oomoo, one thing is that the outer wall was too thin that it can bend easily.

Casting stone

I used the two materials that was provided, dry stone did not dry because I missed the calculation of water. After finishing, I measured the distance for accuracy, and the result was better then my expectations. dry stone seemed pretty accurate. I was not able to connect the two peices, because the joints was too small for a 1/8 ball nose endmill.
