About

For the eigth week, we had to mold and cast something. This was particularly exciting to me, as my project for 3.042 (the course 3 capstone) involves the casting and curing of diferent materials onto a glove. For this reason, I was excited to create a different mold and cast that. Sadly, I was not able to make something too complicated, as I had Bronchitis and could barely think/ couldn't leave my room for most of the week.

In the end, I decided to just make a ball, since I figured I could use it as a paperweight. In Fusion 360, I CADed the ball. It took a lot of tries, since I wanted to make the process as efficient as possible, so I wanted to ensure that I cut as little as possible. So I created a ball with a 20mm diameter. I then had the cylinder diameter 13mm connected to it, which seemed a little big, but I didn't realize until after I made it. I also ensured to add 4 mini circles on the edges of the square, to ensure that I could perfectly line up the sections. One side of the mold has the circle concave and the other convex.

In the end, it appeared that I did not mix perfectly the oomoo in a ratio of 1:1, so after 1 hr it had not fully cured. However, I decided it seemed good enough, so I poured the hydrostone into the mold. Sadly, once I used the rubber bands, the oomoo deformed a lot, leading to the creation of a head looking structure as opposed to a sphere. I also know that it was not perfectly cured, as when I came back, both sides of the mold had cured to each other.
