This week is very exciting. I wanted to make a mold for Jibo and gift it to all PRG members. I was also on a very tight deadline since I was flying for a business trip just before the lecture date. So, I designed my fusion model. I made sure that the Jibo model was in two parts and would be aligned together with a small hole to pour the material in. I designed it for milling, but the line waiting for the milling machine was too long for me to wait, so I printed it with the 3D printer. I followed the instructions in class to create the mold and used liquid plastic to do the cast. I was too slow with the liquid plastic; it hardened while I was pouring it, so I had to do another round.

For my first design and print, Jibo wasn't aligned by a few mm.

So I redesigned it to align them and have opposite holes to keep it together.

I molded the silicone material, and taking it off was very difficult. With the eb7ar logo, it was even harder, given the small details. You can see it being cut off.

I cast the liquid plastic and took the cast off.

Some silicone parts stayed on the cast because they were too small.

Jibo mold was perfect, but I wasn't!

The liquid plastic seeped out because I didn't use the presser/holder to keep it from seeping.

So, only Jibo's head was cast. It looks more like an Alexa Dot.

I'll do the Jibo cast again and fix the issues. I'll have to think about how to post-process the material for finishing, and how to color Jibo. Liquid plastic might not be the material I should use for this project. I cannot wait to create the casts.
