12. Molding and Casting
This week assignment was to design a mold and use it to cast parts.
Mold planning
For this week's assignment, I decided to create a mold to make chocolate figures. In particular to make chocolate in the form of Darth Vader's helmet. This meant I had to make a mold that would be refrigerated to obtain a solid product, in order to accomplish this I needed to essential steps. First I had to design a first solid mold, this mold would use a "positive" figure of my design in order to shape a second mold that would be my final mold. This is due to two main reasons, in order to make it easier to remove the mold once the chocolate helmet is done I need the mold to be soft, the second reason is that I needed a special material for a mold that is going to be used on food, so I couldn't use resin or simple wax.
Designing my mold
To make the first mold I used a solid wax block for carving, and then I took its measures, first I created a simple block with the dimensions of my wax block, after that I used the top of my block to create a sketch for two holes were the parts of the Darth Vader helmet.
Once the carcass of my mold was done I saved it as an STL and then imported it to a blender were I added Darth Vader's helmet to my mold.
