molding and casting
This week, I used the 3-axis CNC milling machine Roland to mill an object (variant 1), which I later cast in silicone to create a cake mold for pastry. I was inspired by a video from a pastry chef and was eager to try it out myself . Whether it was a good decision, you will find out soon.
To make a better comparison between a CNC-milled object and a 3D printed object (variant 2), I tested both methods. This allowed me to better understand the differences in processing and results.
For the project, I used the following materials:

I’m excited to see how the final result turns out! Stay tuned to see how the CNC-milled form compares to the 3D-printed one.
