At the lab we can turn a gray-scale image into a depth-map to control the height of a CNC machine. Combine this with a V-groove router bit and you have an easy way to create intricate shapes and molds. For instance to create stunning cakes 😉
Using the CNC Mill at Fablab013 a pattern was carved in 2.5 D out of a large sheet of acrylic (Food safe !). The Fondant was rolled and rubbed into the mold and lifted in one to to serve as the cake wrapper. (cake pictures omitted due to hungry testers).
