One of our first thoughts when we realized we could make molds out of machining wax was food. Chocolate, ice, candies of all kinds. Our first test was a series of chocolate candy bars.
The design for the chocolates was made in Rhino.
Our intern Jake made two cute Pacman based designs, one of the ghosts and one of Pacman himself. He machined the molds out of machining wax using a 1/32” end mill. They came out quite nice. Machining wax cuts beautifully on the Othermill. We made the actual molds out of food grade silicone. We used Silicone Plastique, a food grade silicone putty. Next time we would use poured silicone so the mold would be cleaner. However, the molds came out pretty nice and once we made chocolate bars you couldn’t see any of the blemishes in the silicone.

Once we had our molds, we poured molding chocolate in them. We used molding chocolate so we wouldn’t have to temper it. The molds peeled right off the chocolate bars and they looked and tasted great.
The final mold and the chocolate bar made from it.
