Make 3D Shape in layers on the Glowforge.
Cast that shape in Silicon
Pour Molten Choclate in to the silicon mold
The Smooth on silicon worked perfect. If your trying this yourself use the Smooth-sil 940. That’s the food safe one. The problem was my shape has too small details and too much relief for an effective mold. So I am going to try again soon with a new design.
Failure is the best teacher.
