3D Printed Chocolate: From School Project to Edible Reality

Published on May 04, 2026 | Translated from Spanish

3D printing has moved beyond plastic and resin to enter the world of confectionery. It is now possible to create chocolate figures with specialized machines, such as the Cocoa Press, a printer that Ellie Weinstein created in 2014 as a school project. Designed for chocolatiers, it is also available for home consumers.

How the Cocoa Press works and its technical development 🍫

The Cocoa Press uses an extrusion system that heats the chocolate to a controlled temperature, allowing it to flow through a nozzle. The process requires 3D modeling software to design the pieces, which are then printed layer by layer onto a cold base to solidify the chocolate. Development began with basic prototypes in a garage, eventually leading to a commercial model that handles different types of chocolate, from white to dark, with an adjustable layer thickness.

Finally, a printer that doesn't print useless parts 😂

Finally, a 3D printer that produces something you can actually eat, instead of those plastic keychains you pile up in a drawer. Of course, don't expect to print a full cup of coffee. The Cocoa Press lets you create small figures, letters, or geometric shapes out of chocolate, perfect for decorating cakes or pretending you're a high-end pastry chef. The only risk: that you eat the filament before the print is finished.
