Chocolate Printer to Go on Sale After Easter
The U.K. scientists who developed a prototype chocolate printer last year say they have now perfected it. They hope to have the machine on sale at the end of April, just missing the Easter egg rush. Lead scientist Dr Liang Hao, from the University of Exeter, founded the Choc Edge company to commercialize the device after interest from retailers.
Dr Hao told the BBC that chocolate printing, just like any other 3D printing technique, starts with a flat cross-section image—similar to that produced by ordinary printers turning out images, and then prints out chocolate layer by layer to create a 3D shape.
