Markets in Everything: 3D Chocolate Printer

BBC News -- "The UK 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. It would allow chocolate lovers to print their own custom-made sweets, layer by layer.

Lead scientist Dr Liang Hao, from the University of Exeter, founded the Choc Edge company to commercialize the device after interest from retailers. 3D printing using plastic, wood and metal is already widely used by industry to create objects ranging from jewellery and footwear to human bones."
