Personalized chocolate

Source, July 5, 2011: Personalized 3D chocolate

From the article:

A 3D printer that uses chocolate has been developed by University of
Exeter researchers - and it prints layers of chocolate instead of ink
or plastic.
Although still a prototype, several retailers have already expressed
interest in taking on the device.
3D printing using plastic and metal is already widely used in industry
to speed up design work.
Lead scientist Dr Liang Hao told BBC News 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.
"Then you do a 3D shape - layer by layer, printing chocolate instead of
ink, like if you were layering 2D paper to form a 3D shape," he said.
