A 3D printer that can produce sweets using chocolate or sugar has gone on display at the Consumer Electronics Show.
The countertop Chefjet was unveiled at the show in Las Vegas yesterday by American technology firm 3D Systems, which already produces printers for plastics, metals and ceramics and whose founder Chuck Hull invented stereolithography, one of the most popular methods for additive manufacturing.
The printer uses chocolate or sugar as the medium for printing objects, flavoured with vanilla, mint, sour apple, cherry and watermelon flavours, and is capable of creating complicated shapes that are usually difficult to mould.
While the standard model can only produce monochrome creations, the bigger and more expensive Chefjet Pro can churn out treats in full colour using an inkjet head filled with food colouring instead of printer ink.
And Kyle von Hasseln, the co-founder of Sugar Labs, who designed the prototypes for the printers, said they would one day be in family homes.
Standing in front of a printer creating a chocolate sculpture, he added: "These are the very first commercially-certified, kitchen-ready 3D food printers.
"We spread a very fine layer of sugar and cocoa powder and an inkjet head that is just like the one in a desktop 2D printer squirts out cocoa butter and makes chocolate in real time and creates a chocolate sculpture in real time.
"The geometry is very precise and very mathematical and that is traditionally a very difficult thing to do with frosting or chocolate, and can't be done with a traditional mould. We can make interlocked shapes which is a very exciting possibility for candy."
Both printers are expected to go on sale in the second half of the year, with the Chefjet priced at $5,000 (£3,034) and the Chefjet Pro at $10,000.
"One day they will definitely be in homes, these first ones are commercially-certified professional printers for bakeries and restaurants,” said von Hasseln. "But any kind of food is very possible to 3D print, anything that can be powderised and printed, so savoury is in the future for everyone."
The printers will be accompanied by a Digital Cookbook to help customers make the sweets.
