Chocolate- and/or sugar-extruding 3D printers have existed on the margins of the pastry world for a year or two. Beginning this week they may just become commonplace, following 3D Systems’ unveiling of the ChefJet at the Consumer Electronics Show in Las Vegas. The cheapest models cost about $5,000, which means only high-end pastry departments will be able to afford them for now. And maybe that’s for the best. I’m not sure I’d eat something like this in front of the TV on a Tuesday night. Photo from Make Magazine.
