The world of 3D printing is getting a lot tastier. Waterloo-based Structur3D Printing founders John Mardlin, Andrew Finkle and Dr. Charles Mire have developed a paste extruder that goes beyond plastics for its printing materials. The company says the device, which can be added to most existing 3D printers, can print in various pastes, including icing, silicone, wood filler and even Nutella. Beyond the obvious joys of creating your own edible objects, it could make the process more affordable, depending on the material you’re using. Bet it’s got you licking your lips.
