The ice cream printer was my team's final project for M.I.T. 2.S998 "Additive Manufacturing."  The final project for the course was to focus on and prototype a novel additive manufacturing technique or machine for a material or object not readily produced by current designs. After initially prodding at the idea of chocolate drop in filament for current hobbyist level 3D printers, we settled on attempting to print ice cream. The final iteration of the device used an extrusion system to layer soft-serve-like ice cream onto a computer controlled bed, before blasting it with liquid nitrogen to solidify it. We didn't really anticipate it, but once the media got wind of the project, it went places, including Time Magazine online, many, many 3D printing forums, and... well.... Cosmo?
