Three students at MIT, Kyle Hounsell, Kristine Bunker, and David Donghyun Kim, have created a homemade ice cream printer that extrudes soft serve and immediately freezes it so that it can be layered on a cooled plate, and was recently featured in TechCrunch. The group designed and fabricated this contraption as part of John Hart’s Additive Manufacturing class 2.S998, a new graduate class on additive manufacturing, with graduate student Jamison Go as lead teaching assistant.
