3D Printed Ice Cream

The Guardian has reported, “Kyle Hounsell, Kristine Bunker, and David Donghyun Kim,…three students from Massachusetts Institute of Technology (MIT) have hacked together a 3D printer that can produce edible Mr. Whippy-style ice cream in any shape.”

This contraption is a “modified version of an existing 3D printer connected to a ‘soft serve’ ice cream machine – as part of a graduate project in MIT’s additive manufacturing department.”

According to the students, “first, we needed to print into a cooled environment so that the ice cream would hold its shape once printed.  We bought a small upright freezer which was large enough to both put the Solidoodle inside and allow for the full build volume we were aiming for.”

They “built a cooling system using liquid nitrogen to fix the ice cream in place as it was squirted out of the 3D printer’s nozzle into the desired shape.  The instant cooling allowed the printer to build up the ice cream layers just as a traditional extrusion-based 3D printer squirts down layers of plastic.”

This is a proof-of-concept printer and “needs refinement before it is likely to see commercial duty, but the technology could appear in an ice cream truck near you soon, if the students or a third party decides to continue developing the system further.”
