They worked with Hive-76 to modify a 3d printer to print sugar. The plans and details are open source. Maybe put it on the list for te second experimental printer?

Scientist and open source 3D printing champion Dr. Jordan Miller gives a great talk giving the story of the inspirations that brought him to uniting 3D sugar printing and regenerative medicine.

From the video description:

Using simple yet illustrative analogies to help non-scientists understand his scientific discovery process, Biomedical Researcher Jordan Miller explains to his young audience how he developed vascular structures through 3-D printing. This exciting research is an important complement to advances medical researchers have made in 3-D printing bioidentical human tissue and organs in the lab. It’s a remarkable prospect for the future of organ transplantation.

Deriving inspiration from a cross section of bread and the sugar structure arcing over his dessert, Dr. Miller describes how he combined his background in regenerative medicine, a passion for the maker movement and reliance on worldwide open sourcing to develop viable 3-D printed vascular systems that he demonstrates actually transporting blood.

Jordan Miller, Ph.D. http://twitter.com/jmil is a post-doctoral researcher in the Tissue Microfabrication Laboratory at the University of Pennsylvania. Involved with the 3-D maker community since its infancy, Jordan uses a 3-D printer in his work in biomedical research and regenerative medicine and credits open-source collaboration and the maker movement as important contributors to the success of his research.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
