They have developed a unique approach to ‘3D’ bioprinting by incorporating flash freezing into their process. They have improved on current techniques by printing layers of flat tissues [2D] and freezing them until they can be combined into a 3D structure. This technique was developed to overcome one of the major hurdles in scaling up 3D printing: the survival of the printed cells during the lengthy process of printing complex structures. By using 2D layers and flash freezing them before bringing them together to form a 3D organ or tissue structure, the new technique assures the survival of the cells throughout bigger, and more complex organs.

Professor of Mechanical Engineering, Boris Rubinsky comments, “The problem with 3D bioprinting is that it is a very slow process, so you can't print anything big because the biological materials will deteriorate by the time you finish. One of our innovations is that we freeze the material as it is being printed, so that the biological material is preserved.”

UC Berkeley’s innovative research demonstrates the integral role stem cells are playing in cutting edge medical care options. By banking their own valuable stem cells, families can ensure that they will have access to these emerging therapies in the near future.
