In the past decade, UC San Diego engineers have 3D printed a variety of devices ranging from rocket engines, to robots, to structures inspired by the seahorse’s tail. Now, nanoengineers have added a new item to that list: a 3D printed blood vessel network.

Emily Callahan, MAS ’14, and Amber Jackson, MAS ’14, two alumnae of Scripps Institution of Oceanography, have made it their mission to determine the best possible afterlife for these rig structures.
