Notre Dame Engineering and Harvard Medical School collaborate on 4-year NIH project to create lab-grown organs

A visualization of the Hybrid Multi-material and Multi-scale Autonomous Printing technique, which produces 3D complex and hierarchical vascular structures. While scientists have successfully printed small patches of human tissue, scaling those tissues into full-sized organs has remained elusive. In natural organisms, every cell must be within roughly 100 to 200 micrometers—about the thickness of two human hairs—of a blood vessel to receive oxygen and nutrients. Without this intricate, life-givi
