Medical 3D Printing & Bioprinting
Researchers at Rice University and University of Pennsylvania have developed a 3D Printed Implant with an intricate network of blood vessels using sugar and silicone. This implant will deliver oxygen and nutrients to all cells in an artificial organ or tissue implant and thereby, helping them grow despite body liability to supply them.
