Scientists Build Vascular Network Using Sugar and a 3-D Printer

3D printing replacement blood vessels!

Researchers at University of Pennsylvania say they may have found a way to create vasculatures using sugar and a 3-D printer. The design starts with sucrose and glucose and, with a custom RepRap 3-D printer, the scientists were able to turn the mixture into a free-standing, three dimensional vascular template.
