Rep Rap 3D Printing Blood Vessel Networks

A major challenge in tissue engineering is the integration of blood vessels among cells to uniformly supply them with nutrients.

Researchers from University of Pennsylvania and MIT just reported in journal Nature Materials the ability to print 3D filament networks that may serve the role of vessels in the future. They implemented the open source RepRap 3D printer with a few of their own changes, including a customized extruder and control software.
