New 3D bioprinting method can create organs from collagen

Providers may soon be able to offer patients 3D implants with tissues composed of collagen — the major structural protein in the human body.

Researchers at Carnegie Mellon University have developed a first-of-its-kind technique called FRESH (Freeform Reversible Embedding of Suspended Hydrogels) for designing and composing implants with the protein, based on MR scans of the desired organ. The method is touted by its creators as a step in the direction of developing full-sized, 3D printed, adult human hearts.
