Hybrid 3D printer produces implantable cartilage

Generally speaking, injured cartilage doesn’t heal well ... if at all. In recent years, however, scientists have successfully regrown cartilage at injury sites, using things like hydrogel, microspheres and collagen-based nano-scaffolding. Now, a team of scientists led by Prof. James Yu of North Carolina's Wake Forest Institute for Regenerative Medicine have developed something else – a 3D printer that creates implantable cartilage.
