Incredible 3D Printer Can Make Bone, Cartilage, and Muscle
"A team of biomedical researchers at Wake Forest Institute for Regenerative Medicine has just completed an invention 10 years in the making. It's a 3D printer that can craft relatively simple tissues like cartilage into large complex shapes—like an infant's ear. Using cartridges that are brimming with biodegradable plastic and human cells bound up in gel, this new kind of 3D printer builds complex chunks of growing muscle, cartilage, and even bone. When implanted into animals, these simple fabricated tissues survive and thrive indefinitely. "
