Cornell Researchers Create Replacement Ear Using 3-D Technology

According to CTV News, a research team from Cornell University have found a way to construct an ear replacement by using a 3-D printer and injections of living cells. The Cornell team starts with cartilage grown from a cow then takes a picture of the person’s ear with a rapidly spinning 3-D camera, which then prints a soft mold of the ear through a 3-D printer. By injecting a collagen gel that’s full of the cow cells that produce cartilage, it then takes a few weeks to grow the cartilage to replace the collagen.
