Scientists use 3D printing to help grow an ear
The work reported Wednesday is a first step toward one day growing customized new ears for children born with malformed ones, or people who lose one to accident or disease.
This first-step work crafted a human-shaped ear that grew with cartilage from a cow, easier to obtain than human cartilage, especially the uniquely flexible kind that makes up ears. Study co-author Dr Jason Spector of Weill Cornell Medical Center is working on the next step - how to cultivate enough of a child's remaining ear cartilage in the lab to grow an entirely new ear that could be implanted in the right spot.

As a specialist in plastic surgery he hopes this technology could be used for facial reconstruction of burn patient. via 3ders.org.
