3D Printing Creates Artificial Ear

With 3D printing, it seems the things you can make are limited only by your imagination. The latest innovation: a 3D-printed artificial ear.

The ear, which looks and functions like a normal human ear, was created by squirting living cells into an injection mold. Over the course of three months, each ear grew cartilage in the shape of its mold. These ersatz ears could replace the ears of children with congenital deformities, researchers report online today (Feb. 20) in the journal PLOS ON
