Artificial Ear built from Sheep Cells
August 2, 2013

An artificial ear that looks and works just like an outer human ear has been built by scientists using a 3D printer and cartilage from sheep. The organ was designed by plastic surgeons to make it look as lifelike as possible. 
Scientists are now preparing the ear for clinical trials in the hope they can be used in transplant operations. As the technology is customizable, the scientists claim they could eventually use the process to produce realistic looking ears for individual patients on a ‘rapid timescale.’
