3D printing cartilage to take rhinoplasty by the nose

FIRST STEP: They may look like Venetian masks, but they represent the steps towards making 3D printed, living cartilage.

In just 16 minutes, it's possible to print out living cartilage to give you a new nose, thanks to scientists at the Federal Polytechnic University in Zurich (ETH Zürich). 

They call the process bioprinting, because they use actual cellular materials – in this case living cartilage cells, mixed with biopolymers.
