Scientists have designed a bionic ear that can hear better than human ears. And get this: It was created using a 3D printer! http://on.mash.to/Z4rDZ7
Wow!! Did you see the backslash on that machine!
I wouldn’t want to have that ear!
Yep, a completely cobbled together bioprinter. They should go talk to the folks on reprap before they start selling those body parts. 
Rotfl! I just printed a ton of arms and a couple legs from my printer.
