This Ear Was Made With A 3D Printer And It Hears Better Than Your Ears

WATCH: This Bionic Ear Was Made On A 3D Printer

While some people are using 3D printers to make guns, scientists at Princeton University are using them to create working human ears. By combining "bio-printed organic materials" and electronics, scientists have created an ear that can hear things that regular human ears can't.

"Our work suggests a new approach — to build and grow the biology up with the electronics synergistically and in a 3-D interwoven format,” lead researcher Michael McAlpine told The Daily Princetonian. The ear is the first attempt to blend human tissue and electronics, and is not yet ready for use. When it's ready, the bionic ear would work more like a hearing aid than anything else.
