Can 3D Printers Reshape the World?

What if you needed a new toothbrush and all you had to do was hit print? What if doctors could print out transplantable organs and pastry chefs turned to a printer, not a kitchen, for their next creation? Ira Flatow and a panel of guests discuss 3D printing technology, how far it’s come, and what a 3D-printed-future could look like.

Think you know the capabilities and limits of current 3D printing technology? Take our quiz.

In the video below, Dr. Lawrence Bonassar, Associate Professor of Biomedical Engineering at Cornell University, describes a cutting-edge process to create body parts such as ears using a 3D printer and “ink” composed of living cells.
