Luis Alvarez Talks With Rebecca Costa about 3D Printing

There are technological innovations that can be cold and boring, and we’ve seen lots of those. But then there are some really freakin’ cool technologies out there that make you say what the? ... And I recently learned about one of these technologies. You watched “Star Trek” back in the day, right? I know, we age ourselves. But since then, we’ve seen a lot of the “Star Trek” pretend gadgets turned into real devices that we use today. The communicator became the mobile phone. The tri-corder became the first tablet. But the device that most impressed me – aside from the transporter, by the way -- was the replicator. If you recall, that was that magical gizmo that you were able to use to get anything you needed on demand, even food.
