From working guns to a dead king's face, we've seen some pretty weird things created with a 3-D printer. It may seem like science fiction, but it seems almost certain that 3-D printing will play a significant role in many industries of the future. And there's good reason to be optimistic.
3-D printing could greatly reduce the amount of materials needed in manufacturing everyday items, and it would eliminate the need for a complicated, resource-intensive supply chain. (Why ship parts across the world when you can print them at your desk or local shop?)
3-D printing may also make recycling easier and more "hands on" - with one concept allowing homeowners to recycle their plastic bottles into useful household items. But how does a 3-D printer actually work? As someone who has always struggled with the intricacies of science and engineering, I thought it was about time I found out.
