3D Printing is now changing the way we manufacture many objects in amazing ways, from tools, toys, and jewelry, to food, and even body parts! It's a technology revolution happening in new kinds of factories, and even in homes, around the world. But how does it work exactly, and why has the economist, Jeremy Rifkin, called it an important key to the Third Industrial Revolution? This talk explains the basics of 3D printing technology, and what you need to know to begin designing and printing your own creations, with or without your own 3D printer.
