In her TED talk, Lisa Harouni delivers a primer on 3D printing | Video on TED.com. Lisa is co-founder of Digital Forming.

Also referred to as additive manufacturing, 3D printing empowers anyone with the ability to manufacturing single or multiple products of all sizes and literally all shapes. There are production capabilities equal to the design details of a human lung that only 3D printing achieves.

In the process, very thin layers of various materials follow detailed 3D designs to create seamless objects.
