For those who are still unfamiliar with the concept, in 3D printing (or additive manufacturing) a digital file of a computer-aided design is sent to a "printer" that creates an object by depositing successive layers of materials a few microns in thickness. The "ink" from which items are fabricated can be various materials such as molten plastic and composites.

Over the last several years 3D printing hardware costs have decreased significantly and the range of 3D printed products has expanded. Yet there are a number of important supply chain-related questions about the technology and its application that still need to be answered.
