3D Printers as a Design Tool

We got our first 3D printer a few months ago and started to mess around with it and print anything we could think of just for fun. We knew that in theory, 3D printers are a great tool, but we hadn't yet figured out how to make it work with our company.

A couple weeks later we were putting together an order for some parts to get externally machined, and realized that we can 3D print this $100 machined part for about $0.07.
