3D Printing - Additive Manufacturing

A few days ago, I watched an amazing youtube video that demonstrated 3D Printing. The 3D printing blog  3D Printing an Additive Manufacturing discusses this new technology that will revolutionize manufacturing as we know it.  3 D Printers are available that can create three dimensional products out a variety of materials.  The cost is dropping dramatically, and some 3D printers are available for under $15000.
