Outstanding use of 3D printer

This is a perfect demonstration of what the new generation of printers can achieve.  Just imagine taking one of these machines to a third world country and printing off tools, bicycles, furniture, almost anything needed. As prices come down and the limits are refined, tested, and expanded 3-dimensional printers are going to change the way the world does business, decentralizing the manufacturing industry and shifting towards a data economy rather than a commodities economy.
