Making it real with 3D printing

The thrill of 3D printing is that is bridges the virtual and the actual. Based on manufacturing technologies developed decades ago, the 3D printing process begins with carefully wrought 3D design files and ends with the robotic arm of a 3D printer flying around to fabricate physical objects of plastic or metal. It's the darling of hacker and steampunk communities and the hope of many who'd love to see a boom in small-scale manufacturing. J.K.
