Rapid Prototyping or RP describes a number of technologies that includes 3D printing. Turning an X-Y process into the 3rd dimension. The technologies involved keep getting better in resolution and larger size components that can be made. Fortunately, other advances are making the technology more affordable. Advances in the open source community for microcontrollers like Arduino are allowing designers to easily and affordably copy these big brother technologies in a desk top version. Here at the Cyber Wigwam we added the Makerbot 3D printer to exhibit the capability of 3D printing. Soon, tepees and arrowheads in 3D will be adorning the cyber Wigwam. At the root of the Makerbot is the Arduino micorcontroller technology. Massimo Banzi presents an excellent overview of open source ideals and how it impacts creativitiy below.
