blackbearnh writes "An article over on O'Reilly Radar makes the argument that, just as inexpensive or free software development environments have led to a cornucopia of amazing Web and mobile applications, the plummeting cost of 3D fabrication equipment could enable myriad new physical inventions. The article was prompted by a new Kickstarter project, which if funded will attempt to produce a DIY CNC milling system for under $400. Quoting: 'We're already seeing the cool things that people have started doing with 3D fab at the higher-entry-level cost. Many of them are ending up on Kickstarter themselves, such as an iPhone 4 camera mount that was first prototyped using a 3D printer. Now I'm dying to see what we'll get when anyone can create the ideas stuck in their heads.'"
