"Open source software has been a key player in all kinds of disruptive technologies — from the Web to big data. Now the nascent and growing open source hardware movement is helping to power its own disruptive revolution. ... As 3D printing, powered by Arduino and other open source technologies, becomes more prevalent, economies of scale become much less of a problem. A 3D printer can print a few devices — or thousands — without significant retooling, pushing upfront costs to near-zero. This is what The Economist calls the 'Third Industrial Revolution,' where devices and things can be made in smaller, cleaner factories with far less overhead and — significantly — less labor."
