These two pieces appeared on BoingBoing this week:
1. First this piece, about a synthesizer manufacturer who, finding it cost-ineffective to produce and ship replacement knobs/buttons/sliders, has opted to release the 3D models for free, to allow people to either 3D print them themselves, order them from places like Shapeways.
2. Secondly this piece, which needs the BoingBoing parargaph copied to make a point:
Defense Distributed is a collective that raised $20,000 in BitCoins to lease a 3D printer and develop and prototype a 3D printed pistol. Stratasys, the manufacturer of the printer, seized it from the home of Defense Distributed's Cody Wilson, after a heated email exchange
Re-read that. A real story involving crowdfunding, crowdsourcing, a digital alternative currency, 3D printing, and the war on general purpose computing, all in one tidy paragraph. Welcome to the future.
