Ashlee Vance has an update from the front lines of a "manufacturing revolution." He writes about how the widespread availability of 3D printers is changing the equation for entrepreneurs:
These days [3D printing] is giving rise to a string of never-before-possible businesses that are selling iPhone cases, lamps, doorknobs, jewelry, handbags, perfume bottles, clothing and architectural models. And while some wonder how successfully the technology will make the transition from manufacturing applications to producing consumer goods, its use is exploding.
