The mainstream media is producing introductory pieces on 3D printing with a bit more frequency in recent weeks, including a piece on CNNMoney. They talk of how innovative folks are leveraging the tech to make money in new ways. One of their examples is a Shapeways creator, who filled a gap in Lego's product line using Shapeway's print service.
However, we think the article is too optimistic when they say "3-D printers come of age". Current 3D print tech is still beyond the usability limits of most people, even when using print services like Shapeways, as most people don't understand the concept.
Nevertheless, any mainstream media coverage is good coverage, and it'll gently increase public awareness.
