The Next Disruptors at Business 2.0: "Desktop Factory is developing a 3-D printer for the masses. It literally prints out three-dimensional objects made from a gray plastic powder. Most rapid-prototyping machines cost $50,000 and up. When Desktop starts selling its machines later this year, they will cost $5,000. And they eventually want to get them down to $1,000."
To quote a recent NY Times piece: "The legal landscape, though, may not be ready for the Napsterization of three-dimensional things."
