Very interesting article here at NY Times about 3D printing and copyright.
Downloading — quite often stealing, in the eyes of the law — music, movies, books and photos is easier than bobbing for apples in a bucket without water. It has kept legions of lawyers employed fighting copyright violations without a whole lot to show for their efforts in the past decade.

It won’t be long before people have a 3-D printer sitting at home alongside its old inkjet counterpart. These 3-D printers, some already costing less than a computer did in 1999, can print objects by spraying layers of plastic, metal or ceramics into shapes. People can download plans for an object, hit print, and a few minutes later have it in their hands. via NY Times
