A coming revolution in 3D printing, with average consumers able to copy and create new three-dimensional objects at home, may lead to attempts by patent holders to expand their legal protections, a new paper says.

Patent holders may see 3D printers as threats, and they may try to sue makers of the printers or the distributors of CAD (computer-aided design) blueprints, said the paper, from digital rights group Public Knowledge.

"The purpose of this report is to alert the public and policymakers to the issues raised by a technology that is still in its infancy, much as personal computers were in the early 1970s," the paper said. "Existing industries could demand radical reformation of intellectual property law, or the creation of entirely new types of intellectual property, when confronted with widespread 3D printing."
