Digital Encryption Patent Could Bring Copy Protection to 3D Printing

Nathan Myhrvold, the former Microsoft CTO who currently runs Intellectual Ventures, has been issued a patent for a system that could prevent people from printing objects via 3D printers using designs for which they have not paid.
“The patent, issued [October 9] by the U.S. Patent & Trademark Office, is titled ‘Manufacturing control system’ and describes methods for managing ‘object production rights,'” reports Technology Review.
“The patent basically covers the idea of digital rights management, or DRM, for 3D printers,” explains the article. “As with e-books that won’t open unless you pay Barnes & Noble and use its Nook reader, with Myhrvold’s technology your printer wouldn’t print unless you’ve paid up.”
However, there is a caveat to consider since manufacturers are not required to use DRM.
According to ETCentric staffer Phil Lelyveld: “The patent appears to be incredibly broad, but as the article says it only applies to 3D printers that implement DRM technology.”
The patent goes beyond 3D printing to include additive manufacturing. “It also covers using digital files in extrusion, ejection, stamping, die casting, printing, painting, and tattooing and with materials that include ‘skin, textiles, edible substances, paper, and silicon printing,'” notes the article.
