Exception in Copyright Office rule could threaten ability to unlock 3D printers

Michael Weinberg, Shapeways’ IP and General Council, is calling on the 3D printing community to sign a petition he has drafted to amend a rule renewed by the US Patent and Trademark Office. The rule, which is meant to allow people to unlock or “jailbreak” a 3D printer to use nonproprietary filament, currently contains an exemption which could effectively override the rule.
