The UK government has extended copyright for designs from 25 years to the life of designer plus 70 years. This follows a decision in the European Union, where member states are required to adhere to such an order. This change means people will be prohibited from using 3D printing and other technologies to manufacture such objects for a full century.
Furniture was previously protected by a design patent and not by copyright. This change will result in big changes for 3D printing: when something was under patent people were free to make copies of it for their own use with their own tools and materials under copyright this is illegal.
