3D printing and the intellectual property system

Three-dimensional (3D) printing – or “additive manufacturing” – technologies differ from traditional molding and casting manufacturing processes in that they build 3D objects by successively creating layers of material on top of each other. Rooted in manufacturing research of the 1980s, 3D printing has evolved into a broad set of technologies that could fundamentally alter production processes in a wide set of technology areas. This report investigates, from the perspective of an intellectual property scholar, how 3D printing technology has developed over the last few decades, how intellectual property rights have shaped this breakthrough innovation and how 3D printing technologies could challenge the intellectual property rights system in the future. As in other areas of innovation policy, the role of the intellectual property system in fostering innovation in 3D printing technologies is a complex one. It played a beneficial role in some instances (sometimes intended and sometimes unintended), and it may have played a neutral or detrimental role in other instances. Studying the progress of 3D printing technologies thereby also informs us about the intricate relationship between intellectual property and innovation.
