Non-Conventional Copyright

Do New and Atypical Works Deserve Protection?

Edited by Enrico Bonadio and Nicola Lucchi

This book draws a picture of possible new spaces for copyright. It expands on whether modern copyright law should be more flexible as to whether new or unconventional forms of expression - including graffiti, tattoos, land art, conceptual art and bio art, engineered DNA, sport movements, jokes, magic tricks, dj-sets, 3D printing, works generated by artificial intelligence, perfume making, typefaces, illegal and immoral works - deserve protection. The contributors offer authoritative, coherent and well-argued essays focusing on whether copyright can subsist in these unconventional subject matters.

Chapter 16: Subsistence of copyright over CAD files in 3D printing: the Canadian, the U.S. and European outlook

Teshager Dagne


Three-dimensional (3D) printing is a manufacturing method in which materials, such as plastic or metal, are deposited on to one another in thin layers to produce a three-dimensional object. The process of 3D printing involves the preparation of a computer-assisted design (CAD) file, which may be derived from pictures or drawings, scanned from goods using a 3D scanner, or downloaded from websites. Such a file can easily be distributed, copied, modified, and then ‘printed’ by a printer device. As a core element of the 3D printing phenomenon, a number of questions arise over the CAD file, including the subsistence of copyright over CAD files to be used in 3D printing, i.e. whether copyright exists and applies to the work. This chapter discusses the subsistence of copyright over CAD in 3D printing files under Canadian, United States and European Union copyright laws.
