Advances are rapidly being made in what has been variously labeled "personal-", "desktop-" or "digital fabrication". The most often discussed example is low-cost, easy-to-use 3D printers that allow ordinary users to "print" objects in their homes. 3D printers and other technologies of the same kind are believed to create radical new possibilities for inducing new consumer habits and transforming existing production methods. According to a row of policy institutes, digital fabrication will become a motor for economic growth and social innovation (MAKE, 2011; IDA paper, 2012). Echoing the same promises, the business press has announced the advent of personal manufacturing and a third industrial revolution (Economist, 2011; 2012). Some policy reports even claim that digital fabrication could restore the competitiveness of manufacturing in developed nations and reverse the trend of outsourcing (Lipson & Kurman, 2012). The positive economic outcomes expected from this technology are linked to the hope that digital fabrication tools will open up innovation processes to heterogeneous actors, such as grassroots groups, start-up firms, and users (Chesbrough, 2003; Lipson & Kurman, 2012).
