This document explores the potential for social innovation in manufacturing through "maker manufacturing". It identifies three dimensions of social innovation in manufacturing: 1) Democratization of making through open tools and sharing of knowledge; 2) Supply chains for good through full transparency; and 3) Corporate citizenship by making social/environmental impact part of business strategy and decision-making. The document argues that maker manufacturing could contribute to the European Commission's agenda of jobs, growth, fairness and democratic change, but risks need to be managed. It calls for political support to realize the potential of this emerging field.
