The maker movement is placing small-scale manufacturing development on mayoral agendas across the United States and promises to reinvigorate production economies in central cities. To make effective policy, planners need more knowledge about the entrepreneurs at the center of this phenomenon. Here we present a qualitative

investigation of urban maker economies. We draw on semistructured interviews with firms and supportive organizations inChicago (IL), New York City (NY), and Portland (OR). We find that makers draw on

ecosystems comprising mainly for-profit firms. The public and nonprofit sectors are important in areas where markets do not provide the resources that fledgling makers require. We find 3 distinct types of maker enterprise: micromakers, global innovators, and emerging place-based manufacturers. Each makes a different contribution to local economic development.
