摘要：Based on the results of a 2012 survey on people doing 3D printing, we present results on the demographics and self-identification of the community, as well as describing participants' printing activity. Combining results from the survey with insights from research literature, we analyse emerging patterns and practices of 3D printing as a subdivision of a more general trend of physical peer production, and, even, of a revolution in manufacturing, as predicted by several theorists.
