People think 3D printing is going to change the world. They imagine ways that it might transform our society, economy, and culture. In this episode I look at why 3D printing is so compelling-- why everyone is so interested in it right now. I talk about where 3D printing came from and how it's changing, examine the structure of how people popularly imagine 3D printing, and look at the Utopian hopes that people attach to the technology.

Chris Anderson has a nice history of 3D printing and some interesting thinking about potential changes in manufacturing and entrepreneurship. Anderson is also the source for the analogy with the development of computers. Chris Anderson, Makers : The New Industrial Revolution. London: Random House Business Books, 2012.
