Simon Wardley posts a 24 minute video of his talk from the September 2006 EuroOscon, in which he speculates about the affects of 3D printing technology on the future of manufacturing - including the revolutionary concept of a kind of "hardware compiler".

This simultaneously interesting and amusing presentation covers the historical view of how such technologies evolve. For example he compares fabbing to the evolution of the photo printing industry and thus predicts 3D printing's path from initial innovation to future ubiquitous utility service. There are also excellent overviews of various 3D printing techniques. And of course, ducks.
