Some months back I gave the closing keynote at QuahogCon. It was an overview of the digital manufacture techniques available today focusing on 3d printing. I gave detailed information on how to interface with them, what properties different techniques impart, and how to generate geometry.
You can find an audio recording of the presentation here. You can also download my resources (containing links to artists, 3d printing companies, software tools, and awesome projects) here. You can also find my presentation’s visuals on Prezi.
