Association of Professional Model Makers (APMM) 2010 Conference Keynote Speech.
Given March 27, 2010 at Cambridge, MA, Professor Neil Gershenfeld, Director of the Center for Bits and Atoms at MIT discusses proliferation of the FABLAB concept and the process of disseminating manufacturing capability to the population at large. The audio is a bit difficult, but it's a very good introduction to the subject. The speech is given in four sections due to the 10 minute limitation on youtube. Use these links or search youtube using the words Gershenfeld and APMM to find these four videos.

Homemade High Resolution 3D Printer - DIY This blog from Junior Veloso of Brazil describes how he built a photopolymer-based system using exposure from a used deformable mirror device (DMD) projector. The results appear to be fairly close to commercial versions of the machinery available from Envisiontec GmbH and others, while involving only an expenditure of US$2,800. Be forewarned, however, the method is covered by many US and other patents so this project would be illegal in the US.
