Last March we pointed to the RepRap project -- an attempt by Dr. Adrian Bowyer of the University of Bath's Centre for Biomimetic and Natural Technology to design and build a Free/Open Source fabber. In the subsequent few months, Dr. Bowyer and his team have made substantial progress, including adopting a "Meccano" structure for the test unit similar to the Glue Gun Fabricator devised by Vik Olliver; a report by Vik Olliver detailing how to make one for yourself (PDF) can be found at the RepRap website, along with all of the current plans and design reports.
