Via Joseph Flaherty, who writes:

“While I was at MakerFaire it was impressive to see how much energy there was around Open Source 3D printing. The MakerBot was the belle of the ball, but the Fab@Home, RepRap, and other Open Source projects were well represented as well. It is exciting to see is the improving quality of the models that are being created. With more designers all design problems are shallow. Complex transformers, interesting puzzles, and multi-material builds show how much opportunity there is even in affordable platforms.”
