Very intriguing to see that you'll be competing on the price point of the Makerbot and other FFF printers rather than with the Form 1. Though with DLP rather than laser scan, I can see it being realistic.

I have to wonder what made you guys choose a 7"x4"x9" build envelope? It seems a little awkward. Also why would vertical speed change with x-y resolution, a layer from the DLP projector should take the same amount of time to cure no matter what the image resolution is.
