Rapid Prototyping Content:
SLA machines run fairly quickly. I believe the units we used had a 1mm thickness interval, and each layer was done in a quick flash. However, I seem to recall that the cleanup of the part(s) was the most time consuming. The nylon is not very stable (due to temperature/light) so we always painted our models. That was after all the hand-sanding and detailing. Our turn-around time was a couple days.

Swerve Content:
Looks like a nice package. Is there only the single rotational bearing through the midline of the unit, or is it supported near the top as well? Also, are you making the swerve sprocket yourself, or is that an off the shelf part? Do you have an estimate cost for a full-up module? (I'd love to hear what it cost other teams to do a similar design.) I hope to see it in 2007!
