UV cured resin
As a next step, we removed the DLP's mercury arc lamp and drove it positioned just a few cm directly over the resin.
We then removed one of the filters from the light path and the color wheel. The projector wouldn't turn on with the color wheel removed, so we have it carefully mounted outside of the projector during the next test.
We probed various parts of the light path with a blob of resin to see where it would cure into a solid mass. It appears that the final optic stage before the DLP filters too much of the UV at the necessary wavelengths for this resin.
So we didn't have total success. Maybe the stamp resin is too insensitive -- it is typically exposed via a very strong UV source through a contact print. We'll order some of the Bucktown Polymers "fast curing" goo for next week's testing and also start to work on the Z-stage to draw the printed object from the bath once we have the formulation and exposure times experimentally determined.
