Past tests with glass filled nylon (before Duraform) showed material properties in the Z direction to be about 75% of X and Y directions. I believe DTM's material properties are based on XY orientation. Now we generally only test for Z oriented parts and design around those lesser properties.
It's also interesting to note that we saw no significant differences due to build orientation of sla parts.
