It seems you may know then better than me. My impressions were as you said, just trying the material with my hands. I have never done extensive tests. One thing is clear though, that of course the part should be beefy, compared to normal one. I have more experience with stereo lithographed parts and most of all PolyJet-ed.

As i said its an art. At least when you have all good set up, you can start to reliably test and play until you have it figured. Having unreliable setup will further complicate or even make perfection impossible.
