RE: Question re: Testing RP SLA Parts

David, as I write our mech sys lab is testing parts for us... 5180,
6110, protoform and duraform. These tests are not precision as we're
just looking for rough material properties but we are testing various
orientations. I can certainly inform you of the results. What we are
not doing is testing the materials for strength as a function of time or
temp nor our we checking stability over time. This is other data I
would appreciate feedback on if you get it. Keep in touch,
