David ,

Thanks for all your info on the Connex. We have two Objet machines and
considering adding the Connex or getting another 500. I have a couple of
questions about the materials and maybe you or one of the other Connex
owners can help.
  Has anyone tried pattern finish and painting the Multi Material parts and
wanted to know how well they accept the sanding and paint. We have noticed
that there is a considerable time difference finishing parts built in high
speed vs. high quality.
  Also with the mixing of Tango with the Vero and Fullcure if the tear
strength has increase with these mixed parts. The tech data sheet can say
one thing but actually handling the parts and using them are another thing.
   As far a the US accepting 3D printing. We have found that more customer
are asking directly for Objet parts. Slowly but surely we believe that it
will become as common as SLA, SLS, FDM etc. in the US soon.

Have a Great Day,
