FW: prototype in polypropylene?

Some clarification of my posting (see below). We are interested in
purchasing a RP system that can produce parts in PP. I appreciate the offers
from service bureaus for their services but I need to be able to produce in
house, real PP parts for fit / function testing as well as welding onto our
existing parts to simulate revisions. It seems like there isn't anything
currently available that can do this. The closest may be an SLA made with a
flexible resin (9100?). The reason we shy away from getting an SLA machine
of our own is the materials handling of the resins, costs associated with
the machine, and technical expertise needed. We went with the ZCorp machine
for it's ease of use, benign materials, and costs are relatively low. The
process works very well as a rough modeler - we've turned out 90+ part some
weeks. We need another process to compliment what we now have. If anybody
has any thoughts, please email me (rather then calling).
