DPT had our Connex500 installed in early January. The installation took
approx 3 days and our experience was very similar to Tom's.
Our customers have been very pleased with the quality of parts from the
machine and are taking advantage of the dual material capability;
specifically to prototype substrates and over molds in a single build. We
have run all of the materials offered for the Connex series and are gaining
feedback from our customers as our parts are being used.
>From our experience the parts have slightly less impact strength than
typical SLA materials and much less impact strength than DMX-SL 100.
Thanks

Bob,
The tear strengths are unfortunately what they are for the Tango
materials, but from the customers I run these rubber materials for (some of
them who also own SLA & SLS), they all state the Objet Tango elastomers are
the best elastomers in Rapid Prototyping today. In fact, the Tango
elastomers equate to around 55% of my total jobs. I did have some tear
strength issues once and I replaced my UV lamps and it got rid of the
problem. Head weights are also critical. Shake your Tango cartridges up
gently for about 3 minutes if they have been sitting for days at a time
before running it. I've found "settling" occurs in the Tango cartridges and
it acts like paint that sits for awhile.
