I had sent out a note a few weeks back asking if anyone had been having
any problems with running SLS glass duraform. We had been experiencing
some very strange surface problems on our parts and found out that there
were several others experiencing the same or similar problems at that
time. DTM provided us with some short term material corrections but
recently we have started to experience the same sort of problems again,
but not to the magnitude as seen before. Is anyone out there finding
that the duraform (glass or regular) is not anywhere near as recyclable
as we were sold on it be? The nearly 50% material price increase over
the old nylon materials is very difficult to stomach when we are finding
that the old nylon products are more recyclable than the new duraform.

Is anyone experiencing the same sort of build problems? If so please let
me know what you've been told is the problem and if there have been any
solutions. I'm interested in finding out the root problem and corrective
