Questions on DuraForm GF and other options
Mike -(and everyone else who's interested) -

We often build water-tight parts with Duraform GF infiltrated with Imprex
Superseal(TM). This stuff is water-thin, and we immerse the part(s) in a tub
of the superseal in a vacuum chamber. We take them out when the bubbles stop
coming out of the part, and cure them in an oven at 150F for about an hour
(depending on part size and thickness). This process has yielded parts up to
an inch thick being completely infiltrated.

Good luck, and let me know if you have any other questions.

  Subject: Questions on DuraForm GF and other options

          I was wondering if someone could help me with my question. I'm
looking at making a testable prototype from an SLS with DuraForm GF. The
questions is regarding the finishing process. One options is a vacuum
impregnating the part with a Methacrylate resin the other is treatment of
Cyanocrylate. What is the difference and effect of these two process? I will
be running the part in water and machining it down in between my tests.

          Also, are there any better materials (e.g.. strong and more
durable) than the DuraForm GF that can be tested in water that I should be
looking into? (not including steel RP, the build area is not large enough)
The Stratasys Polycarbonate and Polyphenylsulfone also looked like an
option, but I still need to do more research on this.

  Your comments and suggestions will be greatly appreciated.

  Thanks in advance,
