For several months I have been seeking to verify that Perfactory models
can indeed be directly investment cast. So far I have not had much luck.

If you are seriously considering doing this, then I would strongly
suggest that you use the Ceramic Shell process instead of conventional
jewelry/dental type investment materials. It is capable of handling
much higher temperatures and would help ensure a successful outcome.
