Hello List,
I posted an inquiry several weeks ago and wanted to let you know the results.
The inquiry was a series of questions on Rapid Epoxy Tooling
I received 3 responses. 1 Via telecon. We discussed the different
materials used and average tool life.
2 were via email. One of which was an interest in the results of this inquiry.

were doing epoxy or composite tooling.
