I'm a bit late to the thread here, but we had some unsatisfactory
experiences with AAE when having them fabricate a set of 2-D CCP
nozzle test samples for a research program.
The first set came in as a total negative of the provided Solidworks
drawing (filled where there should be space, and milled out where the
material should be), and a portion of the samples had an internal
kink in the ply angle (that we didn't discover until post-test
sectioning) making it more difficult to analyze the data.
We had heard good things about them and their products from some of
the larger primes/gov't, so our experience was quite disappointing --
perhaps they're not focused on relatively small custom orders. Caveat emptor.
