Rapid prototyping of PEEK

I have a problem in manufacturing a part out of PEEK or any other polymer
that can withstand ammonia and mineral oil up to 70 deg C and still have
reasonable mechanical properties. I have made some test cutting unfilled
PEEK and GF-Nylon with laser without achieving a useful result. We have also
tried with a part made from a casting in a PU mould but that material,
(ABS?) turned from a brittle quite strong plastic into something more like a
hard rubber. It did also change it's dimensions.

Any help is very appreciated,
