We did some work in coating stereolithography parts with chrome by use of
PVD technologies. The coating is very thin (some micrometers) but has a
good adheresion strength. But postprocessing is necessary because the
parts tend to outgasing what will effect the coating. The postprocessing
depends on the exact material.

We can do some examinations, but we are no service bureau.

Far out in the uncharted backwaters of the unfashionable end of the
Western Spiral arm of the Galaxy lies a small unregarded yellow sun.
Orbiting this at a distance of roughly ninety-eight million miles is an
utterly insignificant little blue-green planet whose ape-descended life
forms are so amazingly primitive that they still think digital watches
are a pretty neat idea ...
