CRP from Italy market the Windform product range of powders for use in
all systems. There was some dialogue between EOS and CRP over patents
that is still available on their respective websites. and
In the UK, Amber Composites Ltd has become an official supplier of the
Windform product range, and I know of one bureau using Windform XT (
carbon filled )

EOS sells directly to customers in the US and other parts of the world.
I think part of the settlement with EOS was to allow sales of powder in
the US. I believe some customers may be using materials other than
those offered by 3D or EOS. . . but the legality of that has to do with
patent claims. . . I'm sure if EOS or 3D felt that someone was
infringing on a patent, they'd get a letter.

Do they?
        Hi Folks:
        Does anybody know the legal situation surrounding whether it's
possible for 3D selective laser sintering users to purchase materials
from parties other than 3D?
        Someone asked me about the lawsuit between 3D and AMES / EOS
GmbH a few years back and I really couldn't figure out what the final
disposition was. I believe that the matter might be covered in the
cross-licensing agreements that resulted from 3D and EOS burying the
hatchet. Also, I would assume that it would have always been possible
to buy materials that didn't violate 3D/DTM's patents, assuming they
worked and were available.
        Are people buying SLS materials from sources other than 3D these
