I believe that Alstom Power in the UK did this a few years back but the
person whi did it (Chris Gray I think) left the company shortly after. I
believe that it worked OK but I am not sure that they looked through SL.
However with todays materials I would expect it would be likley to work. At
100 deg C may SL materials are above the Tg and can lose some rigidity but
if the part isn't subject to mechanical loads (including its own weight)
then it may be OK.

Dear All,

Has anyone ever done heat transfer experiments with liquid crystals
sprayed on a stereolithographic model? If you need to look through
several sections of stereolithography, can you still see the liquid
crystals changing color? Can you heat a model to 100C (212F) without it
melting or releasing vapors?

I'll appreciate any information that you can shed, even if it's slightly
