I assume you have coloured the parts after they have been built. Ian Gibson
at Hong Kong University has tried adding colour and graphite to SLS material
prior to sintering. Has anyone tried using coloured powders for SLS and does
it affect the ability of the powder to absorb the laser or any other
processing parameters?

  Is anybody using vinyl dyes for coloring SLA, SLS or other prototype

  I recently used this to color some plastic parts and it worked great.

  It is a penatrant, not a coating, so it did not fill in the small text on
the piece I colored.

  It also seems to be quite durable.

  Just curious.
