Re: Color SLS Prototypes?

On dying the part, it needs to be less dense than normal. If you run a
duraform part fully dense, the dye will not penetrate and in the end it will
give you a "dirty" look because the color will not be complete. Of course,
you can always use paint.

> David, there are several possibilities for colored SLS prototypes. If the
parts were flexible, then they were quite likely the DuPont SOMOS for the
SLS process that I have seen in many different colors. I don't run the
material, but I believe it is infiltrated with a urethane after processing
that can be made in different colors.
> Another way is to use RIT dye on the Duraform parts. Have not done a lot
of this but we have done it successfully. The dyes come in every color
imaginable. Seems to work best on Duraform and less well on Duraform GF.
> Good luck,
