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.

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.
