I got my vinyl dye at an automotive paint supply store.
They can custom match any color.
It was $10.00 for a spray can of standard color.
I also used it to color some molded plastic parts.
I cant scrape the color off.
I found it worked great on FDM ABS parts.

I was told that DTM did in fact supply coloured powders to selected
customers who wanted to make parts in standard (e.g. computer brown/grey)
colours. This didn't work very well for obvious, marketing reasons. This was
one of the reasons we looked at colouring in-situ.
Certainly there would have been differences in the laser/material
interaction for different colours/additives. We noted changes in thermal
conductivity for example, although it is probably not so much due to the
colour as some of the other material properties (molecule size, lattice
structure, etc.). For homogeneous mixtures this would be quite easy to
characterise and program. Where you are making functional gradients (i.e.
changing the mixture), this would be more difficult.

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
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.
