I work in the field of colorants, color measurement, and color control. Do you have any interest in discussing colorants for use with your resin to be able to produce parts in the desired shade? Obviously, the colorants (dyes or pigment dispersions) would have to be benign to the laser curing of the resin.
Please let me know if you are interested in a discussion. (Painting is nice . . . but it’s only skin deep.)
There are excellent spectrophotometers which can measure small areas; also, the color of the liquid resin could also be measured and adjusted, if necessary.
