What is the best way to color the white SLS parts? I heard of dye and paint. Paint I am not really interested in as these parts are going into a manufacturing facility and the last thing I need is for paint to chip off, have toxic chemicals in it, etc.
Plus the parts often get auto-claved at 250 degrees for 60 minutes, I don't want paint to 'bubble'.
I was considering food dye for the coloring the parts.. but was wondering what the best method to do this is? and will the dye 'bleed out' if you put the parts into a say a dishwasher afterwards?
