I did some more research on using liquid powder coat with a laser. There are some people experimenting with this plus many big companies. I found a company that is powder coating MDS and using a laser to give it a wood grain effect for doors and windows. Another website said you need to use very low power to just get the powder coat to flow and attach to the substrate. Then you can remove the excess and cure the piece in an oven or with a heat gun. Also there is a You Tube video of a guy that powder coats wheels the conventional way, but he also powder coats a plastic center plug to match using a heat gun to cure it. So I am excited thinking the process could work. Use the liquid powder coat on your part, Let it dry. Put it in your laser to add some text or graphics. Remove the excess powder coat. Then cure the part in a 400 deg oven or with a heat gun. You should have great looking powder coat graphics in any color. The website said you need very low power to just get the powder coat to flow and you might have to defocus the laser to spread the heat and not destroy the part.
