RDWorks Learning Lab 236 Powder Coating with your Laser

I have been sent video links of people using plastic powder coating materials to coloiur fill deep cut wood engravings. Hmmm . Their results look OK from a distance and yes the idea is perfectly logical. Add heat to plastic and it melts (provided you are not too enthusiastic). Having been a user of the powder coating process for many years, I understand how it is designed to work.....and wood is not on that list of suitable materials. This is an investigation to see if the process is really viable and what parameters, if any, should we be using. Could it be extended to other materials?
