More fun with lasers and powder coating.
This time I covered the aluminum with Kapton tape then lasered the letter outline to make a stencil. Applied the powder coat, cured it and removed the tape.
Not perfect as I was unsure of speed and power settings to cut through the tape so I ran two passes. One would have done it.
But definitely a very viable method.

Also wanted to see if the powder could be melted with my heat gun.
Ran two passes on maple at 500mm/min and 80% power which gave me about an 1/8 doc.
Filled it with powder and melted it with the heat gun on low volume, max heat. Sanded off the excess.
Worked great.
