Material of Expansion Cards

I etched mine last year and I think I just used the normal etching settings and plunger?

Color Coded Expansion Cards

So my school got a laser engraver/ cutter this year. I had never used it before but it is really easy. You get your image in inkscape, you want it to be black and white and then make it into a bitmap. Then you print it using the laser and just put it on image mode. I used the plunger focus method. This was on an epilog.
