    as far as engraving and color filling better read this, but in short :

    "As a rule of thumb, with characters up to 1/4" high, engrave to a depth of .010" -.012". On larger characters, it is advisable to go .015" - .020" deep depending on theline width and filling technique used."

    Laser works best for engraving aluminium :-)


  6. What size of laser do you need?

    Mine is 10w, 1023nm, galvo. You can do it with a 6w blue fibre laser on an xy gantry home made. Size is not really the issue, beam quality is more important..
