Laser Cutter/Metal
From London Hackspace Wiki
On 2013-08-07 I etched the back of my macbook air using the Engraving setting.
Speed was 200, Power was 80.
The effect looks good in bright light (when it looks black) The 'whiteness' of the etching is inconsistent, looking dirty/smokey in areas where it was denser. I'm guessing maybe some of the smoke? got annodized into the metal? Anyway it was on the back and just a test.
A couple of pictures are up at [1]
Planning on what to do to the front. [2]
