    Anodised aluminium and 3W laser

    Hi

    I have recently acquired a 3w 450nm blue laser engraver with the hope of using it to engrave pet tags. I have tried engraving a couple of anodised aluminium tags and the laser seems to successfully burn the anodised layer, however the result is very dull. Was I wrong to expect it to show the metal underneath and if not how can I make this happen. Do I need a different tag material? Thanks. Rob

    Hi Rob,

    It's better to fabricate the metal with a fiber laser with 1064nm wavelength.

    Yes
    This is about all you can expect.

    Thanks for the replies guys, I have had a re-think on the whole laser thing and will look at a more powerful at a later date when I have the funds.

    3w 450nm blue laser is a toy, not a tool for job.
    CNC lasers, constructions, service
