Engraving Aluminium



  • Hi folks!

    I have just tried to engrave something in an aluminium plate (50x20 mm).

    I was not very confident on having a good result, but to my surprise it finally came out quite good.

    I used a black edding 500 permanent marker pen to paint the surface to engrave first, let it dry for 1/2 min (yes, I hace no patience at all 😅) , then engraved and to finish I used solvent and a soft cloth to remove the black paint.

    Used:

    2.5W Elekslaser
    T2 Laser
    Resolution 0.1
    black edding 500 permanent marker pen
    Solvent

    As you can see in the photos below there is not much difference when using different speeds. I also tried with 2 passes and still not much difference.

    Hope it helps for your future engravings!!

    @alvar0.ga That looks really good, it's amazing what you can engrave with these low power diodes.



  • Well, i done this today and when i remove the black paint, the engraving disappear easily.

    Why?



  • Secondo me è solo vernice del pennarello bruciata, basta pulire bene e tutto scompare



  • Wow, It surprised me....
    I thought I couldn't engrave ANY metal materials with 2.5W laser.

    Thanks a lot for REALLY good information.

    @MightyBear It's not really engraving the metal but it does add pigment to the surface. There are commercial products like Cermark / Thermark that do this but they are expensive, using acrylic paint or markers is a cheap alternative but a bit hit-and-miss on results. I make a solution from brasso cleaning fluid and alcohol that seems to work well with my CO2 but not so good with the diode laser.
