What parameters ? Aluminum engraving diode laser 80w

This is my first attempt at engraving aluminum…
this is a 2x5w laser wid sold as 80w … is there a tutorial on how best to approach this ? how am i sure i got the best raufgeholt when engraving ?

What settings should I use for a logo in the same gray color?

These lasers are only really capable of use on anodized or coated aluminum to remove these coatings…

Most of what you find is for 20W and yours is a 10W…

However, you are getting results… It looks like the interval is too large. It’s always nice to know which is what axes…

You will need to get a few you can use for scrap and use the Laser → Materials Test to figure out the best combination…

Good luck

Thanks for the info… is hard as I realize… in the test I have not even caused a scratch with the 10w with untreated aluminum :wink:

what I have lasered there for the test is probably a direction …

but what else … can you engrave powder coated aluminum ? (diode laser)

If it’s anodized or coated you can probably lase it off… for any laser to work the material has to absorb the lasers frequency… metals like aluminum not only reflect over 95% of the energy, but the little heat created is drawn away quickly by a high heat conduction rate…

The only other way to mark metal is to anneal/oxidize the metals surface. Don’t think you have enough power for that…

must the material absorb the laser frequency? :smiley:

Dude then help me even more ^^ and tell me how to check this ? according to which recipe :wink: I check whether a material swallows the reader frequency or not -.- and whether painting can help ?

You can see though glass… but it is opaque to the frequency of a co2 laser. The co2 can engrave directly on glass, a visible laser cannot.

The beam heats these molecules and damages them… in glass it shatters, very small but still it shatters. The co2 can also engrave/cut acrylic effectively…

As a general rule, visible and co2 lasers are for natural materials and fiber are for man made. This isn’t totally true, but generally speaking… Acrylic is not natural, but the co2 cuts it well.

A visible light laser needs something that can be indirectly heated applied or in contact to cause damage to the material. Many use tempera paints, black markers and so forth…

You safety glasses should block the frequency of your laser, meaning it should be able to damage/cut it.

Make sense?
