I just got into laser engraving recently with the Ortur Laser Master 2 with a 10W laser module, and I’m looking to do some work with some black anodized aluminum cards. I’ve gotten some tests with different power settings like 3-5 mm/s with 100% power and 2-3 passes, and it does leave a little bit of a mark, although it is pretty faint and you’d have to look very closely to see it. Is there a way I could potentially make it so that we can see the engraving on the card a little bit better, whether it’s changing some setting or doing some cleanup afterwards?
Translated:
180mm/m to 300mm/m
100% power
2-3 passes
Compared to:
2500mm/m
30% power
318 LPI
1 pass
(I use these settings on 2 different 10w machines.)
You are borderline cooking them. If they were painted rather than anodized, you would smell it. My settings are for painted glossy and matte, and for anodized, all black. Because they can show such detail, a good focus is required to get that detail.
After you mark them, wipe them with a microfiber cloth. That will bring out the detail of the print.
Had reached out for this machine and found out it is a diode laser engraver. If you would like to engrave on metal materials like anodized aluminum, fiber laser engraver is the perfect mahcine for this job. I had seen some people use laser spray on metal cards for diode laser engraving on metal, which can leave a obvious result on that, but I never tried, just a suggestion.
And for the parameter settings, you can use 100% power with 200-300mm/m speed.
This kind of engraving speed is used for laser cutting, usually.
