Hello I am getting ready to purchase my first laser but I would like some advise first. I would like to etch anodized aluminum on a curved surface without using a rotary. Is there some sort of formula used to determine if the surface has too much curvature for the size of graphic I would like to etch? Thank you for any help you may provide.
Fiber laser can do this because it has a very large focus area compared to diode or co2 laser.
