Why can CO2 laser marking machine engrave non-metals?
This is because CO2 laser and fiber laser have different wavelengths, so it is good at engraving and processing non-metallic materials. 10W to 100W is fine if it’s just simply marking or engraving on the wood. If you want to mark large format and deep graphics, you have to choose a higher power CO2 laser marking machine.
Can fiber laser marking machine mark non-metals?
The answer is yes, but only some non-metallic materials can be marked.
