Laser engraving ceramic tile

Hi all,

we have some very nice grey-brown-terracotta-colored ceramic tiles. So I have set up a laser-job :slight_smile:
The 10W-laser cuts fine into the material, there is no smoke and no smell at all BUT there is a hissing sound and some glowing sparks are visible, so I stopped the job (I don’t want the laser-lens getting burned).

I wonder if anyone has tried that before or has information about “burning/lasering cermaic tiles”? What’s the glowing sparks?

Thanks a lot.
Tobias

I’ve done a bunch of ceramic tile and the sound is normal. The little spark bits are just superheated pieces popping if they have a little moisture. Dry them good first and it might help. Otherwise, it’s fine. :slight_smile:

Thanks. I thought so too about the sound, and it also may fit to the moisture that is vaporising.
Do you have any recommendations on speed and laser power?

I’ve had good results on bare glazed tile with 1000mm/m, 100% power, 0.15 interval.

Thanks, I’ll give that a try :slight_smile:
