Technique for Creamic tiles with diode laser
« on: January 05, 2018, 08:58:22 PM »
I found a new technique for Ceramic tiles and really like the results so I figured I would share it so other can give it a try. I have been doing a lot of work with the tiles on the CO2 laser and kept thinking there must be something I could do with the diode laser even if it won't cut the surface.

So what I am doing is taking white tiles and spray painting the surface with black paint, and after the paint dries I can burn some of the paint off. This is giving me a black tile with a white image. There is not gray scale since its a white tile with black paint so I can do black and white or dithered images. I have found that you need to make two passes to make it come out correctly. My first try was at 1500mm/min and found that I needed a second pass so the next tile I tried 750mm/min and it still needed a second pass - so I am sticking with the 1500 and making two passes. The first pass seems to always leave some of the paint on the surface and the second pass always cleans it up great.

Attached is a dithered image that I did tonight. Someone on this forum posted the picture quite a while back and I have kept a copy because its a great gray scale test.

have fun with it.

That is awesome wild bill! Thanks for sharing.
Question: how well does the image hold up? Does it scratch off easy?

I put a clear spray on after its complete to protect the surface. Actually its the same spray I use on slate after I etch it.

Yes how beautiful.

Had even thought of trying the same on a white tile, but lack of black spray paint in my house has made it only been at the thought. I have to go to town and buy something.    :D

very impressive results. So good you could sell them. Does the burning of the paint produce a lot of smoke or smell? I might have to hunt for some tiles now, and some gold paint...

I did not notice any smell burning the paint.

Next project is to see how well dithered images work with mirrors.

Line work (vector) also burns nicely into the a ceramic tile. I actually use two large white ceramic tiles as the base board for my A3 and you can see that the results of burning *paper* actually leaves a fairly decent non-removable mark into the glazing. I've scrubbed the tiles with various cleaners to remove soot so my papercuts doesn't get marked, but the engraved vector lines are permanent. They certainly don't come off no matter how hard I scrub.

iancia, what is the piece I see attached to the laser where it looks like it directs air? Is it on Thingiverse or somewhere?

Itís the focus ring from the Air Assist 3D printed module by @pawpawpaw85. It works well for 2.5W lasers but the air assist module no longer fits the bigger 2W module I replaced it with, so I rigged it temporarily with a cable tie to a hose running from my pump to the focus ring.

Any try to remove the shinny coat? It needs to be etched off.  This was a must when I worked in the marble and granite business. We used acid but that was the only way.  I know there are etching pastes at home depot.  Try the back side of the tile.  Maybe that will help.
