I would strongly suggest against using a 40-45W laser as a stool softener.

I’ve been trying this technique. I’ve been able to get a good contrast on the image, but I get streaks. I don’t see them in the source image. I’ve cleaned everything. Anyone have any ideas?

I get those as well, I think they are caused by inconsistency in the thickness of the glaze on the tile.

Oh, OK thanks. I wonder if there are tiles that have a more consistent glaze. I was just using leftover tiles from a bathroom remodel.

I wonder if it’s the glaze on the tile or inconsistent spray of the paint?

I’ve wondered that too. White paint on a white tile, it’s hard to tell. I can orientate them at a 45 degree angle when I paint them. That should help determine where the effect is coming from.

Those are too uniform to be paint - unless the tile is 24" tall and you used a mechanical jig to apply it.
Variations in glaze would explain why some tiles work well and some don’t.

Made an attempt at what I think was what @kanati used in his test above, Here. I have some areas that seem lighter and i think it is because i am not cleaning away all the paint or some other residue.
After some more agressive cleaning the cabin looks better i think. i used a microfiber cloth and solvent.
I think the print took ~6hrs the tile is 10cm x 30cm

This was my last test using the vary power settings, if you don’t like spiders don’t click on this one hehe.
Here is my photo, it is of a brown recluse spider at my parents house.

Pre-application of large shoe? If I ran across a recluse it would look like this:

Yeah they didn’t last long after the photo, they are a bit to dangerous to have around 13 of them hanging out below and above the patio door outback. makes me itchy thinking about it.

Love it! I have, somewhere on one of my hard drives, a lot of spider pictures I took with a macro lens. They really are fascinating creatures. One in particular had the most amazing body armor with huge spikes sticking out everywhere. I f I come across those someday I may print one off.

Would love to see that once it is done
Of necessity I think the time is both needed and well spent to get the best look. folk don’t think twice about a 20 hour 3D print but are so used to 5 minute cuts they think 6 hours for an engrave is too much.
