Pretty colors on titanium

Hello, beautiful people of Lightburn community, I’ve been practicing doing work with larger (10x10cm) color engravings on titanium (GR5/Ti-6Al-4V alloy) using a 60W MOPA. After so many ruined samples and so much testing here are some of my better finished works. :grinning_face:

What thickness is the titanium sheet?
Is it similar to stainless steel, where thickness is directly related to how heating causes color changes?

Thank you! The sheets these are printed on are 1.5mm, but I think it was an overkill and have ordered 1mm sheets next, I believe they should be thick enough for colors to be stable (most likely something like 0.8mm should be enough). For titanium I found that the finnicky colors are affected much more by how much off-center the engraving is, though with painstaking testing you can find alternative settings for colors that are much less affected by that too.
