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. ![]()
Thats awsome work Povilas.
Thank you!
Titanium + Labor = $$$$
That´s awesome!!!

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.
Well, it’s beautiful
more cool works on titanium!
Thank you, seeing your works on titanium was an inspiration! I’m currently experimenting with printing dithered raster images on titanium, will post my results and the process here when I have something good to show.
Change of thickness will cause a shift in colors. You mention this when it’s off center.
I have given up, don’t have the time and/or money to pursue color with my fiber.
They do look great.

It is a big pain for sure, but as they say no pain no gain.
Doing it because I love learning and as a hobby for the sake of the art and craft and not for profit is a key that helps a lot.
Doing it in steps helps, first you discover some colors, then imagine and do tests on what dimensions/parameters influence the colorful patterns and do iterative tests until you gain some intuition, then do bigger tests and so on. Multivariate testing helps reduce time, but is a pain in itself, as you have to keep multiple variables in mind.
