This is a friendly community for everyone who wants to share their art with the world! Everyone is welcomed 🎨
Rules
AI Art: While we appreciate AI generated art, there are more appropriate communities to post that type of art to. Please keep posts to non-AI generated art only. This rule includes AI art that was then manually manipulated (e.g. drawing on top of something generated by AI).
Nudity: Nudity is and has always been a part of art, but it may be something that some users don't wish to see or cannot view in certain circumstances (e.g. at work). If your work contains nudity, please mark it as NSFW. Work that contains nudity that is not marked as NSFW will be taken down. As long as the NSFW tag is used, we welcome nude subject matter.
Spam: Please do not spam this community. Self promotion is fine if you just want people to be aware of your work, but blatant attempts at spam will result in the past being removed and possibly a ban. If you aren't sure if what you are posting is spam, please contact the moderator first.
Conduct: Be nice, and don't be a jerk. Constructive criticism is OK, but don't be mean. Encouragement is always welcomed.
First post here - I’ve been experimenting with creating art by selectively anodizing titanium. Patterning anodized titanium isn’t new, but this process allows me to create full pictures, which I think is the first time this has ever been done.
This piece started off as a photo of a beach at sunset that I color mapped into the anodized Ti spectrum and printed.
Ok, that idea and process and result is pretty fucking cool!
Thank you!
I think this is a very clever idea! Very cool! You mentioned that it was anodized to look like this ^[2]^. The colors, to me, are reminiscent of the colors that steel produces when heated ^[1]^. Is there any similarity in the process, or is this something completely separate?

Very similar! Both colors are formed by oxide layers on the surface, I think with stainless steel it's a mixture of iron and chrome oxides. In the case of titanium there is only one oxide, TiO2, which is transparent crystal (in thin forms). The TiO2 layer is thin, on the order of hundreds of nanometers so the colors you see are a result of light waves constructively and destructively interacting with the transparent layer of TiO2 on the surface of the titanium sheet.
Looks so cool!! Amazing idea and good work!!
Yooo that is tight!!
How did you use the printout to anodize with?
I make the print by anodizing - I have a pen plotter I converted for this and I use the cathode as my 'pen' to print the image.
So you have a kind of conductive "pen" on the plotter and run a voltage across it?
Exactly - my "pen" is a stainless steel nail in a 3d printed housing.
It would be neat to do this with stainless steel and a pen torch.
