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.
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.
