It took me a lot longer than I expected to get this print out. In theory it was really straightforward, take my turtle image and feed it through similar code as what I used to make the jellyfish, but... I recently added a MOSFET into my print system so that I can control the anodizing current by pulsing that (instead of print speed/voltage), but it led to a ton of EMI issues messing with communication with the motor controller. After changing my grounding paths many times and receiving a few fun 200V shocks I just re-wrote my controller code to be more fault tolerant, and that seems to have done the trick!

New style! Kaleidoscope, medium is still anodized titanium because I'm a one trick pony :D

This has been a fun one - I was testing using more traditional pen plotter techniques (wiggly lines) to drive color instead of dwell time. It's really interesting how it comes out, the way the anodizing affects neighboring lines create a bit of a natural averaging that makes the whole thing look 'higher resolution' than the same thing drawn with just ink. Here's a closeup of the lines - pretty cool!

New print! This one played with a new technique. I noticed there is a speed that makes resonant vibrations in the pen plotter. This entire print runs at that speed, giving the colors some texture from the vibrations. The color variation comes from repeated passes over the same areas.

Another titanium print! This one is super geometric - the basis of the print is just a bunch of squares/diamonds rotated around a central point, the visual complexity comes from the combination of how they overlap and motion control of my pen plotter (specifically that it needs to accelerate and decelerate as it changes directions).

I've been playing around with more abstract stuff lately - I'm doing a series of prints that are basically just weird circles, hence the goofy old timey name of cyclometry :) The colors on this came out really neat in person!

Newest titanium print! It's of a region in the Eagle nebula, originally captured by the Hubble telescope. Space seemed like a cool place to explore a little more of the colorspace available in this process. Plate is 12"x18", image is ~9.5"x14".

I'm really happy with how this one came out, the background 'sky' is a gradienting deep iridescent blue, and the nebula itself hits some cool magentas, yellows, and a bluish-green that can't make its mind on what color it wants to be depending on angle and lighting.

Apologies for the less than stellar lighting. This was my biggest print so far, just under 18"x 18"! I'm really happy with the details, but printing something this big was definitely a learning experience for me. It took 3 attempts to get this image out, but I learned a lot about tubing management and maintaining chemistry I can think about while I sand down my previous botched attempts :D

Another anodized titanium piece - this one is playing with line work. The color variation is from varying dwell time, which changes for each hexagon in a rolling pattern, as well as from the interactions between the hexagons.

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.
