We just wrapped up 3 new bronze rings for our main interaction interface. The three rings are distinctly designed as molecular rings of H20, CO2 and the UREA molecule. Each one was printed with corn based plastic (PLA) on our new Ultimaker 3D printer in the DANM program at UCSC. Special thanks to Sean Monaghan for all the time and effort he put into the project. It was a wonderful experience exploring the process with Sean, of going directly from a 3D printed form to bronze ceramic shell casting without any loss of accuracy or scale. More pics to come of the final finishes on all three rings!
