I received a commission from a private party for a piece based on the Gyroid design, to be about 18" in size.

We talked by email about how this surface dissects into square-like and hexagon-like tiles, and how to work with it to highlight that.  I made this sketch:

Meanwhile I spoke with Steve at Reinmuth Bronze, and we thought about how to fabricate such an object in wax. 

The design we settled on is an assembly of identical modules.  I designed the first one in CAD and had it fabricated in plastic by stereolithography.

At the foundry, a rubber mold was made from this master and 27 wax copies were pulled.  They were assembled layer by layer into the complete structure:

This was dipped in a light slurry, then into coarser ceramic mixtures to form a hard mold around the wax.

Alley-oop!  The mold is heated to fire the ceramic and remove the wax, then bronze is poured into it.

Meanwhile I had a black granite base fabricated by The Base Shop in Colorado.

Luckily, they fit together well!

Someday I'd like to go to New York and visit this object.
