We have begun robotic fabrication of minimal surfaces (1-7). We are continuing digital and physical explorations of the wide range of such surfaces including spherical ones, toroids and linear/planar versions as in towers or horizontally spanning structures.

In an earlier experiment (8-13), the conventional brick was used to derive negatively curved units (saddles) as parts of continuously curved minimal surfaces. We were able to achieve this progressively, with the use of a CNC milled mold, starting with simpler brick vaults. The entire surface was subdivided into 4-sided saddle polygons with curved edges and a general brick-laying procedure was developed for all saddles. This used concentric rings from perimeter edges progressing to the center. Edges of saddles directed brick orientation in outermost rings, inner rings were laid “parallel” to these, and “seams” between edges were filled with customized bricks. Central regions of saddles required further customized bricks. The formalization of this procedure into a computational algorithm would be useful.
