We’ve traditionally built bridges and structures from trusses because beams are easy to manufacture, but in nature, trusses don’t exist, but voronoi patterns do. It’s nature’s “truss” essentially. Cellular Tissue forms in 2D and 3D voronoi patterns/volumes. Molds, fungi, Bone marrow, wings of insects, in stems and stalks of plants, heck, a honeycomb in a beehive is just a very specific type of voronoi pattern.

3D Printing as well, we are starting to see Voronoi 3D-printed casts instead of traditional plaster-poured casts. I mean, I guess we can’t even call it a cast any more because it’s not “cast” it’s printed/extruded. It’s just a limb-fracture ligature support or however you want to call it. Prosthetics and Bioengineered materials. No longer being limited by traditional manufacturing, like casts, forges, and milling, 3D printing allows man-made structures to have more optimized shapes determined by finite element solutions that end up looking like voronoi designs.
