Cellular structures, also called Lattices, are structures composed by the periodic repetition of a basic minimal unit called "unit cell" in the space. This unit cell consists of a geometric structure, partially empty, which can be composed of beams, trusses or solids generated by analytic equations. Triply Periodic Minimal Surfaces are a class of periodic surfaces generated from trigonometric functions. When the sheet surface is thickened, the resulting porous geometry exhibits interesting properties, such as low density and good mechanical strength. Moreover, it is possible to tune the mechanical properties by modifying the parameters of the geometry, thanks to a modern approach to design called Field Driven Design.
