A group of multiple hollow fibers may be shaped to introduce angular divergence among the fibers, or to introduce a selected longitudinal oscillation into the fibers. In one shaping technique, the fibers are held in parallel while upper and lower crimping assemblies of parallel crimping bars are drawn together on opposite sides of the parallel fibers. When bars of the opposing assemblies draw sufficiently close, they sandwich the fibers in between them, causing each fiber to assume a shape that oscillates as the fiber repeatedly goes over and then under successive bars. Since the crimping bars are aligned at oblique angles to the fibers, the peaks and troughs of successive fibers are offset. While in this position, the fibers are heated and then cooled to permanently retain their shapes. A different shaping technique utilizes a lattice of crisscrossing tines defining multiple apertures. In this technique, the lattice and fibers are positioned so that each fiber passes through one of the apertures. Then, the lattice and / or the fibers are slid apart or together until the lattice holds the fibers in a desired configuration, where the fibers have a prescribed outward divergence relative to each other. While in this position, the fibers are heated and then cooled to permanently retain this angular divergence.

A unit cell for a lattice structure includes eight unit trusses disposed at vertices of the unit cell. A single unit truss is disposed at a centroid of the unit cell. Each of the nine unit trusses includes fourteen struts. Lattice structures are commonly used to connect various loads within a volume of space.

Additionally, conventional lattice structures are homogeneous, having dimensions and properties that are consistent throughout. These constraints, generally imposed for ease of manufacturing and assembly, prevent the development of highly robust and efficient structures, and limit the potential for multi-functional applications.
