Backpack and lumbar pad

Abstract

Backpacks having lumbar pads as at least one component that has been manufactured using 3D printing or other additive manufacturing technologies. backpack may include 3D manufactured parts including a lumbar pad, shoulder harness, hip belt, or back panel. The component or lumbar pad may include a lattice structure that allows airflow or provides cushioning. The lattice structure may: have multiple layers, include a network of beams and nodes (e.g., that create cells), or be monolithic. The cells may be polygons (e.g., hexagonal) or cells may line up in multiple layers of lattice structure. Cells that line up may have equal numbers of sides. Other embodiments include systems for providing custom backpacks where consumers enter consumer body dimension(s) and the system fabricates a custom backpack or component using the body dimension or desired load capacity, for example, using 3D printing.
