Abstract
A method for the design, manufacture, and assembly of modular lattice structures composed of cuboctahedron unit cells.
Claims16
A cuboctahedral lattice structure comprising:
- a plurality of cuboctahedron cells faces molded using a two-piece mold, each face composed of a plurality of beams that form a substantially closed polygon substantially in a single plane to form an empty area in said plane encircled by the plurality of beams, each said face comprising joints in the single plane offset from polygon corners;
- the cuboctahedron cell faces assembled into cuboctahedron cell voxels;
- and
- a sufficient number of said cuboctahedron cell voxels attached according to a chosen lattice pitch to form a cellular lattice structure by connection of said voxels together through attachment of corner-offset joints in adjacent voxels.

A cuboctahedral lattice structure comprising:
- a plurality of cuboctahedron cells faces injection molded using a two-piece injection mold, each face composed of a plurality of beams that form a substantially closed polygon substantially in a single plane to form an empty area in said plane encircled by the plurality of beams, each said face comprising joints in the single plane offset from polygon corners;
- the cuboctahedron cell faces assembled into cuboctahedron cell voxels by gluing, welding or riveting;
- and
- a sufficient number of said cuboctahedron cell voxels attached according to a chosen lattice pitch to form a cellular lattice structure by connection of said voxels together through attachment of corner-offset joints in adjacent voxels.
