RADIAL LATTICE STRUCTURES FOR ADDITIVE MANUFACTURING
First Claim
1. A physical object created by additive manufacturing, the physical object comprising:
- multiple beams connected with each other at junction points to form a lattice of the physical object;
wherein the beams of the lattice correspond to a duplicated three dimensional (3D) structure;
wherein the 3D structure has (i) first sets of junction points at a first location along an axis for the 3D structure, and (ii) second sets of junction points at a second location, which is different from the first location, along the axis for the 3D structure; and
wherein, when projected into a two dimensional (2D) plane normal to the axis, the first sets of junction points alternate with the second sets of junction points at successive radii positions away from the axis in the 2D plane normal to the axis.

Abstract
Methods, systems, and apparatus, including medium-encoded computer program products, for designing three dimensional lattice structures include, in one aspect, a method including: creating nodes in a plane normal to an axis in accordance with a spiral, wherein proper subsets of the nodes occur at successive radii positions away from the axis in the plane normal to the axis; repositioning every other one of the proper subsets, from at least a portion of the nodes, in a direction in 3D space along the axis; creating a three dimensional (3D) structure in the 3D space, the 3D structure comprising beams placed between the repositioned and non-repositioned proper subsets; duplicating the 3D structure one or more times to form a lattice in the 3D space; and selecting at least a portion of the lattice for inclusion in a 3D model.
