Abstract
The three-dimensional lattice structures disclosed herein have applications including use in medical implants. Some examples of the lattice structure are structural in that they can be used to provide structural support or mechanical spacing. In some examples, the lattice can be configured as a scaffold to support bone or tissue growth. Some examples can use a repeating modified rhombic dodecahedron or radial dodeca-rhombus unit cell. The lattice structures are also capable of providing a lattice structure with anisotropic properties to better suit the lattice for its intended purpose.
Claims22
A porous lattice structure for medical implants, the porous lattice structure comprising:
- a repeating unit cell, the repeating unit cell comprising a plurality of sub-unit cells;
- wherein:
- each of the plurality of sub-unit cells comprise six faces and is defined by a node centrally located within a cuboid volume;
- the node comprises a square bipyramid with eight node faces and a square plane parallel to a face of the cuboid volume;
- and
- each of the plurality of sub-unit cells comprises a first strut fixed to one of the eight node faces of the node defining that sub-unit cell.
