title: Optimizing porous lattice structures for orthopaedic implants.
abstract: Porous lattice structures are increasingly used for tissue and implant device design, and require precise structural characteristics such as stiffness, porosity, volume fraction and surface area. A non-uniform distribution of these properties may be required to suit design requirements or to match in-vivo conditions. Thus, porous lattice design is complex due to competing objectives from the distributed structural properties. A lattice structural design and optimization methods is presented using global objective functions for effective stiffness, porosity, volume fraction and surface area.
