Topology optimization distributes material within a defined volume based on load cases, design constraints and objectives. This optimization process identifies where material can be removed and the optimal load paths for the component your designing. Not only does this result in lighter designs and less material consumption but stresses get evenly distributed, resulting in improved fatigue performance.
With the advances in additive metal manufacturing capabilities, lattice optimization — which generates optimized lattice structures — can now be incorporated in areas where a solid structure is not necessary. These technologies have been applied to medical implants and initial studies are very promising. Using optimization tools, medical implant stiffness can be manipulated to reduce problems such as bone re-absorption and lattice structures have been shown to greatly improve bone tissue infiltration.
This presentation will discuss a methodology and process to better tune the stiffness and strength characteristics of medical implants to improve longevity and performance.
