Semi-hollow or Fully Trabecular Topology Optimized Total Joint Replacement Implants

Unmet NeedOver 2 million joint replacement surgeries are done per year in the United States. However, the biomechanic functionality of joint implants is often limited because of the large discrepancies between the native bone of the patient and the material and structural properties of the metallic implants. In addition to the material of the implant...

3D Woven Lattices for Drag Reduction and Turbulence Reduction

UNMET NEEDThe reduction in fuel consumption and the subsequent reduced cost of logistics in transportation is an urgent need. Although technology is being developed to improve efficiency of engines used in ground transportation, a more effective target for technological development is reducing aerodynamic drag (which uses up over 50% of a road vehicle’s...

3D Woven Lattices as Multi-functional Heat Exchanger

Unmet NeedPorous materials are a widely used heat exchanger for common household items such as radiators and refrigerators. However, these materials are typically focused on optimizing at most one or two physical/chemical properties (heat transfer, fluidic permeability, electrical conductivity, etc.). As a result, these materials tend to underperform...

Topology Optimization Software for the Design of 3D, Additively Manufactured Mechanical and Structural Components

Unmet NeedTopology optimization is a mathematical approach that optimizes material layout within a given design space, for a given set of loads and boundary conditions such that the resulting layout meets a prescribed set of performance targets. It can be used to design components that minimize the amount of mass used to make a component while staying...

Optimization Tool for Establishing Minimal Families of Cold-formed Steel Sections for Production

The invention is a new algorithm that produces a family of minimal weight cold-formed steel lipped channels with the smallest number of individual cross-sections (family size) that are still capable of covering the current engineering design demands as commonly found in light steel framing. The algorithms shows that a new family of shapes with only...

3D Lattice Weaves with Tailored Damping Properties

Unmet Need Vibrations that occur within high speed rotary devices, such as turbines, can lead to excessive wear, fatigue, or failure. As a result, technologies to reduce vibrations within these components may result in substantial savings. Although polymeric materials typically offer excellent damping properties, they are not feasible in high temperature...
