Applications of Lattice Structures

Lattice structures have many applications, from automotive and aerospace to medical implants and consumer goods. 

  • Lightweighting: One of the most significant benefits of lattice structures is their ability to lighten objects’ weight while maintaining structural integrity. Lightweighting has become crucial in many industries because lightweight objects consume less energy and are more cost-effective and sustainable. 
  • Energy absorption: Lattice structures' exceptional energy absorption properties are another critical benefit. This makes them ideal for impact-absorbing materials like helmets and body armor; lattices help distribute the energy of an impact more evenly, reducing serious injury risk in these types of products. Lattices can also be used for vibration dampening and noise absorption in various applications. 
  • Thermal management: Lattice structures are also incredibly effective at managing heat. Their unique design creates a large surface area for heat dissipation, making them ideal for thermal management applications, such as heat exchangers.
  • Osseointegration: In the medical field, lattice structures are used to create customized patient implants to fit the exact shape and size of a patient's unique anatomy, improving the success rate of surgeries and shortening recovery times. Lattices’ porous structure also allows for the integration of cells and tissues, promoting bone and tissue growth that hastens the healing process.
