Background

The customer needed to reduce unsprung mass while maintaining bracket stiffness for better handling response.

Solution

Using DEMFlex One conformal lattice design:

  1. Initial lattice distribution along load paths
  2. Multiscale simulation for local and global stiffness
  3. Topology optimization under AM process constraints
