3D-printed porous gyroid geometries tuned to match bone stiffness — reducing stress shielding in skeletal fixation hardware.
Skeletal reconstructive devices suffer from stress concentration and stress shielding when their stiffness doesn't match the surrounding bone. The goal was a stiffness-matching strategy that restores natural stress–strain trajectories after healing.
Explored Nickel Titanium with porous isotropic and gradient triply-periodic-minimal-surface (Schoen gyroid) pore geometries to modulate stiffness. Designed cubes were run through finite-element analysis to predict stiffness across pore configurations.
The specimens were 3D printed and experimentally tested, then validated against the FEA — establishing a repeatable way to grade lattice stiffness to bone. The interactive gyroid on the home page is generated from this geometry.
