Description
Qian Li and co-authors design porous titanium implants that flex more like bone in this 2023 study. The alloy Ti-6Al-4V is a standard implant metal, but its stiffness far exceeds bone, which can loosen implants over time. Its magnetic pull also clouds medical scans.
The team patterned the metal with irregular prism-shaped pores based on a Voronoi layout. Computer models varied pore width, spacing, and seed count to tune the structure. Samples printed by laser melting matched the models closely. The porous samples bent with stiffness close to human bone. Their magnetic pull measured at most half that of solid alloy, a gain for scan quality.
