Xinhao Yin and Esosa Egharevba placed second in the graduate category of the 2026 Digital Manufacturing Challenge, organized by SME.
Their design used functionally graded TPMS lattices, designed in nTopology, for a high strength-to-weight ratio and good impact absorption. 3D scan data was used to fit the design to the wearer’s anatomy, and structural and impact simulations in Ansys and Abaqus were used to check how well it protects.
