Mechanical performance was evaluated through experimental compression tests and finite element simulations. Results indicate that increasing the unit-cell fillet radius significantly enhances maximum force, stiffness, and specific energy absorption (SEA) by 17–23%. Additionally, increasing unit-cell width produces up to a fourfold rise in peak force, substantial improvements in stiffness, and increases SEA from 191.5 to 236.6 mJ/g.
