Title:

Energy Absorption of 3D Printed Auxetic Lattice Under High-Impact Loading​

This study evaluates the impact energy absorption of 3D-printed auxetic lattice structures using Izod testing. Multiple geometries were compared to determine how design influences mechanical performance. Results show that lattice geometry significantly affects impact behavior, with the 3D honeycomb structure achieving the highest energy absorption. Structures with controlled deformation dissipated more energy than those with brittle or unstable failure. These findings highlight the importance of geometric design in optimizing impact-resistant materials.
