Enhanced Compressive Performance and Energy Absorption in SLM-Fabricated 316L Arrowhead Auxetics via Tendon and Stuffer Geometry Modification

Abstract

This study investigates how geometric modifications in double-arrowhead auxetic lattice structures affect compressive behavior and energy absorption. Lattices were fabricated in 316L stainless steel using Selective Laser Melting (SLM) at relative densities of 5%, 10%, and 15%.
