Abstract


This study focuses on the behavior of mechanical metamaterial structures under compressive loads and investigates the influence of production parameters on final properties of Kagome structures manufactured through stereolithography (SLA) using photopolymer resin. Tough 2000™ is a resin used for engineering applications developed by Formlabs, known for its high tensile strength, stiffness, and impact resistance and provides an ideal material for lightweight yet durable lattice designs. The study evaluates the influence of layer thickness on mechanical performance and the results revealed that increasing the number of layers reduces structural strength due to cumulative deformation effect and increases the ductility of the materials. The findings highlight the versatility of SLA-printed Kagome lattices for advanced engineering applications requiring lightweight, high-performance materials with tunable mechanical properties.
