Abstract This paper explores the potential applications of 4D printing technology in aerospace field, with a focus on mechanical properties and reusability honeycomb metamaterials shape memory characteristics fabricated using polymers (SMPs). Currently, research SMP‐based is limited, particularly regarding influence cellular unit geometries their recovery performance, which remains unclear. To address this gap, study combines typical units positive, negative, zero Poisson's ratio into various structures. Through quasi‐static compression experiments, complemented by three‐dimensional digital image correlation (DIC) finite element analysis, performance deformation mechanisms three structures are compared detail. The patterns under elucidated, geometric shapes behavior response analyzed. Shape including single‐cycle multi‐cycle tests, designed to evaluate smart terms key metrics such as rate restoring force. systematically characterizes compressive different combinations, providing significant guidance for development 4D‐printed metamaterials. Highlights Metamaterial combining cells ratios. DIC FEM used assess effects failure. ZAZ structure shows superior stiffness energy absorption compression. Evaluate SMP loading conditions. ZAP exhibits more stable cyclic loading.
