Influence of Manufacturing Factors on the Mechanical Properties of 3D-Printed Soft Architected Composite

Soft architected composites (SAC) have exhibited remarkable capabilities in terms of stiffness, ductility, and energy dissipation when subjected to compression conditions. The recent advancements in additive manufacturing have significantly propelled the fabrication of soft architected composites (SAC). To gain comprehensive insights into the mechanical behavior of additive-manufactured SAC, a comprehensive investigation was conducted to analyze the impact of various manufacturing factors on the mechanical properties of the SAC. The effects of printing machines depended on the printed architected core geometry of the SAC units. The compressive performance under cyclic loading was also studied. The damaged composites could still sustain more load with the displacement increasing during the load cycles. The architected cores with negative and positive Passion ratios were appropriate for small and larger displacement loading scenarios, respectively, when no damage was allowed for designing. The findings of this study have made significant contributions towards enhancing the manufacturing efficiency and practical engineering applications of SAC units.
