The present study aims at developing reusable metamaterials fabricated by 4D printing technology. Honeycomb were manufactured via fused deposition modeling (FDM) with shape memory polymers (SMPs). reusability of these was determined through cyclic cold programming experiments, where each cycle involved a loading-unloading-heating (shape recovery)-cooling process. novelty this paper lies not only in experimentally demonstrating the recoverability reversing plastic deformation based on effect SMPs, but also studying their SMP under and materials unit-cell types mechanical degradation. results reveal that, one single compression cycle, polylactic acid (PLA) hexagonal honeycomb dissipated 22% more energy than polyethylene terephthalate glycol (PETG) counterpart because higher elastic modulus PLA leads to larger critical buckling load for segments structures. Furthermore, PETG re-entrant 25% due its negative Poisson's ratio overall uniform pattern. More importantly, it is found that multiple cycles, maintained an dissipation capacity 78.3% Cycle 6, nearly 3.5 times as result better ductility PETG. Moreover, could be reused 17 while 12 cycles. This unit cells are failure-resistant less concentration deformation. demonstrate constituent unit-cells failure resistance can reduce degradation, thereby exhibiting metamaterials.

Abstract Bistable laminates have potential applications in areas such as buffer and soft robotics due to their two stable states ability deform through both snap-through snap-back processes. However, conventional orthotropic bistable with state configurations snap loads are similar magnitude. There is a problem that the deformation cannot be easily driven when laminate stiffness high. To solve this problem, clever design needed reduce load increase so can realized more easily. In paper, we propose method suppress control of by utilizing shape memory 3D-printed polymers (SMP), which enables while reducing driving force. First, numerical model viscoelasticity established study its characteristics, results compared experimental good agreement. The effect SMPs on principal curvature also investigated. Finally, interlayer interface bonding examined microscopic perspective. demonstrate 3D printed effectively enhance laminates, achieving suppression maintaining interlaminar carbon fiber composites. This provides new insights practical significance for active structures.
