“…The study highlighted the shape memory effects of the considered structures as their Poisson's ratios and elastic moduli were programmed by tuning topological parameters. Zeng et al [ 212 ] explored the temperature‐dependent mechanical response of composite lattice materials made of continuous fibers and SMP. Isothermal compression experiments and thermomechanical cycle experiments revealed the shape recovery capability and relaxation phenomenon of the considered lattice materials.…”

Metamaterials, also known as lattice‐structured materials, imitate the multifunctionality of natural architects as tailoring their physical properties is associated with manipulating their microstructure. As the recent evolution of additive manufacturing enables the creation of intricate geometries with minimal material wastage, improving the design to manufacturing cycle of lattice structured materials has become one of the trending research areas. Triply periodic minimal surface (TPMS) and plate lattice materials are renowned for their exceptional mechanical behavior in lightweight applications. Apparently, several types of design optimization strategies are explored to maximize their performance for better biocompatibility and mechanical loading resistance. Some of these strategies include functional gradation and multimorphology hybridization that are comprehensively described in this review. Their benefits and drawbacks are highlighted with a focus on TPMS and plate lattice materials. The review anticipates the utilization of automated design exploration methods (i.e., topology optimization and data‐driven methods) to further enhance the design optimization procedure of lattice structured materials.

“…Polymer lattices combining high stiffness and toughness have been printed using core-shell filaments with co-extrusion systems that required specially designed printing heads with concentric cylinders. [15,16] Co-extrusion has also been used to build optical waveguides, [17] biopolymers [18], polymer composites, [19] fiber based supercapacitors with organic binders [20] or shape memory polymers containing metallic fibers [21,22]. In the latter case, the long metallic fibers are co-extruded as a wire inside the polymer shell.…”

“…As a result, the SMP spontaneously recovers its original shape. [13] Due to the unique programmable deformation ability, [14,15] SMPs have broad application prospects for biomedical stents, [16] flexible electronics, [17] and smart robots. [18] In recent years, the combination of the unique deformationrecovery ability and excellent biological performances has attracted much attention, and the SMPs based on biocompatible materials (polylactic acid, [19,20] polyurethane, [21,22] polyacrylic acid, [23,24] etc.)…”

In this paper, isocyanoethyl methacrylate (IEM) is used to functionalize the two ends of poly(ethylene glycol) (PEG) diol with acrylic acid groups through an urethanization reaction. The synthesized PEG/IEM resin is then photo-cured with a 405 nm ultraviolet lamp. T trans of the PEG/IEM resin can be regulated by the different molecular weights of PEG and the use of plasticizer Triacetin to reach 44 °C, which is closer to the human body temperature. Cytotoxicity assay and DMA shape memory cycling testing show that the PEG/IEM resin has excellent biocompatibility and shape memory properties. The flower structure is prepared and its shape recovery process is demonstrated. The performance of 10wt% nano Fe 3 O 4 /PEG4000/IEM resin and its composite spring stent structure satisfy the requirement of the stent properties in vivo, and can quickly recover to the original shape under magnetically driven. This work provides a material option for developing new biological application devices such as ureter stents.
