“…Hereby, an actual final Poisson's ratio improvement of 36% for PLA samples was achieved compared to the FE calculated Poisson's ratio of the reference unit cell (8). On the other hand, the final measured Poisson's ratio on TPU samples reached the same Poisson's ratio with the FE simulated unit cell (12). In addition, the possibility offered by powder bed fusion to evolve the auxetic geometry in further directions, thus creating 3D auxetic patterns, was presented demonstrating the auxeticity of ν = −0.22 in two transverse directions, i.e., in x-and y-direction.…”

Auxetic structures possess a negative Poisson ratio (ν < 0) as a result of their geometrical configuration, which exhibits enhanced indentation resistance, fracture toughness, and impact resistance, as well as exceptional mechanical response advantages for applications in defense, biomedical, automotive, aerospace, sports, consumer goods, and personal protective equipment sectors. With the advent of additive manufacturing, it has become possible to produce complex shapes with auxetic properties, which could not have been possible with traditional manufacturing. Three-dimensional printing enables easy and precise control of the geometry and material composition of the creation of desirable shapes, providing the opportunity to explore different geometric aspects of auxetic structures with a variety of different materials. This study investigated the geometrical and material combinations that can be jointly tailored to optimize the auxetic effects of 2D and 3D complex structures by integrating design, modelling approaches, 3D printing, and mechanical testing. The simulation-driven design methodology allowed for the identification and creation of optimum auxetic prototype samples manufactured by 3D printing with different polymer materials. Compression tests were performed to characterize the auxetic behavior of the different system configurations. The experimental investigation demonstrated a Poisson’s ration reaching a value of ν = −0.6 for certain shape and material combinations, thus providing support for preliminary finite element studies on unit cells. Finally, based on the experimental tests, 3D finite element models with elastic material formulations were generated to replicate the mechanical performance of the auxetic structures by means of simulations. The findings showed a coherent deformation behavior with experimental measurements and image analysis.

Thin-walled energy absorbing structures based on hybrid structural concepts have a lightweight benefit along with great potential of enhancing the crashworthiness characteristics. Inspired by the huge number of research investigations performed on novel additively manufactured hybrid metal-composite configurations and their latest developments, the current review article extensively reports the latest advances along with promising outcomes of the impact response of various additively manufactured hybrid metal-composite structures for crashworthiness applications. Specific consideration is given to the crushing performance of the hybrid structures fabricated from Fused deposition modelling technique. The significant additive manufacturing techniques, their material selections and exceptional customized structural designs explored in recent times are discussed elaborately. Crushing patterns obtained by hybrid energy absorbing structures under various loading conditions are recognized. Furthermore, comparison of various hybrid structures and their latest advances revealed the efficiency of the thin-walled hybrid configuration based on 3D printing techniques in terms of weight reduction, crashworthiness and energy absorption behaviour. This review article will serve as a catalyst to boost the scientific improvement of hybrid energy absorbing structures utilized as passive safety protective devices in modern vehicles.

“…Zhang et al proposed an interesting and comprehensive review of the most recent progress in the field of additively manufactured auxetic structures and compared and summarized the results of mechanical properties under quasi-static and dynamic loading, energy absorption and numerical simulations of different geometries (Zhang et al, 2020). Moreover, it was demonstrated that by varying the internal geometric morphology of the structures, it is possible to tune their final mechanical properties, such as the elastic modulus, damage mode, peak force and energy absorption (Guo et al, 2021). Using the most recent AM techniques, it was also possible to design a single structure with a nonuniform distribution of auxetic cells, that is, a geometry with tunable PR and variable deformation properties, built by connecting different elementary cells with different PR (Han and Lu, 2018).…”

Purpose The purpose of this study is to evaluate the 3D printability of a multimaterial, fully self-supporting auxetic structure. This will contribute to expanding the application of additive manufacturing (AM) to new products, such as automotive suspensions. Design/methodology/approach An experimental approach for sample fabrication on a multiextruder 3D printer and characterization by compression testing was conducted along with numerical simulations, which were used to support the design of different auxetic configurations for the jounce bumper. Findings The effect of stacking different auxetic cell modules was discussed, and the findings demonstrated that a one-piece printed structure has a better performance than one composed of multiple single modules stacked on top of each other. Research limitations/implications The quality of the 3D printing process affected the performance of the final components and reproducibility of the results. Therefore, researchers are encouraged to further study component fabrication optimization to achieve a more reliable process. Practical implications This research work can help improve the manufacturing and functionality of a critical element of automotive suspension systems, such as the jounce bumper, which can efficiently reduce noise, vibration and harshness by absorbing impact energy. Originality/value In previous research, auxetic structures for the application of jounce bumpers have already been suggested. However, to the best of the authors’ knowledge, in this work, an AM approach was used for the first time to fabricate multimaterial auxetic structures, not only by co-printing a flexible thermoplastic polymer with a stiffer one but also by continuously extruding multilevel structures of auxetic cell modules.
