“…Vellaparambil et al investigated the mechanical behavior of auxetic endovascular stents and they found that chiral stents can be used in conditions that require greater radial stiffness [139]. Furthermore, various researchers have investigated auxetic stents, including those by Asadi et al [138], Liu et al [116], Shirdel et al [147], and Xue et al [148]. Figure 13 exhibit auxetic stents employed during the research stages.…”

Auxetic materials, possessing a negative poisson's ratio, can be arranged in various geometric configurations, such as tubular structures. Unlike conventional materials, which contract in lateral dimensions when stretched longitudinally, auxetic tubular expands in response to applied forces. This review article amalgamates the latest experimental data and insights from preceding scholarly works, offering a detailed analysis of the structural design, fabrication processes, and mechanical characteristics of auxetic tubular structures. The review encompasses an analysis of their tensile properties, comparative evaluations with different materials, impact resistance, enhanced bending, and flexibility. Furthermore, the article explores the wide-ranging applications of auxetic tubular in diverse sectors such as automobile manufacturing, aerospace, medicine, and textiles. Additionally, investigated not only new suggestions and future considerations for the advancement of these materials and structures but also a rigorous examination of the forthcoming and new challenges. This multifaceted approach distinguishes it from prior studies within the same scientific domain.

Auxetic structures (AXSs) are a novel class of materials with unique mechanical deformation behavior associated with negative Poisson ratio. The combination of AXS configurations with various types of materials has unveiled a wide field of applications, including military high-velocity protection against explosions and ballistic projectiles. However, the characteristic geometric re-entrant model of AXSs imposes limitations and difficulties when using conventional manufacturing methods to assemble the structure lattice. Additive manufacturing (AM) has recently been explored as a more efficient and cost-effective method to fabricate AXSs, regardless of the type of material. This review paper focuses on the development and applications of AM processed AXSs. The review highlights the significance and great potential for this class of materials that can be produced relatively fast and at a low cost. The advantages of AXS/AM are expected to extend to important industrial sectors, particularly for military ballistic armor, where the feasibility for products with improved properties is critical. The use of AM offers a viable solution to overcome the difficulties associated with the conventional manufacturing methods, and thus offers greater design flexibility, cost efficiency, and reduced material waste. This review paper aims to contribute to the understanding of the current state-of-the-art and future research prospects for the production and applications of AXS/AM.
