###### Abstract
The present study used a similar integrative approach with the application domain of fabricating aortic stents utilizing L-PBF. The aorta is the largest artery in the human body, piping oxygen-rich blood to all areas of the body. The pressure at which blood flows through the aorta can damage its wall over time, resulting in enlargement and bulging [17; 18]. An extra material, in the form of a metal skeleton within a fabric graft known as a stent, is implanted in the expanded area to keep the channel open for blood flow [19; 20]. The use of a patient's diagnostic history to customize the intricate metallic structure of a stent is a promising technique to improve clinical success [21]. As a result, L-PBF is a viable option for incorporating design complexity and manufacturing stents in a near-net form [22]. Support structures, on the other hand, are required to attain this goal, and their residue-free removal is a major challenge [13; 14; 15]. For the successful manufacturing of overhanging parts in aortic stents, it is critical to optimize the support structure design and develop cost-effective support removal procedures. [PERSON] et al. [23] established design rules for the manufacturing of cardiovascular stents employing L-PBF. As a rule, for constructing expandable stent meshes, the authors recommended avoiding the use of support structures during the stent design process since their size is similar to that of the stent struts. When support structures are integrated during design, the authors expressed concerns about the difficulty of removing them, as well as the possibility of injuring and deforming the stent during support removal. [PERSON] et al. [22] explored the L-PBF manufacturability of CoCr alloy stents for cardiovascular applications. Instead of conventional hatching, a concentric scanning method was used to produce a prototype stent that met the design rules for the L-PBF fabrication of filigree structures. With comparable surface roughness and micro-hardness values recorded for the bulk samples, it was reported that concentric hatching increased fidelity. ECP was reported to be a suitable post-processing strategy for manufactured specimens, with varying degrees of success depending on the scan strategy. The authors concluded that the L-PBF method, when combined with ECP, can be utilized to replace micro-tube manufacturing followed by laser cutting, which is traditionally used to manufacture standard cardiovascular stents. [PERSON] et al. [24] used the \(\mu\)-L-PBF (L-PBF with laser beam diameter less than 40 \(\upmu\)m) method to build stent-like structures from SS316L raw powders [25]. When appropriate laser beam parameters were chosen, high reproducibility was observed in the manufactured samples, which also had the required radial strength, acceptable elastic recoil, and good spatial resolution (60 \(\upmu\)m). After chemical polishing, the findings revealed a part density of >99 percent and excellent surface quality. This has led to the conclusion that \(\mu\)-L-PBF technology can be effectively used for the cost-effective manufacturing of complex-shaped vascular implants. The geometry of a stent, irrespective of application, is analogous to that of a lattice structure. This allows for the adaptation of concepts from the existing literature on lattice structures, including auxetic structures, in order to improve scientific knowledge, enhance stents, and support structure designs. [PERSON] et al. [26] investigated the deformation behavior of an auxetic stent with rotating square geometries manufactured by folding rigid squares and circular holes into a cylindrical shape using polyurethane sheets. The auxetic stents' enhanced negative Poisson ratio helped them to match the properties of native blood vessel tissues, in addition to the weight savings realized by the lightweight design. [PERSON] et al. [27] investigated the mechanical properties of chiral stents fabricated by selective laser sintering (SLS). Auxetic mechanical behavior was observed in the chiral stents proposed in their study.
