“…The printing velocity and curing characteristics of the printing material enter the model after transforming the mathematical formulation in vertical wall direction from Lagrangian to dimensionless Eulerian coordinates. The two basic curing processes considered are linear curing and exponentially-decaying curing, where the latter type is representative of accelerated curing obtained under the application of an external stimulus, e.g., UV light or heat [11,12] , or through a modification of the chemical composition [13] . The effect of geometrical imperfections is added to the model formulation, and the combined analytical-numerical solution procedure is presented.…”

“…AM refers to processes used to create a 3D object in which layers of material are formed under computer control. The use of this technology for stent manufacture is recent [57][58][59][60][61][62][63][64] and could be a really interesting method to produce stent. Mainly, there are four different AM technologies in the stent field.…”

From the introduction of stents, nobody was able to predict the advances that will occur in stent technology over the upcoming decades. Since their appearances, it became evident that this device had significant limitations, such as vessel occlusion and/or restenosis. Despite that, this medical device is the best clinical solution for cardiovascular vessel occlusions. Stents require a deep analysis, in terms of thrombogenicity, manufacturing process, geometrical aspects, and mechanical performance, among many other characteristics. The surface quality obtained in their manufacture process is crucial to blood compatibility, prevents the activation process of thrombosis, and improves the healing efficiency. The forecast stent market makes necessary continuous studies on this field, which help to solve the medical and engineering problems of this device, which are in constant development. Stents have been the center of many research lines over the last decades. The present chapter aims to summarize the state of the art of this medical device in the last years in the fields of design, manufacturing, and materials.

High-efficiency formation of personalized stent by additive manufacturing (3D printing) has gained deal of attention and research in interventional and personalized medicine. In this article, the structural characteristics of vascular scaffolds and the application and innovation of additive manufacturing technology in the process of angioplasty are reviewed. In the future, with the continuous maturity of additive manufacturing technology, it is expected to be an important part of interventional precision medicine to manufacture personalized vascular stent.
