Abstract: Additive manufacturing (AM), or 3D printing, has become a transformative technology in mechanical engineering. It enables the creation of complex geometries and custom parts with unprecedented design flexibility and efficiency. This paper explores the various techniques of AM, including stereolithography, fused deposition modeling, and selective laser sintering, among others. It examines the wide-ranging applications of AM in industries such as aerospace, automotive, healthcare, and consumer products. The discussion includes current challenges in material limitations, surface finish, cost, and standardization, as well as future directions for the field, such as advancements in material science, hybrid manufacturing, large-scale AM, and sustainability.
