Simulation-driven optimization for additive manufacturing in aerospace and automotive applications

This review paper looks at how Additive Manufacturing (AM) has changed the aircraft and automotive industries. It focuses on how AM can make complex, lightweight structures that improve performance and efficiency. AM uses three-dimensional computer-aided design (CAD) models to build parts layer by layer, which gives designers more freedom and cuts down on waste. AM in the aerospace business makes it possible to make quick prototypes and parts that are better in every way, like engine nozzles and structural parts. Major firms like GE Aviation and Airbus gain a lot from this. Despite high costs and material constraints, AM is driving sustainable advancements in aerospace manufacturing. Similarly, in the automotive sector, AM technology facilitates the creation of customized, intricate parts, accelerating development processes and reducing waste. The article studies different modelling methods, like finite element analysis (FEA) and computational fluid dynamics (CFD), and compares and contrasts them in terms of how well they help improve design, material use, and mechanical performance. Additionally, it examines the diverse processes and materials used in AM and offers future recommendations to overcome current limitations. These concepts show how AM could change the way things are made in high-performance businesses, resulting in more creative and efficient ways to make things. This review bridges current gaps by analyzing simulation strategies aligned with aerospace and automotive requirements.
