Abstract: Topology optimization has emerged as a pivotal tool in modern structural engineering, enabling the creation of highly efficient, lightweight, and performance-optimized structures. This paper reviews the fundamental principles, mathematical foundations, and current technological advancements in topology optimization methods, especially their integration with finite element analysis (FEA) and additive manufacturing. It also explores real-world applications ranging from aerospace to civil engineering, where optimized structures result in cost savings and enhanced structural integrity. Challenges such as computational cost, manufacturability, and multi-objective optimization are discussed along with ongoing research aimed at overcoming them.

Keywords: Topology optimization, structural design, finite element analysis, additive manufacturing, material efficiency
