Design for manufacturing is a methodological approach and research area focused on optimizing the design of products or systems to facilitate efficient, cost-effective, and high-quality production. It investigates the intricate relationship between design decisions and manufacturing processes, emphasizing the integration of manufacturing considerations early in the product development lifecycle to simplify designs, standardize components, minimize assembly complexity, and account for manufacturing process capabilities and limitations, ultimately enhancing manufacturability, reducing production costs, and improving time-to-market.
