Design for Additive Manufacturing (DFAM) is a design approach that utilizes 3D printing technology. This approach aims to make the best use of the characteristics and advantages of the 3D printing process. DFAM allows designers to optimize their products, enabling them to design lighter, stronger, more efficient, and more economical parts. Unlike traditional manufacturing processes, this approach enables part production by adding material layer by layer. Among the main goals of DFAM are maximizing the advantages of 3D printing technology and optimizing the design process. This approach takes into account the requirements and limitations of the 3D printing process at every stage of design. DFAM makes the design process more efficient and provides benefits such as improved performance, cost savings, and enhanced production process.
