In the context of additive manufacturing, what does 'design for additive manufacturing' (DFAM) emphasize?

'Design for additive manufacturing' (DFAM) emphasizes designing products specifically for functionality in additive manufacturing processes. This approach recognizes the unique capabilities and characteristics of AM, such as the ability to create complex geometries that are difficult or impossible to achieve with traditional manufacturing methods. By focusing on the design aspects that leverage these unique features, engineers and designers can optimize the performance, efficiency, and production of parts.

In DFAM, considerations such as minimizing material waste, enhancing structural integrity, and facilitating assembly are integral. The goal is to take full advantage of AM technologies, which may include varying wall thickness, incorporating lattice structures for weight reduction while maintaining strength, and designing for the specific extrusion or layering processes of a given additive technology. This understanding aligns the design process with the distinct possibilities and limitations inherent to additive manufacturing, ultimately leading to innovative, high-performing products.
