What are the benefits of using metal in additive manufacturing?

Using metal in additive manufacturing notably enhances design flexibility and material properties, which is a significant advantage of this technology. When additive manufacturing processes are employed, such as selective laser melting (SLM) or electron beam melting (EBM), metals can be used to create complex geometries that are often impossible to achieve through traditional manufacturing methods. This capability allows for innovations in design that can incorporate intricate features, lightweight structures, and optimization of material usage, all while maintaining the strength and durability of the printed parts.

Additionally, additive manufacturing with metals can enhance specific material properties, such as fatigue resistance, tensile strength, and thermal resistance, due to the unique microstructures that can be achieved through layer-by-layer construction. This approach allows engineers and designers to tailor materials to meet specific application requirements, ultimately leading to improved performance of the final products.

The other options do not align with the primary advantages associated with metals in additive manufacturing. Factors such as cost and speed are often influenced by various aspects of production and may not inherently be benefits of using metal. Additionally, handling qualities such as weight depend on the design and application rather than being a direct benefit or drawback of the material itself.
