Name one advantage of using 3D printing in engineering.

Using 3D printing in engineering offers significant advantages, particularly in the realm of rapid prototyping and reduced manufacturing costs. This technology allows engineers to quickly create prototypes from digital models without the need for specialized tooling or extensive setup, facilitating faster iterations and design testing. As a result, engineers can evaluate and refine their designs more efficiently than with traditional manufacturing methods, which often involve extensive lead times and material waste.

Additionally, 3D printing can lower overall production costs, especially for small production runs or custom designs, as it minimizes material waste by building components layer by layer. This efficiency also opens up opportunities for complex geometries and customizations that might be prohibitively expensive or impractical to achieve with conventional manufacturing techniques. Thus, the ability to rapidly prototype and reduce costs makes 3D printing an invaluable tool in engineering.
