What is a key advantage of using additive manufacturing in the production of prototypes?

The key advantage of using additive manufacturing in the production of prototypes is the speed of production. Additive manufacturing, or 3D printing, enables rapid prototyping, allowing designers and engineers to quickly produce models and test them for fit, form, and function. This process streamlines the development cycle, significantly reducing the time from concept to tangible prototype compared to traditional manufacturing methods.

Unlike subtractive manufacturing processes that involve cutting away material and can be time-consuming, additive manufacturing builds parts layer by layer, which allows for immediate adjustments and iterations in design based on feedback. The ability to quickly create and iterate on designs supports innovation and helps bring products to market faster, making it an invaluable tool in prototyping.

The other options highlight limitations or disadvantages—such as high manufacturing costs, restrictions in material selection, and complex assembly requirements—which do not align with the positive aspects of additive manufacturing for prototyping.
