Rapid prototyping is the process of creating a physical sample of a new product design. It serves as a critical early step before mass production, allowing developers to verify that the final product meets expectations in terms of appearance, functionality, and performance.

Rapid prototyping does not rely on a single technology or manufacturing process. Instead, a wide range of production methods can be used, including CNC machining, 3D printing, injection molding, and sheet metal fabrication. These same techniques are often applied in both prototyping and full-scale production.
