What is a common synonym for rapid prototyping?

Rapid prototyping refers to the quick fabrication of physical models using computer-aided design (CAD) data, typically through processes that create parts layer by layer. This technique is fundamentally linked to additive manufacturing, where materials are added together to form the final product. Additive fabrication encompasses various methods, including 3D printing, where prototypes can be created quickly and efficiently for testing, validation, and design improvement.

The relationship between rapid prototyping and additive fabrication highlights the flexibility and speed at which complex designs can be realized, helping companies reduce time-to-market for new products and innovate more freely in product development. This contrasts with other manufacturing methods that are either assembly-based, subtractive, or focused on producing finished products, which do not emphasize the rapid generation of prototypes for initial testing or design iterations.
