Which concept enables designers to quickly produce physical parts directly from digital models for testing?

• A. Rapid Prototyping
• B. Ergonomics
• C. Anthropometrics
• D. CAD

Answer: (A)

Rapid prototyping is the practice of turning a digital design into a tangible part quickly, using tools like 3D printing, laser cutting, or CNC milling. This approach lets designers test form, fit, and function directly from the digital model, enabling fast iteration and early feedback before committing to full production. The point is the speed and the ability to produce a physical part straight from the digital design for hands-on testing.

Other concepts don’t fit this exact idea. CAD focuses on creating digital models, not necessarily turning them into physical parts quickly. Ergonomics is about human use and comfort, not rapid fabrication. Anthropometrics deals with human body measurements, again not with producing prototypes.
