What is tolerance?

What is tolerance?

• A. The predicted range of possible dimensions for parts at the time of manufacture
• B. The exact final dimension of a part
• C. The color tolerance of a material
• D. The tolerance refers to the speed of printing

Answer: (A)

Tolerance is the range within which a part’s actual dimensions may vary from the intended size during manufacturing. It acknowledges that machines and materials aren’t perfect, so you specify how much deviation from the nominal dimension is acceptable. For example, a 50.00 mm feature with a tolerance of ±0.10 mm means parts can range from 49.90 to 50.10 mm and still be acceptable. This ensures parts will still fit together and function properly without forcing every part to be exact, which would raise cost and reduce yield. In additive manufacturing, tolerances depend on the process, material, and orientation, so they’re set based on what the system can reliably produce. The other ideas don’t fit because tolerance isn’t about achieving an exact final size, color matching, or printing speed. It’s about allowable variation in size.
