Which of the following is a benefit of 3D printing?

• A. Greater customization
• B. Higher energy consumption
• C. Reduced supplier diversity
• D. Increased lead times

Answer: (A)

The main idea being tested is how additive manufacturing enables tailoring products to individual needs. 3D printing builds parts directly from digital designs in layers, which makes it easy to modify geometry, add personal features, or create customized items without expensive tooling. This capability supports rapid prototyping and on-demand production, so products can be adapted to specific requirements—precisely what “greater customization” means.

The other options aren’t benefits: higher energy consumption isn’t an advantage of 3D printing, it’s typically something to manage or minimize. Reduced supplier diversity would limit options and resilience, whereas 3D printing can enable distributed manufacturing and more supplier options. Increased lead times would delay delivery, while 3D printing often helps shorten lead times through on-demand production and reduced tooling.
