What is minimum feature size?

• A. The smallest scale at which a feature of a particular shape in a particular orientation can be manufactured.
• B. The largest feature that can be printed.
• C. The color resolution limit.
• D. The minimum material thickness.

Answer: (A)

Minimum feature size is the smallest detail a 3D printing process can reproduce for a given geometry and orientation. It depends on the printer’s resolution and how the material is deposited or cured, including factors like nozzle or laser spot size, layer thickness, and how the material flows and solidifies. The statement that describes the smallest scale at which a feature of a particular shape in a particular orientation can be manufactured best captures this idea, because it emphasizes both the geometric detail and how orientation affects printability. The other options describe different limits—largest feature relates to build volume, color resolution is about color capability, and minimum material thickness concerns how thin a wall or layer can be, not the smallest visible or functional detail.
