Which statement best describes the minimum feature size in relation to orientation?

• A. The minimum feature size is defined for a given orientation.
• B. The minimum feature size is independent of orientation.
• C. The minimum feature size describes color depth.
• D. The minimum feature size only applies to metals.

Answer: (A)

In additive manufacturing, the smallest feature you can produce depends on how the part is oriented in the build. This is because printers build layer by layer, so the resolution in the horizontal plane (the X–Y directions) is set by the printer’s capabilities for each layer, while the vertical progression is limited by the layer height. When a feature is aligned with the layers, you may achieve a different minimum size than when it is oriented so that its dimensions are built across multiple layers. Overhangs, supports, and the way material is deposited or cured also influence the final size of features depending on orientation. Because of these directional limits, the minimum feature size is defined for a given orientation to accurately describe what can be manufactured. It's not about color depth, and it's not restricted to metals—the orientation-dependent resolution applies across common additive processes and materials.
