Module 7 — Maintenance Practices

7.14.3 — Additive Manufacturing

Practice questions test what you know. This note teaches what you don’t.

Question banks train recall. The questions that decide a pass are the borderline ones, where two answers look right — and those are won by understanding. That is what this note is written for.

Inside this note

Locked

Additive manufacturing (AM), commonly known as 3D printing, builds parts layer-by-layer from digital models. Aviation increasingly uses AM for production parts, tooling, and prototypes. Understanding the techniques, material properties, and inspection requirements is necessary as AM parts appear in certified aircraft designs.
