1. Understanding Additive Manufacturing in Aerospace

1. What Is Additive Manufacturing?

Additive manufacturing refers to a family of processes in which materials are joined layer by layer to build a part from a digital model. Unlike conventional subtractive techniques—such as milling or drilling—AM minimizes waste and enables geometries previously impossible to manufacture.

For aerospace applications, AM processes typically use:

2. Why Aerospace Needs Additive Manufacturing

Aerospace is one of the most demanding industries in terms of:
