2. Current additive manufacturing resources

2.1 Aeronautics needs

In the aeronautics sector, parts that can be additively processed are extremely varied, and involve a wide range of materials. They range from aircraft belt buckles to passenger cabin partitions and engine parts.

The choice of material is obviously linked to the structural and functional properties that will be sought, with the parallel objective of making parts lighter. Thermal, acoustic, vibratory and electromagnetic properties may all be required, leading to the use of one or other of the FA technologies.

It follows that in aeronautics, different technologies can meet this multiplicity of needs.

There are, however, limitations in terms of the size of certain parts and the time required...
