1. Why additive manufacturing in aerospace

The aerospace sector has always been a force for innovation, particularly in :

• lighter structures ;

• the addition of new functionalities;

• and cost reduction in general.

What's more, the particularity of producing small runs of high value-added parts makes this sector a privileged industrial segment for the development of various FA technologies.

Cycle time reductions are made possible by the absence of tooling and the minimization of the amount of wasted material, resulting in productivity gains. Significant technical advances are still to come in terms of :

• new part designs (new "design", new functionalities) thanks to topological optimization ;

• ...
