The market for additive manufacturing in the general and commercial aerospace industry has undergone several radical changes over the past three years, all targeted toward implementing the AM process in part manufacturing. Although following very different dynamics, these changes concern both the metal AM and the polymer AM (metal replacement and composite) segments. Most of the new evolutions in the AM market indicate a continued and sustained growth in the adoption of metal 3D printing systems, along with rapid technological evolutions primarily on three major fronts: speed, size and process automation. The number of hardware system suppliers has increased dramatically; the number of adopters for end-use part production is also now increasing more rapidly. AM for civil aviation is now closer to serial part production for both polymers and metals. While actual serial production by AM is still limited in size, several processes have been implemented to industrialize, understand and optimize the process.
