Abstract Manufacturing of metallic products is currently facing a historic revolution driven by a group of innovative technologies clustered under the name of Additive Manufacturing (AM) or, more colloquially, 3D-printing. As opposed to the conventional subtractive manufacturing methodologies, AM is able to create net-shaped products by means of the addition, layer by layer, of the needed material. The biggest benefit of the AM in respect to the conventional manufacturing technologies is the substantial freedom the technology gives to the product designers in frame of the product development. Due to the relaxed geometrical constraints, complex parts characterized by optimized shapes can be realized. This can be translated in development of lighter and more cost-efficient parts and assemblies hitting two of the most important targets of the aeronautical industry. Furthermore, as a consequence of the significant weight benefits, the application of topologically optimized AM aircraft structures can provide with an important contribution in reducing the aircrafts fuel consumption and the relative emissions of CO2 & NOX gases, in line with the environmental targets of current aviation research programs. Despite the high investments, the AM still finds a limited applicability for the manufacturing of aircraft components. This is also due the challenges relative to the fulfillment of the Fatigue and Damage Tolerance (F&DT) requirements, particularly sensitive when they have to cope with innovative materials and technologies. This paper presents the state of art of the AM technology in one of the leading companies specialized in manufacturing of large aircraft components and offers a potential way forward toward the wider exploitation of AM technology potentials.
