This paper reviews recent improvements in additive manufacturing technologies, focusing on those which have the potential to produce and repair metal parts for the aerospace industry. Electron beam melting, selective laser melting and other metal deposition processes, such as wire and arc additive manufacturing, are presently regarded as the best candidates to achieve this challenge. For this purpose, it is crucial that these technologies are well characterised and modelled to predict the resultant microstructure and mechanical properties of the part. This paper presents the state of the art in additive manufacturing and material modelling. While these processes present many advantages to the aerospace industry in comparison with traditional manufacturing processes, airworthiness and air transport safety must be guaranteed. The impact of this regulatory framework on the implementation of additive manufacturing for repair and production of parts for the aerospace industry is presented.

Metal additive manufacturing in the commercial aviation industry: A review (2019, background): “Aerospace is one of the industries where AM can find most likely applications, and the major players like Airbus, Boeing, NASA Lockheed Martin are heavily investing in the development of this technology [10-12].”
An investigation on the effect of deposition pattern on the microstructure, mechanical properties and residual stress of 316L produced by Directed Energy Deposition (2020, background): “In general, AM processes are classified into two broad categories: Powder Bed Fusion (PBF) processes and Directed Energy Deposition (DED) processes [7,8].”
Laser powder-bed fusion of Inconel 718 to manufacture turbine blades (2017, background): “Among a wide range of possible applications of AM, interest is currently devoted to superalloys for aerospace, automotive, and chemical industry [8], where outstanding combination of mechanical properties and wear resistance is required.”
Improved fatigue strength of additively manufactured Ti6Al4V by surface post processing (2020, result): “Previous studies of L-PBF and E-PBF Ti6Al4V with rough as-built surface have shown that the fatigue properties is dominated by the rough surface rather than internal defects [3,4].”
3D printing in aerospace and its long-term sustainability (2015, methodology): “Using AM for these alloys results in high cracking tendency, hence to improve its mechanical properties generally a Hot Isostatic Pressing process is employed (Uriondo et al. 2015).”
Review: The Impact of Metal Additive Manufacturing on the Aerospace Industry (2019, background): “As a result, the energy supplied by the electron beam is not only enough to melt the powder; it also increases the negative charge of the powder [22,45].”
The barriers to the progression of additive manufacture: perspectives from UK industry (2018, background): “…Flynn et al., 2016; Gu et al., 2012), a parameter within the process (Spears and Gold, 2016; Thompson et al., 2016; Yang and Zhao, 2015), a material (Gorsse et al., 2017; Mertens et al., 2017) or a certain application (Femmer et al., 2016; Guo and Leu, 2013; Li et al., 2015; Uriondo et al., 2015).”
Review of in-situ process monitoring and in-situ metrology for metal additive manufacturing (2016, background): “In addition, key reviews have been published in the area of applications and opportunities for AM techniques; these have centred around biomedical [6,7] aerospace [8], tooling [9] and general manufacturing [10].”
