The purpose of this paper is to provide an overview of the available Additive Manufacturing (AM) technologies widely documented in many scientific papers and to attempt to answer the question of whether this technology could be used in the optimization of geometry for aircraft engine parts. The core research method in this article is based on the analysis of the scientific literature related to Additive Manufacturing gathered over the past two decades. The discussion starts with a review of various technological solutions, including Powder Bed Fusion (PBF), Direct Energy Deposition (DED) or Electron Beam Melting (EBM). The technological schemes of the processes or their differences are shown, as well as the advantages, disadvantages, and development opportunities. The article also attempts to divide AM technologies in terms of the materials used. The purpose of this approach is to simplify technology selection from an engineering point of view. At the end of this article, industrial ‘in-use’ applications in safety orientated aerospace market are overviewed. As a result of the literature analysis, an attempt is made to prove that modern additive technologies could be used to optimize integrated and complex structures like air bleeds in high pressure compressors of airplane powerplants.
