Classification of additive manufacturing processes and relevant applications. Powder bed fusion (PBF) and directed-energy-deposition (DED) are the two most widely-employed techniques for printing functional metal components. (A) Pure-Copper component manufactured via EBM with internal core structure [127] (B) Porous Nickel-Titanium shape-memory structure enabled via SLM [128] (C) LMD (or DED) repair of SLM-based Inconel 718 fuel burner [39] (D) Porous Ti6Al4V components enabled via SLM technique [129] (E) Structurally-optimized titanium-alloy component enabled via SLM [122] (F) Titanium hip stems manufactured via EBM [130].
