Metal additive manufacturing is a method of producing metallic parts layer-by-layer. Some drawbacks, including anisotropyin mechanical properties, detrimental residual stresses, and the presence of columnar grain structures can affect the qualityand performance of additively manufactured metallic parts. Therefore, different industrial sectors have employed intuitiveancillary processes to improve the quality of additively manufactured parts. Of particular interest is in-situ ancillary processesthat are more applicable than other procedures due to their utmost importance to reduce manufacturing cycle time. In thisreview article, after introducing various metal additive manufacturing technologies, some of the common alloys utilized inthose processes were discussed. With an eye toward improving the quality of additively manufactured components, the focusof the review was then shifted toward the effects of building direction, processing parameters, and Alloying compositionModification on microstructure and mechanical properties. The efficacy of ancillary processes such as metalworking, in-situheat treatment, and in-situ thermo hydrogen process in reducing defects and improving physical and mechanical propertieswas then presented.
