This work briefly reviews the classification of the different types of steels, the most common AM processes used for steel and the available powder feedstock. The characteristics of the as-built microstructure, including porosity, inclusions and residual stresses, and the importance of post-build thermal processing are emphasized. Finally, the material properties of AM steel parts are reviewed highlighting the importance of post-build processing.
