<p>Additive manufacturing (AM) fabricates components layer-by-layer, where layers are joined through various melting or assembling processes. These processes are controlled by multiple parameters, affecting the microstructure and material properties of the additively manufactured components. This review explores the influence of process parameters on the tensile properties, fatigue behavior, fracture toughness, and fatigue crack growth behavior of powder bed fusion (PBF)-fabricated metal components. The PBF process parameters include building orientation, build layer thickness, and hatch spacing, along with post-fabrication treatments such as heat and surface treatments. The additively manufactured materials considered for this study include titanium alloys, steels, nickel alloys, and aluminum alloys. Based on this review, it is concluded that building orientation and heat treatments significantly influence the tensile and fatigue-fracture behavior, while surface treatments critically affect the high cycle fatigue response of PBF components. This comprehensive review provides valuable insights into the selection of process parameters essential for the optimal development of engineering components using AM processes.</p>
