A major drawback of additively manufactured metallic components is their poor high cycle fatigue (HCF) resistance, which is primarily due to the presence of porosity in them. Keeping this in view, the effect of process parameters such as laser power (w), layer thickness (t), and scan rotation (ϕ) on...
