In laser powder bed fusion (L-PBF) additive manufacturing (AM), parts are fabricated in a layer-wise pattern from the powder feedstock. Therefore, the powder characteristics such as size, shape, chemical composition, and microstructure can affect the mechanical performance of AM parts. In addition, the powder characteristics may change while interacting with the laser and with the subsequent powder reuse strategy. Hence, it is essential to understand how the powder characteristics and its reuse can influence the structural integrity of AM parts by investigating the relationships between the powder and the material tensile and fatigue properties.
