Abstract Scope |
Additive manufacturing (AM) processes such as Laser-Powder Bed Fusion (L-PBF) have gained interest due to their ability to manufacture parts with complex geometries. However, the properties of material manufactured by L-PBF can vary widely between different manufacturing parameters, systems, and manufacturing sites. This results in the need for extensive qualification processes for L-PBF systems, which must be repeated with each system and whenever any change is made in the essential manufacturing parameters. To improve the qualification process, Naval Surface Warfare Center, Carderock Division (NSWCCD) has led a round-robin study to examine the repeatability of L-PBF material manufactured on different AM systems across different warfare centers. This study examined the material properties, including microstructure and tensile properties, of 17-4PH stainless steel printed on six different L-PBF systems by three different manufacturers. Correlations between the tensile properties and microstructure were examined across builds manufactured at different warfare centers with different AM systems. |
