Abstract Scope |
As laser powder bed fusion (LPBF) technology has transitioned from prototyping to end-use parts, understanding the role of the powder properties needed to reliably produce parts of acceptable quality becomes critical. In this study, different alloy powders from different manufacturers are tested for flowability, spreadability, particle size distribution, and morphology using scanning electron microscopy (SEM). The tested alloys include stainless-steel 316L, Nickel-based super alloy 625 (Inconel 625), M300 maraging steel (also known as Tool Steel 1.2709 and 18Ni300), AlSi10Mg, and Ti6Al4V. These powders were then used as feedstock in the Area Printing® process to print density cubes with a wide range of laser parameters to correlate the powder characteristics with part density. The results suggest a strong correlation between these characteristics and the density of the parts as well as among the powder characteristics themselves. |
