| Abstract Scope |
Powder quality plays a significant role in defining the quality of the final components produced through powder bed fusion. Several issues related to powder degradation that can affect part quality include changes in shape and size caused by the formation of spatter particles. Furthermore, increased moisture content due to repeated handling and oxide formation on the powder surfaces will impact powder flowability and the mechanical properties of the parts. This study aims to understand the correlation between C103 powder collected from 14 different build cycles and changes in its morphology, flowability, and humidity absorption capability. Powder flowability will be assessed through various flow measurements, including dynamic angle of repose, packing density, dynamic flowability indices, and static charge collection. Finally, dynamic vapor sorption will determine whether the oxides formed on the powder's surfaces affect the humidity content it absorbs. |
