This work explores the effects of repeated environmental exposure on the flowability and moisture content of aluminum 5056 and tantalum powder for end use in AM applications. Other important powder characteristics, such as particle size and morphology, are also considered in this analysis. A statistical analysis approach was utilized to observe trends between exposure conditions, powder characteristics, and powder behavior. The results of this study, as well as the proposed future work, are intended to inform powder-based AM users of the ramifications of powder handling and storage protocols on the processability of their feedstock so that optimal processing can occur.
