Moisture in Metal Powder and Its Implication for Processability in L-PBF and Elsewhere

The impact of moisture on flowability and spreadability is discussed. More notably we also present research the built nickel-base material. One lot a newly opened Hastelloy X (HX) L?PBF powder was split into two equal batches. batch moisturized using programmable climate chamber, other untreated. We bars with both batches for mechanical testing, in an EOS M100, cold build plate. content batches, before after build-jobs, were determined Karl Fischer titration (KF). Regarding periodical monitoring content, it not needed according to findings this paper. contributes slightly higher O?content material, turn, very slight reduction toughness. If purchased exhibits poor or high oxygen analysis oven-desorption followed by KF recommended. high, drying
