Powder Flowability at Elevated Temperature: Why Room-Temperature Results Don’t Predict Hot-Bed Behavior

Temperature shifts surface energy, contact compliance, and residual moisture state in ways that can reverse a powder's ambient flow behavior. This Insight explains the dominant mechanisms across three temperature ranges and what elevated-temperature testing reveals for SLS powder beds, spray dryer outlets, and heated conveying systems.
