echnical comparison of powder flowability at 25°C and 150°C, showing smooth powder behavior at room temperature and clumped, uneven flow at elevated temperature.

Split-screen technical image comparing powder behavior in a shear-style test setup at room temperature and elevated temperature. The left side shows a smooth, even powder bed at 25°C. The right side shows the same type of powder bed at 150°C with more uneven flow, clumping, and disrupted surface behavior. The visual supports the article’s message that flowability rankings and failure modes can change when powders are tested under process-temperature conditions.
