What Makes A Metal Powder Suitable? Researchers Examine Powders in AM Processes

Written by David

Metal 3D printing is becoming a vital source of production for a wide range of industries today, and a unique underrstanding of the required materials continues to grow around it. To sift through the finer details of powder usage, German scientists Silvia Vock, Burghardt Klöden, Alexander Kirchner, Thomas Weißgärber, and Bernd Kieback reviewed current testing and evaluating methods in ‘ Powders for powder bed fusion: a review .’ While there are numerous different categories for using powder in additive manufacturing, powder bed fusion is the main process considered in their paper. Consequent powder properties can be subdivided, beginning at the lowest level with individual properties, in bulk, and then regarding how it behaves under certain conditions (in-process performance). Testing powders on the single particle scale is a standard, inexpensive exercise, while evaluating bulk-particle behavior and in-process performance are more difficult. As the research team began reviewing powders for suitability, […]
