Powder Characterization At Low Stress State

April 17, 2020
Flow and stress fields are drastically different in 3D printers, die filling processes, powder inhalers or at the bottom of a huge silo. Therefore, in the framework of an application, the powder characterization methods have to be selected cleverly among the wide variety of available geometries and applied stresses. In powder bed based 3D printers, the confining pressure is low, the flow speed is relatively high and the free powder/gas interface plays an important role. Moreover, the density...

The Importance Of Powder Flow Characterization

March 17, 2020
“The success or failure of a product relies on the powder flow behavior during manufacturing.”WHAT IS POWDER FLOW?Powder flow, also known as flowability, is defined as the relative movement of a bulk of particles among neighboring particles or along the container wall surface [1].In other words, powder flowability refers to the ability of a powder to flow in a desired manner in a specific piece of equipment [2].Powder flow is thus a multidimensional problem where...
