||Convention powder flow rate test methods using static techniques, such as the Hall and Carney funnels, have been shown to provide insufficient and at times inconsistent information on the flow behavior of powders. With the growth of powder-based metal and ceramic additive manufacturing processes, the need for superior flow characterization methods has become paramount. The development of new powder flow standards involves a wide spectrum of entities, including instrument manufacturers, independent test laboratories, standards organizations, additive manufacturers, powder manufacturers and AM equipment suppliers. This symposium aims to bring together these users of powder flow data to share experiences and insights in the broad range of available static, quasi-static, dynamic, low stress and higher stress test techniques and where each may find suitable application. Of particular interest are cases where new methods provide a higher level of insight into flow properties compared to existing techniques, as well as cases where the two approaches show good correlation.
