In recent years much effort has been put into developing powders that are optimised for AM processes. As a result, a far greater understanding of the complex requirements for powders now exists. Particle size is widely recognised as a key property, but there is also an appreciation that particle shape has an important role to play. As Malvern Panalytical’s Debbie Huck-Jones and Cathryn Langley explain, finer particles are advantageous from the perspective of packing behaviour, but are typically associated with poor flowability, compromising processing efficiency. Controlling particle shape can help to alleviate this problem.
