Up to one third of the production cost of an additive manufacturing component produced by powder bed processes (particularly metals) is the cost of the powder used, with commercial viability resting on establishing a robust supply chain and effective powder recycling strategies. More importantly, the chemical and physical properties of the powder directly impact the build process and final component quality and must be controlled and optimized to ensure process robustness and consistency. To achieve this, powder properties must be characterized at various stages in the supply chain, from new alloy development through to powder recycling. 

This online seminar, with a duration of 1h 45min, will provide an overview of four key analytical techniques that are commonly used to characterise additive manufacturing powders, including laser diffraction, automated image analysis, X-ray fluorescence and X-ray diffraction, and the benefits they offer.
