Metal additive manufacturing (AM) is often billed as the future of manufacturing, providing unlimited possibilities in terms of part design and complexity, minimal material wastage and the ability to manufacture parts anywhere in the world through the internet. An aspect of AM that receives relatively limited attention, yet underpins the foundation that AM relies upon, is powder management. Powder bed AM processes typically use up to 20 kg of powder for each 1 kg of manufactured part. This means that AM users must be able to effectively handle and recycle vast amounts of powder during the process. In the current generation of AM machines the powder handling equipment provide a potential risk to both powder traceability and powder quality. This is largely driven by exposure of the powder to the environment and the use of non-optimal equipment.
