Abstract: The past 3-4 years has seen a transition in the use of Additive Manufacturing techniques from prototyping to series production. There remain a number of technical challenges that need to be resolved in order to increase adoption of the technology across a wider range of markets, one of which is improved part-to-part consistency. It is recognised that one factor that can influence the consistency of the laser based powder bed fusion process is the ageing of the metal powder used to manufacture parts, that is to say how the properties of the powder change following repeated used in repeated build cycles. Whilst commercial powder producers can exercise tight control over the 'as received' powder, changes that can subsequently occur following exposure to repeated process cycles in the laser beam melting machine warrant separate investigation.
