Case study | The impact of metal powder variability on AM build quality
LPW has conducted a study to evaluate the impact of metal powder variability during the Laser Powder Bed Fusion (LPBF) process. A series of density cubes were built from three different batches of AlSi10Mg using different atomising conditions. Nine cubes were built across a range of AM processing parameters, varying beam velocity and beam offsets.
