1. An additive manufacturing machine comprising:
a powder depositing apparatus for depositing a layer of additive material on a powder bed;
an irradiation device for selectively fusing a portion of the layer of additive material to form a cross sectional layer of a part;
a melt pool monitoring system for measuring emission signals from the powder bed while the irradiation device is fusing the cross sectional layer; and
a controller operably coupled to the melt pool monitoring system, the controller being configured for:
identifying outlier emissions where the measured emission signals exceed a predetermined signal threshold;
identifying outlier clusters by assessing the spatial proximity of the outlier emissions; and
generating an alert in response to identifying the outlier clusters.
