摘要

A process anomaly detection system for a three-dimensional additive manufacturing device, which carries out additive modeling or additive shaping by emitting a beam onto a powder bed, determines, based on a detection result of a shape measuring sensor, that a deposit anomaly of the powder bed occurs if at least one of a first condition that a Average height of the powder bed from a reference position is outside a first predetermined range, or a second condition that a height variation of the powder bed is outside a second predetermined range is fulfilled.
