Title: METHOD OF DETECTING PROCESS IRREGULARITIES BY MEANS OF VOLUME IMAGE DATA OF THE MANUFACTURED OBJECT
Abstract:
A method of training a detection system is able to acquire volume image data in an additively manufactured object for the detection of process irregularities, and comprises the steps of: a) receiving process irregularity data referring to a selected location within an additively manufactured reference object in which selected location a predefined process irregularity occurred during the additive manufacture of the object, b) acquiring volume image data of a volume of the reference object comprising at least the selected location by said detection system, c) identifying within the volume image data characteristic data which represent a difference between the volume image data of the selected location in comparison with the volume image data of at least one other location of the reference object and/or of a number of other additively manufactured objects in which no process irregularity has occurred and/or no process irregularity is suspected, d) assigning to the predefined process irregularity the characteristic data as a representative of the predefined process irregularity.
