Computer-implemented method for determining defects in an object manufactured using an additive manufacturing process

摘要

The invention relates to a computer-implemented method (100) for determining defects in an object manufactured using an additive manufacturing process, volume elements or spatial coordinates of the object to be manufactured being processed during the additive manufacturing process, the method (100) having the following steps: Determining (102) spatially resolved first process data of n objects that are recorded during an additive manufacturing process for manufacturing the n objects, the first process data defining a process data coordinate system for each of the n objects, determination (104) of measurement data of the n objects by non-destructive or destructive imaging Method after the production of the n objects, the measurement data for each of the n objects defining an object representation in a measurement data coordinate system, determining (106) which coordinates of at least a sub-area of the measurement data coordinate system are defect coordinates are associated with a defect in the object representation; Correlating (108) the at least one sub-area of the measurement data coordinate system comprising the determined defect coordinates with a corresponding sub-area of the process data coordinate system for collecting training data, training (110) an adaptive algorithm for determining defect coordinates in spatially resolved process data that is recorded during an additive manufacturing process for manufacturing an object were, by means of the training data, determining (112) spatially resolved second process data that are recorded during an additive manufacturing process for manufacturing an object, and analyzing (114) the second process data for defects using the adaptive algorithm .. This creates a method (100) , which enables potential defects of an object to be identified directly from process data arising during additive manufacturing.
