Abstract

1. Method, in particular a computer-implemented method, for generating training data to determine potentially occurring deformations on a green part (5) which may occur during a post-treatment (6) of the green part (5) following an additive manufacturing process with which the green part (5) can be produced,comprising the following steps: - Providing model data for at least one green part (5) to be produced; - Providing at least one property of the green part (5) to be produced; - Segmenting the green part (5) to be produced into several segments (8) based on the provided model data; - Performing a simulation for each segment of the several segments (8) of the green part (5) to be produced concerning the post-treatment (6) of the green part (5) to be produced based on the at least one provided property of the green part (5); - Determining at least one process property for each segment of the several segments (8) based on the simulation performed, wherein the at least one process property of each segment is used to characterize,which influence the respective segment has on at least one adjacent segment (10) of the multiple segments (8) during the post-treatment (6); and- generating the training data based on the multiple segments (8) and the at least one process property determined for a respective segment of the multiple segments (8), wherein- a post-treatment cycle relating to the post-treatment (6), a green part density of green parts during the post-treatment (6), and / or an arrangement and / or an orientation of the green part (5) to be generated during the post-treatment (6) is provided, wherein the post-treatment cycle relating to the post-treatment (6), the green part density of green parts during the post-treatment (6), and / or the arrangement and / or the orientation of the green part (5) to be generated during the post-treatment (6) is taken into account when performing the simulation for a respective segment of the multiple segments (8),and / or- a geometry of a respective segment, a volume of a respective segment, a geometric configuration of a respective segment and / or a boundary condition concerning a respective segment is taken into account when performing the simulation for a respective segment of the several segments (8), and- on the basis of the simulation performed for a respective segment of the several segments (8), a force exerted by the respective segment on at least one neighboring segment (10), which can be brought about on the basis of the post-treatment (6), is determined, wherein a state of the segment (10) that is at least one neighboring segment to the respective segment can be changed on the basis of the exerted force.
