ADDITIVE PRODUCTION OF AN OBJECT AND UPDATE OF A POWDER DATASET

摘要

The invention relates to a method for producing an object (100) with a powder-based additive manufacturing method. The invention further relates to a control (250) for a plant with a powder bed for producing objects with a powder-based 3D printing method, a coordination unit (300) for one or more plants (200) and a method for generating training data for neural networks. To indicate improved powder management for powder-based additive manufacturing processes, the following steps are proposed:-Providing a powder (40, 41, 42),– Providing a powder data set (D40, D41, D42) for the powder (40, 41, 42),– Production of the object (100) by selective solidification of the powder (40, 41, 42) using process parameters (P100),-Update the powder data set (D40, D41, D42) with at least part of the process parameters (P100) and/or derived parameters.
