Title:
DATA-BASED SYSTEM FOR OPTIMIZING POWDER BED FUSION ADDITIVE MANUFACTURING PROCESS
Document Type and Number:
WIPO Patent Application WO/2023/113449
Kind Code:
A1
Abstract:
Provided are a system and a method for optimizing a process on the basis of data collected in a powder bed fusion (PBF) additive manufacturing process. A system for optimizing an additive manufacturing process, according to an embodiment of the present invention, comprises: a data collection unit for classifying, by layer, data on process variables collected during an output preparation step and an output step of a PBF additive manufacturing process; a storage unit for storing the data classified by layer by means of the data collection unit; a classification unit for determining whether output is successful for each layer; and an analysis unit for analyzing the process variables for process optimization on the basis of the result of determining whether output is successful for each layer. Therefore, data generated during the output preparation step and the output step of the PBF additive manufacturing process are collected and accumulated, and guiding for optimizing the output step is performed on the basis of the collected and accumulated data, and thus output trial and error can be reduced and output stability of a portion dependent on equipment status can be enhanced.
