Title:
ADDITIVE FABRICATION CONDITION SEARCH DEVICE AND ADDITIVE FABRICATION CONDITION SEARCH METHOD
Document Type and Number:
WIPO Patent Application WO/2023/127321
Kind Code:
A1
Abstract:
The present invention improves the efficiency in searching for an optimum solution for additive fabrication conditions of an additive fabrication device. This additive fabrication condition search device (2) comprises: a defect database in which materials, shape information, additive fabrication conditions, monitoring information during fabrication, and defect information are accumulated in association with one another; a first machine learning unit (47) which outputs additive fabrication conditions corresponding to material information and device information and outputs new additive fabrication conditions from among multiple combinations of additive fabrication conditions and defect information; an identification unit (43) which acquires monitoring information during fabrication by causing the additive fabrication device to carry out the fabrication using the additive fabrication conditions and acquires shape information and defect information by inspecting a fabricated object; a second machine learning unit (48) which uses a model, which has been learned by using the defect database as training data, to estimate the defect information of the fabricated object from the monitoring information and stores the estimated defect information into the defect database; and a determination unit (44) which determines whether or not the defect information of the fabricated object has achieved an evaluation target value.
