Abstract
The present invention provides a system capable of estimating a molding state in a manufacturing process of the lamination molded object. According to the present invention, provided is a system for estimating a molding state in a manufacturing process of the lamination molded object including an image acquisition unit and an analysis unit. The lamination molded object is manufactured by repeating a material layer forming step of forming a material layer by supplying material powder onto a molding region and a solidified layer forming step of forming a solidified layer by irradiating the material layer with a laser beam. The image acquisition unit is configured to acquire image data of a spatter generated around a molten pool formed by irradiation with the laser beam. The analysis unit is configured to analyze the image data to estimate a parameter representing the molding state.
