Title:
METHOD FOR MANUFACTURING THREE-DIMENSIONALLY SHAPED MOLDING
Document Type and Number:
Japanese Patent JP2021138976
Kind Code:
A
Abstract:
To provide a method for manufacturing a three-dimensionally shaped molding having a ventilation part capable of favorably ventilating with the outside.SOLUTION: A method for manufacturing a three-dimensionally shaped molding comprises alternately and repeatedly laminating powder layers and solidified layers by performing a process (i) of irradiating a prescribed portion of a powder layer with light beam L and sintering or melting and solidifying powder in the prescribed portion so as to form a solidified layer, and a process (ii) of forming a new powder layer on the obtained solidified layer and irradiating the prescribed portion of the new powder layer with light beam to form a further solidified layer. Specifically, the method manufactures the three-dimensionally shaped molding having a high-density part and a low-density part, uses at least part of the low density part as a ventilation part, and re-irradiates an edge part forming a hole area at least composing part of the ventilation part with the light beam during or after formation of the solidified layer by irradiation of the light beam.SELECTED DRAWING: Figure 4
