Document Type and Number:
Japanese Patent JP2023144353
Kind Code:
A
Abstract:
To provide a laminated molded object production method capable of easily clogging an opening part with a plug by sintering without requiring a welding operation.SOLUTION: A laminated molded object production method has: a precursor formation step S1 in which a liquid binder is jetted to a powder layer to form a solidified layer, and the sequentially formed solidified layers are then laminated to form a precursor 10 having an opening part 12 in communication with an internal space 11; a plug formation step S2 for forming a plug 20 assemblable to the opening part 12; a powder removing step S3 in which unsolidified powder remaining at the internal space 11 is removed from the opening part 12; a binder coating step S4 in which, after the removal of the unsolidified powder, an outer circumferential wall of the plug 20 is coated with the liquid binder; an assembly step S5 in which the plug 20 is assembled to the opening part 12 so that the outer circumferential wall of the plug 20 is brought into contact with an inner circumferential wall of the opening part 12; and a sintering step S6 for sintering the precursor 10 with the plug 20 assembled into the opening part 12.SELECTED DRAWING: Figure 1
