Title:
METHOD AND APPARATUS FOR THREE-DIMENSIONAL MANUFACTURING
Document Type and Number:
Japanese Patent JP2023039032
Kind Code:
A
Abstract:
To provide a method for three-dimensional manufacturing that can ensure that a manufactured object has a desired manufacturing quality.SOLUTION: A method for three-dimensional manufacturing comprises a first preparation step that acquires a moving picture m including an irradiation point of an energy beam by taking pictures on a plate 51 while emitting an energy beam onto the plate 51, according to a beam-irradiation setting including a heat-input setting indicative of an allowable range of a parameter defining a heat input to be given to a powder material P by an energy beam and locus information defining an irradiation position of the energy beam, a second preparation step that acquires a measurement result of the parameter defining the heat input by analyzing the moving picture m, a third preparation step that determines whether or not the measurement result is included in the allowable range, and a manufacturing step that forms a manufactured object PA by irradiating, while uniformly laying a powder material P over the plate 51, the uniformly-laid powder material P with an energy beam.SELECTED DRAWING: Figure 1
