Title:
THREE-DIMENSIONAL MOLDED OBJECT AND THREE-DIMENSIONAL MOLDING METHOD
Document Type and Number:
Japanese Patent JP2017025386
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a three-dimensional molded object achieving high productivity and precision molding of a fine shape with high accuracy, and to provide a molding method of the three-dimensional molded object.SOLUTION: The three-dimensional molded object is formed by depositing a first monolayer comprising a sintered monolayer obtained by irradiating a sintering target material in which metal powder and a binder are kneaded with energy rays capable of sintering the sintering target material, and then depositing a second monolayer comprising at least the sintered monolayer on the first monolayer. The sintered monolayer is formed by aggregating sintered bodies obtained by irradiating the sintering target material discharged into droplets with the energy rays to sinter. A diameter Ds of the sintered body in a plan view of the sintered body and a distance Ps between centers of the sintered bodies adjoining to each other satisfy 0.5≤Ps/Ds<1.0.SELECTED DRAWING: Figure 1
