Title:
POWDER MATERIAL FOR THREE-DIMENSIONAL MOLDING, HARDENING LIQUID, THREE-DIMENSIONAL MOLDING KIT, AND METHOD AND APPARATUS FOR MANUFACTURING THREE-DIMENSIONAL MOLDED ARTICLE
Document Type and Number:
Japanese Patent JP2019167623
Kind Code:
A
Abstract:
To provide a method for manufacturing a three-dimensional molded article, by which a three-dimensional molded article having a complex shape can be easily and efficiently manufactured by using a powder material of metal or the like without causing a shape collapse before sintering or the like and with high dimensional accuracy.SOLUTION: The method for manufacturing a three-dimensional molded article aims to manufacture a three-dimensional molded article by at least repeating: a powder material layer formation step of forming a powder material layer using a powder material for three-dimensional molding, which comprises an organic material and a base material that does not react with a hardening liquid; and a hardening liquid imparting step of imparting a hardening liquid containing a crosslinking agent that crosslinks with the organic material to the powder material layer formed in the powder material layer formation step.SELECTED DRAWING: Figure 1
