THREE-DIMENSIONAL MOLDING MATERIAL SET, METHOD FOR MANUFACTURING THREE-DIMENSIONAL MOLDED OBJECT, AND THREE-DIMENSIONAL MOLDED OBJECT

摘要

PROBLEM TO BE SOLVED: To provide a three-dimensional molding material set from which a three-dimensional molding object using a material with a high melting point and high hardness and having a complicated three-dimensional shape can be easily, efficiently and fast manufactured with high strength.SOLUTION: The three-dimensional molding material set includes at least: a powder material for three-dimensional molding, which contains granular particles having a volume average particle diameter of 10 to 70 μm and comprising a resin and inorganic particles having a volume average particle diameter of 1 μm or less in the primary particles; and a liquid material for three-dimensional molding, which contains an amino group-containing compound. The three-dimensional molding material set is an aqueous solution, in which the above amino group-containing compound contains a metal; the metal is titanium or zirconium; and the amino group-containing compound is polyethylene imine having a weight average molecular weight of 10,000 or more and is included by 3 to 20 mass%.SELECTED DRAWING: None
