THREE-DIMENSIONAL SHAPING POWDER, THREE-DIMENSIONAL SHAPING COMPOSITION, MANUFACTURING METHOD OF THREE-DIMENSIONAL SHAPED ARTICLE AND THREE-DIMENSIONAL SHAPED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a three-dimensional shaped article which has excellent mechanical strength and can perform clear color expression, further to provide a manufacturing method of the three-dimensional shaped article which has the excellent mechanical strength and can perform the clear color expression and furthermore to provide three-dimensional shaping powder and a three-dimensional shaping composition capable of being suitably used for manufacturing the three-dimensional shaped article which has the excellent mechanical strength and can perform the clear color expression.SOLUTION: Three-dimensional shaping powder is sequentially laminated on a supporting body 9 so as to form cured portions 3 by an inkjet method together with ink 2 containing binding agent and is used for a method for manufacturing a three-dimensional shaped article 100. The three-dimensional shaping powder is constituted of a plurality of particles. The plurality of particles is porous. When a refractive index of the particles is represented by n1 and a refractive index of a cured product of the binding agent contained in the ink 2 is represented by n2, n1 and n2 satisfy a relation of |n1-n2|≤0.2.
