GRANULAR MATERIAL, 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 granular material capable of being used for efficiently manufacturing a three-dimensional shaped article excellent in dimensional accuracy, mechanical strength and durability, a three-dimensional shaping composition capable of being used for efficiently manufacturing the three-dimensional shaped article excellent in the dimensional accuracy, the mechanical strength and the durability, a manufacturing method of the three-dimensional shaped article capable of manufacturing the three-dimensional shaped article excellent in the dimensional accuracy, the mechanical strength and the durability and the three-dimensional shaped article excellent in the dimensional accuracy, the mechanical strength and the durability.;SOLUTION: A three-dimensional shaping composition is used for manufacturing a three-dimensional shaped article manufactured by repeatedly forming and laminating layers and contains a granular material configured so as to be shrinkable. It is preferable that the granular material irreversibly shrinks. Further, it is preferable that the granular material shrinks by heat.;COPYRIGHT: (C)2015,JPO&INPIT
