Title:
GRANULAR MATERIAL, METHOD FOR MANUFACTURING GRANULAR MATERIAL, DEVICE FOR MANUFACTURING MOLD BY ADDITIVE MANUFACTURING, AND METHOD FOR MANUFACTURING MOLD BY ADDITIVE MANUFACTURING
Document Type and Number:
WIPO Patent Application WO/2017/183134
Kind Code:
A1
Abstract:
The present invention provides a granular material that can be excellently coated regardless of the type of granular material and can be used without regenerating a refractory aggregate of a non-printed portion in manufacturing a mold by additive manufacturing. The granular material is a granular material for use in manufacturing a mold by additive manufacturing, wherein a coating material in which acid is mixed in or coated for a catalyst that activates and cures an organic binder for bonding the granular material contains material that can form a hydration reaction having a moisture absorbing function and that exhibits a catalytic effect.
