|1. (WO2018003832) HYDRAULIC COMPOSITION FOR ADDITIVE MANUFACTURING DEVICE, AND PROCESS FOR PRODUCING CASTING MOLD|
|Applicants:||TAIHEIYO CEMENT CORPORATION
|Title:||HYDRAULIC COMPOSITION FOR ADDITIVE MANUFACTURING DEVICE, AND PROCESS FOR PRODUCING CASTING MOLD|
The present invention has solved the problems of conventional shaping materials, and provides a hydraulic composition for additive manufacturing devices which has high strength-developing properties, in particular, early-stage strength-developing properties, and is less apt to cause gas defects or defects due to graphite spheroidizing failures. Specifically, the hydraulic composition for additive manufacturing devices of the present invention at least contains calcium aluminate. It is preferable that the hydraulic composition contain 0.5-10 parts by mass of gypsum per 100 parts by mass of the calcium aluminate.
