MIXED POWDER FOR CUBIC MOLDING, AND CUBIC MOLDED OBJECT
PROBLEM TO BE SOLVED: To provide inexpensive mixed powder for cubic molding having sufficient fluidity and also capable of imparting sufficient strength to a cubic molded object directly after molding, and a cubic molded object.SOLUTION: Provided mixed powder 31 for cubic molding containing a water-soluble organic matter having a water permeation volume of 20 cubic millimeter or lower, hemihydrate gypsum and a gypsum curing promoter, in which the ratio of the gypsum curing promoter is 0.1 to 5 wt% to the whole of the mixed powder 31 for cubic molding, thus the mixed powder 31 for cubic molding has sufficient fluidity, and further, the mixed powder 31 for cubic molding capable of imparting sufficient strength to a cubic molded object 30 directly after molding and whose cost is low can be provided.SELECTED DRAWING: Figure 1
【課題】十分な流動性を有し、かつ、成形直後の立体造形物に十分な強度を付与できる安価な立体造形用混合粉体および立体造形物を提供する。【解決手段】水浸透体積が２０立方ミリメートル以下の水溶性有機物、半水石膏、石膏硬化促進剤を含む立体造形用混合粉体３１であって、石膏硬化促進剤の割合は、立体造形用混合粉体３１全体に対して０．１〜５重量％であることから、立体造形用混合粉体３１が十分な流動性を有するとともに、成形直後の立体造形物３０に十分な強度を付与できるコストが安価な立体造形用混合粉体３１を提供することができる。【選択図】図１
