MOLDING METHOD OF MOLDED OBJECT
To provide a molding method of a molded object, which can prevent blockage due to curing of a hydraulic composition in an additive manufacturing device and ensure self-reliance until the hydraulic composition is cured.SOLUTION: A molding method of a molded object using a hydraulic composition for an additive manufacturing device includes: a cement composition preparing step of mixing cement with a ferrite phase ratio of 4.0 mass% or more as a value calculated by Borg's formula and water to obtain a cement composition 8; an accelerating agent supplying step of supplying an accelerating agent 9 in an amount of 0.2 to 5.0 pts.mass per 100 pts.mass of cement to the cement composition 8 in a nozzle 3 of an additive manufacturing device 1, immediately before extruding the cement composition 8; an extruding step of extruding the hydraulic composition 11 for the additive manufacturing device from the additive manufacturing device 1; a molding step of molding a molded object by using the extruded hydraulic composition 11 for the additive manufacturing device.SELECTED DRAWING: Figure 1
【課題】付加製造装置内での水硬性組成物の硬化による閉塞を防ぎ、かつ、水硬性組成物が硬化するまでの自立性を確保することができる造形物の造形方法を提供する。【解決手段】付加製造装置用水硬性組成物を用いた、造形物の造形方法であって、ボーグの式で算出される値としてフェライト相の割合が４．０質量％以上であるセメント、及び、水を混合して、セメント組成物８を得るセメント組成物調製工程と、セメント組成物８を押し出す直前に、付加製造装置１のノズル３内のセメント組成物８に、セメント１００質量部に対して０．２～５．０質量部となる量の急結剤９を供給して、付加製造装置用水硬性組成物を得る急結剤供給工程と、付加製造装置用水硬性組成物１１を付加製造装置１から押し出す押し出し工程と、押し出した付加製造装置用水硬性組成物１１を用いて、造形物を造形する造形工程とを含む造形物の造形方法。【選択図】図１
