    • The present invention is drawn toward materials, methods and systems for solid free-form fabrication of three dimensional objects. In one embodiment, a method for solid free-form fabrication of a three-dimensional object can comprise steps of a) depositing a particulate composition including inorganic phosphate particulates in a defined region; b) ink-jetting an aqueous liquid onto a predetermined area of the particulate composition to form hydrated cement in the predetermined area; c) hardening the hydrated cement; and repeating steps a) through c) such that multiple layers of the cement are formed that are bound to one another, thereby forming the three dimensional object. In another embodiment, a system for solid free-form fabrication of three-dimensional objects can comprise a particulate composition including inorganic phosphate particulates; a substrate configured for supporting at least a layer of the particulate composition in a defined region; and an ink-jettable aqueous liquid configured for being jetted in the defined region to hydrate at least a portion of the particulate composition to form a cement.
    • 本发明涉及用于固体自由形成三维物体的材料,方法和系统。 在一个实施方案中,用于固体自由形成三维物体的方法可以包括以下步骤:a)在限定区域内沉积包含无机磷酸盐颗粒的颗粒组合物; b)将水性液体喷墨到所述颗粒组合物的预定区域上以在所述预定区域中形成水合水泥; c)硬化水合水泥; 并且重复步骤a)至c),使得形成彼此结合的多层水泥,从而形成三维物体。 在另一个实施方案中,用于固体自由形成三维物体的系统可以包括包含无机磷酸盐颗粒的颗粒组合物; 衬底,其被配置为在确定的区域中至少支撑所述颗粒组合物层; 以及喷墨水性液体,其被配置为在所述限定区域中喷射以使至少一部分所述颗粒组合物水合以形成水泥。
