Method for fabricating solid freeform objects |
摘要 |
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. |
