Abstract
The present invention is drawn toward materials, methods and systems for solid free-form fabrication of three dimensional objects. In one embodiment, a method can comprise a) applying a particulate blend in a layer, wherein the particulate blend includes calcium aluminate particulates and polymeric binder particulates; b) dispensing an aqueous polyol-containing liquid vehicle onto a predetermined area of the particulate blend to form hydrated cement in the predetermined area; c) hardening the hydrated cement; and d) 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.
