Abstract: The present invention is directed to a three-dimensional printing system and method, and an article made therefrom. The method of the present invention includes building cross-sectional portions of a three dimensional article, and assembling the individual cross-sectional areas in a layer-wise fashion to form a final article. The individual cross-sectional areas are built using an ink-jet printhead to deliver an aqueous fluid to a particle material that includes a first particulate material, a second particulate material, and a third particulate material, wherein the first and second particulate materials react in the presence of the fluid in a period of time, and the third particulate material reacts in the presence of the fluid to form a solid in a longer period of time.

Abstract: A layer of particulate material (20) is applied on a downwardly movable surface (22) of a container (24), preferably using a counter-roller to minimize disruption of previously formed layers. The layer thickness is preferably 50-75 micrometers and an ink-jet nozzle (28) delivers droplets of an aqueous fluid (26) to a portion (30) of the material in any predetermined two-dimensional pattern, causing a reaction and re-hydration of the plaster. A solid circular layer is formed that becomes a cross-sectional portion of the final article, formed of the assembled portions. An independent claim is included for a method for forming an article.

Abstract: A three-dimensional printing materials system and method can produce both appearance models and small numbers of functional parts in an office environment. The method can include building cross-sectional portions of a three-dimensional article, and assembling the individual cross-sectional areas in a layer-wise fashion to form a final article. The individual cross-sectional areas can be built by using an ink-jet printhead to deliver an aqueous solvent or binder to an adhesive particulate mixture, causing the particles of the mixture to adhere together, and to previous cross-sectional areas. The binder can include at least one of nonaqueous organic monomeric compound, anionically ionizable polymer, cationic polymer, polymer, waterborne colloid, or inorganic solute.
