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.
What is claimed is: 1. A method for forming a solid object by three-dimensional printing, the method comprising the steps of: providing a chemical composition comprising a solvent including a nonaqueous organic monomeric compound selected from the group consisting of a silane, a vinyl monomer, an a
What is claimed is: 1. A method for forming a solid object by three-dimensional printing, the method comprising the steps of: providing a chemical composition comprising a solvent including a nonaqueous organic monomeric compound selected from the group consisting of a silane, a vinyl monomer, an acrylic monomer, a methacrylate monomer, and combinations thereof; and depositing the chemical composition through a piezoelectric printhead onto a particulate material, wherein the chemical composition selectively adheres the particulate material to form the solid object. 2. A method for forming a solid object by three-dimensional printing, the method comprising the steps of: providing a chemical composition comprising a solvent; and depositing the chemical composition through an electromechanical printhead onto a particulate material, wherein the chemical composition selectively adheres the particulate material to form the solid object and the solvent comprises a mixed vinyl-silane monomer. 3. The method of claim 1, wherein the solvent is curable by ultraviolet radiation, in combination with a photoinitiator, to form the solid object. 4. The method of claim 1, wherein the particulate material comprises a resin and the composition comprises a solvent for the resin. 5. The method of claim 1, wherein the particulate material comprises a filler. 6. The method of claim 5, wherein the particulate material comprises a printing aid. 7. A method for forming a solid object by three-dimensional printing, the method comprising the steps of: providing a chemical composition comprising: an adhesive; and a fluid; and depositing the chemical composition through a piezoelectric printhead onto a particulate material wherein the chemical composition selectively adheres the particulate material to form the solid object and the adhesive comprises an inorganic solute selected from the group consisting of sodium silicate, sodium polyphosphate, sodium hydrogen phosphate, sodium hydrogen pyrophosphate, sodium tetraborate, ammonium hydrogen phosphate, sodium chloride, ammonium nitrate, potassium sulfate, ammonium chloride, calcium formate, and combinations thereof.
