A materials system, kit, and methods are provided to enable the formation of articles by three dimensional printing. A method includes providing a particulate material comprising a plurality of adjacent particles, the particulate material including an aqueous-insoluble thermoplastic; applying to at least some of the plurality of particles an aqueous fluid binder in an amount sufficient to bond those particles together to define an intermediate article; and immersing the intermediate article in a liquid infiltrant medium to define a final article.

Three dimensional printing material system and method using plasticizer-assisted sintering

A materials system and methods are provided to enable the formation of articles by three dimensional printing. The materials system includes particulate mixtures having a whitening agent and a solid particulate additive comprising an acid, the latter adapted for modifying a cure rate of an infiltrant. The materials system also includes aqueous fluids including optical brightening agents.

Three-dimensional printing material system with improved color, article performance, and ease of use

A materials system and methods are provided to enable the formation of articles by Three Dimensional Printing. The materials system includes a transition metal catalyst that facilitates the reaction of an acrylate-containing binder with a particulate material.

Three dimensional printing material system and method using peroxide cure

A materials system, kit, and methods are provided to enable the formation of articles by three dimensional printing. The kit includes (i) a substantially dry particulate material including an aqueous-insoluble thermoplastic particulate material, plaster, and a water-soluble adhesive; (ii) an aqueous fluid binder, and (iii) an infiltrant.

A materials system and method is provided to enable the formation of articles by three-dimensional printing. The materials system includes thermoplastic particulate filler material that allows the accurate definition of articles that are strong without being brittle.

Thermoplastic powder material system for appearance models from 3D printing systems

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.
