A fabrication process and apparatus for producing three-dimensional objects by depositing a first polymer layer, printing a first ink layer on to the first polymer layer, depositing a second polymer layer on to the first ink layer, and printing a second ink layer on to the second polymer layer. The deposition and printing steps may be repeated until a three-dimensional object is formed. The inks used to form at least one of the first and second ink layers may include dyes or pigments so that the three-dimensional object may be a colored three-dimensional object.

Process and apparatus for fabrication of three-dimensional objects

A fabrication process and apparatus for producing three-dimensional objects () by depositing a first polymer layer, printing a first ink layer on to the first polymer layer (), depositing a second polymer layer on to the first ink layer, and printing a second ink layer on to the second polymer layer. The deposition and printing steps may be repeated until a three-dimensional object () is formed. The inks used to form at least one of the first and second ink layers may include dyes or pigments so that the three-dimensional object may be a colored three-dimensional object.

Process for fabrication of three-dimensional objects

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, 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.
