US Patent 9227366 Process for fabrication of three-dimensional objects

A fabrication process and apparatus for producing three-dimensional objects (36) by depositing a first polymer layer, printing a first ink layer on to the first polymer layer (34), 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 (36) 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.
