Abstract
A method for fabricating a colored 3D object is provided. The method includes: forming, based on layer-structure data of a target object, a layer-structure product by printing of a molding material; forming a layer-print product by printing color inks on the layer-structure product based on layer-color data; and repeatedly forming the layer-print product to provide a plurality of the layer-print products, and fabricating a colored 3D object from the plurality of the layer-print products, stacked one over another. The color inks are printed synchronously or following the formation of the layer-structure product. A system for fabricating a colored 3D object includes a processing terminal, a print head, and a drive controller. The method and system improve a dimensional accuracy and printing efficiency of the colored 3D object.
