Abstract: A fabrication process and method for producing grayscale or full color three-dimensional objects by depositing a first part material layer, printing a first colorization layer on to the first part material layer, depositing a second part material layer on to the first colorization layer, and printing a second colorization layer on to the second part material layer. The part material deposition and coloring agent deposition operations may be repeated until a three-dimensional colored object is formed. The colorization inks used to form at least one of the first and second colorization layers allow the creation of grayscale or full color 3D printed parts. The process facilitates deposition of colorization agents on a part material to produce full color parts, improves color gamut and resolution, allows creation of hidden features within parts (e.g., wear indicators), and enhances aesthetics and functionality of three-dimensional objects with the use of color.
