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.

Abstract: Systems and corresponding methods are provided for separation of support structures from near net shape manufactured parts. The system can include a support structure and a non-adhering material. The non-adhering material can be positioned on one or more predetermined exterior-facing surfaces of the support structure. The support system can be dimensioned for receipt within a void space of a porous green body defined by an overhang region of the porous green body. After receipt within a void space of a porous green body that undergoes a thermally-induced volumetric change, the support system can be configured to support the overhang region and the non-adhering material can be configured to inhibit adherence of the exterior-facing surfaces of the support structure to opposed surfaces of the void space.

Abstract: A fabrication process for producing three-dimensional objects and removable support structures. The removal of the support structure from the object is facilitated by the deposition of a release agent or a release layer between the object and the support structure. The removal of the support structure may be further facilitated by applying forced cooling, filament density adjustments, or changes in deposition pressure to the object and/or the support structure during fabrication.
