Abstract: A process including providing a curable gellant ink composition having a phase transition temperature; heating the ink composition to a temperature above the phase transition temperature; depositing the ink composition onto a substrate; wherein upon contact with the substrate the ink composition freezes to provide a gel ink layer; treating at least a portion of the gel ink layer whereby treated gellant ink reacts to form a three-dimensional object and wherein untreated gellant ink does not react and remains in gellant form; optionally, wherein the unreacted gellant ink provides a support structure for overhang portions of the three-dimensional object.

Abstract: A support material for use in additive manufacturing includes greater than about 30 weight percent up to about 70 weight percent of a C12 to C18 fatty alcohol ethoxylate, about 30 weight percent to about 70 weight percent of a C16 to C22 fatty alcohol, and a tackifier, a transition temperature measured as the temperature immediately before phase change, based on viscosity measurement, is less than about 65° C. A system for additive manufacturing includes such a support material and a build material, the ratio of C12 to C18 fatty alcohol ethoxylate to C16 to C22 fatty alcohol is selected for property matching of the support material to the build material. A method of additive manufacturing includes providing such a system and printing via an inkjet printer the support material and the build material to provide a precursor to a three-dimensional printed article.

Abstract: This disclosure is directed to formulations for inks and methods for achieving those formulations for use in an emerging class of variable data digital lithographic image forming devices. Specific sub-system requirements that are unique to the emerging architecture caused an exploration of formula boundaries that, through experimentation, were determined to substantially reduce particle sizes for the color pigments enabling a higher latitude for ink image thickness. Experimentally-derived behavior in reducing particle size and adjusting rheological properties results when a inks are processed using a 3-roll mill with cooling employed. Inks demonstrated a preferably reduced preferred particle size distribution enabling a higher latitude for ink image thickness down to about 0.5 microns. Improved rheological profiles allow the inks to have higher zero-shear or static viscosity to be less runny and to allow more consistent flow into and through ink loaders and Anilox systems to a reimageable surface of an imaging member.

Abstract: A method for ink-based digital printing includes applying a uniform layer of dampening fluid to a surface of an imaging member; laser patterning the dampening fluid layer by selectively removing portions of the dampening fluid according to digital image data; and inking the laser-patterned dampening fluid layer on the imaging member surface with a aqueous heterogeneous ink to form an ink image, wherein the aqueous heterogeneous ink self-coalesces before the ink is transferred from the imaging member surface.
