Abstract: Disclosed herein is a printing method and system for forming a three dimensional article. The method includes depositing a UV curable composition and applying UV radiation to cure the UV curable composition to form a 3D structure. The method includes depositing a conductive metal ink composition on a surface of the 3D structure and annealing the conductive metal ink composition at a temperature of less than the glass transition temperature of the UV curable composition to form a conductive trace on the 3D structure. The method includes depositing a second curable composition over the conductive trace; and curing second curable composition to form the 3D printed article having the conductive trace embedded therein.

Abstract: An ink composition useful for digital offset printing applications includes a colorant and a high viscosity thickening agent. A process for variable data lithographic printing includes applying a dampening fluid to an imaging member surface; forming a latent image by evaporating the dampening fluid from selective locations on the imaging member surface to form hydrophobic non-image areas and hydrophilic image areas; developing the latent image by applying an ink composition comprising an ink component to the hydrophilic image areas, the ink composition comprising a high viscosity thickening agent to raise the viscosity of the composition from about 1.05 to about 2 times higher while maintaining excellent transfer to a substrate at low temperatures.

Abstract: An ink composition useful for digital offset printing applications includes a colorant and a high viscosity thickening agent. The ink is formulated to incorporate a gellant into the ink set to help meet the requirement of two different viscosity or temperature pairs at two different stages of the ink delivery process. In lithography imaging a bulk ink is first transferred onto an anilox roll and then onto the imaging cylinder blanket. The first transfer from bulk ink to anilox roll requires the ink to have a low viscosity while the transfer from roll to imaging blanket requires a high viscosity. The addition of the gellant will increase the viscosity difference within the allowable temperature range thus increasing process latitude and robustness.
