Abstract: A method includes adding about 5 weight percent to about 25 weight percent of carbon nanotubes to a crystalline or semi-crystalline polymer to form a composite and forming a filament or particles from the composite, the filament or particles having a size suitable for use in additive manufacturing, in the absence of the carbon nanotubes a melt viscosity of the crystalline or semi-crystalline polymer is below 100 Pa·s, preventing its use in additive manufacturing. The filament or particles comprising carbon nanotubes can be used in methods of additive manufacturing.

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.
