POLYMER FILAMENTS COMPRISING AN AQUEOUS-SOLUBLE IMIDE POLYMER AND USE THEREOF AS A SACRIFICIAL PRINTING MATERIAL IN ADDITIVE MANUFACTURING

Номер: US20220064462A1
Автор: Kimberly D. Nosella, Richard Philip Nelson Veregin, Naveen Chopra
Принадлежит: Xerox Corporation

When making parts by additive manufacturing, particularly by fused filament fabrication, it is sometimes necessary to include a removable support during part fabrication due to the shape of the part. An overhang, for instance, may be fabricated using a support structure, which is subsequently eliminated following polymer matrix consolidation. Elimination of a removable support following part fabrication may be problematic in some instances. Polymer filaments suitable for forming removable supports during additive manufacturing may comprise at least one imide polymer having at least partial solubility in aqueous fluids. Imide polymers may include, for example, polyimides and polyesterimides. Additive manufacturing processes may comprise forming a supported part by depositing a build material and a removable support comprising an imide polymer, wherein at least a portion of the build material is deposited upon the removable support. An unsupported part may be formed following exposure of the supported part to an aqueous fluid.

A phase change ink includes an ink vehicle that includes at least one curable carrier, at least one gellant, at least one wax and at least one alkoxysilane monomer. In a method of forming an image with the ink, the phase change ink is melted, then jetted onto an image receiving substrate, wherein the phase change ink forms a gel state, and exposed to ultraviolet light to cure the curable components of the phase change ink. The alkoxysilane participates in crosslinking to form silicon-oxygen-silicon bonds, thereby producing an ink with advantageous stability and high image quality.

Systems and methods are provided for digital printing of Braille or other raised printing. In some embodiments, ink is printed directly from a print head onto a substrate, rather than onto a transfer drum that is later printed onto a substrate. In some embodiments, a plurality of layers of a curable, phase-change ink are printed onto the substrate, wherein pauses of a predetermined time are included in between of layers to enable the curable, phase-change ink to set up into a given shape and height. In some embodiments, temperatures of printing components are lowered from those used for traditional printing, so as to enable the curable phase change ink to set up into a given shape and height. In some embodiments, spacing of components are altered from those used for traditional printing, so as to enable the curable phase change ink to set up into a given shape and height. 1. A method for digital raised printing comprising:placing a substrate onto a substrate engaging surface;sequentially applying a plurality of layers of a curable phase-change ink from a print head onto the substrate, wherein a predetermined period of time elapses between the application of each layer; andcuring the plurality of layers of ink on the substrate.2.

Protective layer for reimageable medium

Номер: US20070003847A1
Автор: Naveen Chopra, Gabriel Iftime, Peter Kazmaier
Принадлежит: XEROX CORPORATION

A reimageable recording medium includes a substrate, a display layer, and a protective layer. The protective layer comprises a microencapsulated diarylethene material that is capable of switching between a UV absorbing and UV transparent state. During an imaging process, the protective layer is switched from a UV absorbing state to a UV transparent state to allow UV light of a sufficient wavelength to convert a photochromic material of the display layer to a colored state to form an image. The protective material is then switched back to a UV absorbing state to prevent the UV light component from a reading source to convert unimaged areas of the display layer to change color, which would reduce the contrast and resolution of the imaged medium.

When constructing parts by additive manufacturing, it is sometimes necessary to include a support structure during part fabrication, wherein the support structure is subsequently removable. Polymer filaments suitable for forming support structures during additive manufacturing may comprise a polymeric material, and a gas-forming substance admixed with the polymeric material in an effective amount to undergo effervescence when the polymeric material is in contact with at least one fluid comprising a liquid phase. Additive manufacturing processes may comprise forming a supported part by depositing a build material and a removable support (e.g., upon a print bed) formed from such polymer filaments, wherein at least a portion of the build material is deposited upon the removable support. Exposure of the gas-forming substance to a fluid in which the polymeric material dissolves or degrades may promote gas formation to facilitate elimination of the removable support by effervescence.

At the jet operating temperature, droplets of liquid ink are ejected from the printing device and, when the ink droplets contact the surface of the recording substrate, either directly or via an intermediate heated transfer belt or drum, they quickly solidify to form a predetermined pattern of solidified ink drops. Phase change inks have also been used in other printing technologies, such as gravure printing.Phase change inks for color printing typically comprise a phase change ink carrier composition which is combined with a phase change ink compatible colorant.

Phase-change digital advanced lithographic imaging inks with amide gellant transfer additives

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.
