Abstract: Layers of build and support material on an intermediate transfer surface are exposed to a solvent using a solvent application station to make the build material tacky, without affecting the support material. Then, the intermediate transfer surface moves past a transfuse station (the transfuse station is positioned to receive the layers after exposure to the solvent) and a platen moves relative to the intermediate transfer surface to contact the platen to one of the layers on the intermediate transfer surface. The intermediate transfer surface transfers a layer of the build material and the support material to the platen each time the platen contacts the layers on the intermediate transfer surface at the transfuse station to successively form a freestanding stack of the layers of build and support material on the platen.

Abstract: A three-dimensional (3-D) printer includes build and support material development stations positioned to transfer layers of build and support materials to an intermediate transfer surface. The intermediate transfer surface transfers a layer of the build and support materials to a platen each time the platen contacts the intermediate transfer surface. A sensor detects the thickness of the layer on the platen, and a mechanical planer is positioned to contact and level the layer on the platen as the platen moves past the mechanical planer. Additionally, a feedback loop is electrically connected to the sensor and the mechanical planer. The mechanical planer adjusts the amount of the build material and the support material removed from the layer based on the thickness of the layer on the platen, as determined by the sensor.

Abstract: An apparatus and method for printing directly onto print media including smooth non-absorbent media substrates (e.g., polymer films) inks having a wide range in viscosity, so that flexographic, gravure, and lithographic inks can all be contemplated. The proposed method is able to print with variable data/imaging. Dampening fluid may be patterned onto an imaging roll by coating the imaging roll with a layer of the dampening fluid and selectively evaporating off a patterned portion via a laser imaging device. The imaging roll then contacts the print substrate and transfers the patterned dampening fluid onto the substrate via film splitting. The substrate then passes through an inker station where ink is deposited directly to the substrate for attachment thereto except where rejected by the dampening fluid.

Abstract: A UV printed transferrable material and a method for producing the same are disclosed. For example, the UV printed transferrable material includes a first liner, a UV ink layer on top of the first liner in a desired image, a primer layer on top of the UV ink layer, wherein the UV ink layer and the primer layer are cured, and a second liner on top of the primer layer.

Abstract: A system for printing on a multi-dimensional object includes a plurality of print heads, a mounting structure configured to receive an integrated object packaging and holder for an object and to movably mount on a support member, an actuator configured to move the mounting structure along the support member, and a processing device. The system also includes a a non-transitory, computer-readable memory containing programming instructions that are configured to cause the processing device to control a movement of the mounting structure relative to the plurality of print heads, and operate the plurality of print heads to eject marking material onto an object mounted on the mounting structure.

Abstract: A system and method are provided for depositing a uniform layer of a dampening solution using a vapor deposition/condensation process or technique on a reimageable surface in an image forming device using a proposed variable data digital lithographic image forming architecture that transfers ink at an efficiency rate in excess of 95 percent. A reimageable surface is configured of a low surface energy surface component that directly accepts a vaporized dampening solution having a lower surface energy than the surface energy of the reimageable surface. A uniformity in the layer of condensed dampening solution on the reimageable surface is a product of the relative difference in the low surface energy of the reimageable surface and the lower surface energy of the dampening solution.

Abstract: A method of forming a lenticle on a substrate includes operating a plurality of inkjets to eject a plurality of ink drops of an optically transparent ink onto a surface of a substrate between a first printed line of an optically opaque ink and a second printed line of the optically opaque ink to form a lenticle from the optically transparent ink, the first printed line being formed substantially parallel to the second printed line with a separation between the first printed line and the second printed line corresponding to a predetermined width of a lenticle to be formed on the substrate.

Abstract: A 3-D printer includes build and support material development stations that electrostatically transfer build material and support material to an ITB. The ITB transfers a layer of build and support material to a platen each time the platen contacts one of the layers on the ITB, to successively form a freestanding stack of the layers on the platen. A sensor is positioned to generate a topographic measurement of the layer on the platen, and an aerosol applicator is positioned to propel build and support material on to the layer on the platen. The aerosol applicator controls the build and support material being propelled, based on the topographic measurement from the sensor through a feedback loop, to adjust the amount and location of the build material and the support material propelled on to the layer, and thereby control the flatness of surface topology of the layers in the freestanding stack on the platen.

Abstract: A 3-D printer includes a development station positioned to electrostatically transfer layers of material to an intermediate transfer surface, and a transfer station adjacent the intermediate transfer surface. The transfer station is positioned to receive the layers as the intermediate transfer surface moves past the transfer station. Also, a platen is included that moves relative to the intermediate transfer surface. The intermediate transfer surface transfers a layer of the material to the platen each time the platen contacts one of the layers on the intermediate transfer surface at the transfer station to successively form a freestanding stack of the layers on the platen. A fusing station is positioned to apply light to each layer, after each layer is transferred from the transfer station to the platen. The fusing station selectively applies the light to sinter a portion of the material within the layer.
