    Abstract: A method is disclosed. The method may comprise forming an image on a surface by controlled electrostatic transfer of a fluid print agent comprising thermoplastic resin disposed in a carrier fluid. The method may also comprise heating the fluid print agent on the surface to remove the carrier fluid and to melt the thermoplastic resin and allowing the melted thermoplastic resin in continuous areas on the surface to fuse together to form an image from fused print agent. The method may further involve providing a printed substrate bearing the image formed from fused print agent. The method may further comprise irradiating the printed substrate with an ultraviolet narrowband source so as to cause heating of the fused print agent to melt the thermoplastic resin. A print system and a print apparatus are also disclosed.

    Abstract: Dye-sublimation printers and methods are disclosed for porous substrates or for polyester-coated substrates. In an example the device comprises a substrate path, a printhead, over a print zone of the substrate path, to transfer a print fluid on the substrate; a narrow band radiation source, over a sublimation zone of the substrate path to sublimate a portion of the transferred print fluid to form an image on the substrate; and an advancing mechanism, to transfer the substrate from the print zone to the sublimation zone.

    Abstract: An example of an additive manufacturing system is disclosed. The example disclosed herein comprises a build material distributor, a preheating source, and a controller. The build material distributor is to form build material layers from an intended build material having a color. The preheating source is to emit energy at a wavelength related to the intended build material color so that at least a 40% of the energy is absorbed by the build material. The controller is to receive printing instructions to print a 3D object, wherein the printing instructions define an area to be fused in a build material layer. The controller is also to instruct the build material distributor to form the build material layer. The controller is further to control the preheating source to emit energy to preheat a zone comprising the area to be fused.

    Abstract: According to one example, there is provided a method of additive manufacturing that comprises obtaining data relating to a 3D object to be manufactured, forming a layer of build material on a build platform, applying a cooling agent in a pattern surrounding a portion of build material to be solidified, and applying energy only to the build material on which cooling agent is applied and to the surrounded portion of build material such that the surrounded portion of build material heats up sufficiently to coalesces, and such that build material on which cooling agent is applied is cooled by the cooling agent and is prevented from heating up sufficiently to coalesce.

    Abstract: One example of a display device includes an electronic paper display, a counter-electrode, a floating electrode, and a patterned layer. The electronic paper display is imageable by receiving charges on an imaging surface of the electronic paper display. The counter-electrode is opposite to the imaging surface of the electronic paper display. The floating electrode is capacitively coupled to the counter-electrode. The patterned layer on the floating electrode provides mechanical protection for the floating electrode while enabling an air discharge to the floating electrode.
