Abstract: In an example implementation, a method of printing a three-dimensional (3D) object includes, applying a layer of build powder onto a printing platform and depositing a deliberate micropattern of liquid agent onto the powder within a macropattern that defines a cross-section of a 3D object to be printed. The method includes forming a microstructure from the deliberate micropattern by applying fusing energy to the powder, the microstructure comprising fused areas and sintered areas between the fused areas.

Abstract: An apparatus and method for generating a three-dimensional object. The apparatus includes a build material area, at least one agent distributor with a fluid reservoir to store fluid agent and at least one fluid ejection die to selectively eject fluid agent in the build material area. A cooling system to remove heat from the at least one fluid ejection die has a heat sink. The at least one fluid ejection die is in thermal contact with the heat sink via the fluid agent of the fluid reservoir.

Abstract: A printing method includes selecting an inkjet ink including a dye, and selecting an active agent, including an electromagnetic radiation-absorbing active material, and an aqueous or non-aqueous vehicle. The method further includes inkjet printing the dye sublimation inkjet ink and the active agent directly onto a textile fabric. The textile fabric having the ink and active agent thereon is exposed to electromagnetic radiation.

Abstract: In one example, a container includes a rigid hollow core, a bag in the core to hold a printing fluid, and a plug plugging one end of the core. The plug includes a flange covering the edge of the end of the core, a part protruding from the flange into and plugging the end of the core, and a port operatively connected to an outlet from the bag such that printing fluid can flow out of the bag and through the port.

Abstract: In an example of a three-dimensional printing method, a polymeric build material is applied. A fusing agent is selectively applied on at least a portion of the polymeric build material. The fusing agent includes cesium tungsten oxide nanoparticles, a zwitterionic stabilizer, and an aqueous vehicle. The polymeric build material is exposed to electromagnetic radiation to fuse the portion of the polymeric build material in contact with the fusing agent to form a layer.
