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.

Abstract: An example of a dispersion includes cesium tungsten oxide nanoparticles, a zwitterionic stabilizer, and a balance of water. An example of a jettable composition includes cesium tungsten oxide nanoparticles, a zwitterionic stabilizer, a surfactant, a co-solvent, and a balance of water. A method for improving the stabilization of a jettable composition includes incorporating a zwitterionic stabilizer in the jettable composition, which includes the cesium tungsten oxide nanoparticles, the surfactant, the co-solvent, and the balance of water.

Abstract: A multi-fluid kit for three-dimensional printing can include a fusing agent and a coloring agent. The fusing agent can include an electromagnetic radiation absorber in a first liquid vehicle. The electromagnetic radiation absorber can absorb radiation energy and can convert the radiation energy to heat. The coloring agent can include a magenta rhodamine dye and a fluorescence quenching iodide salt in a second liquid vehicle. A molar ratio of the magenta rhodamine dye to the fluorescence quenching iodide salt can range from about 1:1 to about 1:10.

Abstract: A method includes applying a nominal back pressure to a fluid ejection assembly and nozzles to form a first amount of back pressure therein by a back pressure regulator. The method also includes applying a first pressure to lower the first amount of back pressure within the fluid ejection assembly and the nozzles to form a second amount of back pressure therein by a pressurization module in response to an activation of a cleaning operation. The method also includes moving at least one of the fluid ejection assembly and a wicking member against each other to perform the cleaning operation. The wicking member moves relative to the fluid ejection assembly against and across the nozzle surface to transfer fluid residue from at least one of the nozzle surface and the nozzles to a portion of the wicking member to form a used wicking member portion.
Abstract translation: 一种方法包括将标称背压施加到流体喷射组件和喷嘴以通过背压调节器在其中形成第一量的背压。 该方法还包括施加第一压力以降低流体喷射组件和喷嘴内的第一量的背压，以响应于清洁操作的激活，通过加压模块在其中形成第二数量的背压。 该方法还包括将流体喷射组件和芯吸构件中的至少一个彼此移动以执行清洁操作。 芯吸构件相对于流体喷射组件移动并抵靠喷嘴表面，以将来自喷嘴表面和喷嘴中的至少一个的流体残余物传送到芯吸构件的一部分以形成使用的芯吸构件部分。

Abstract: A three-dimensional printing kit, as presented herein, can include a particulate build material and a binder agent. The particulate build material can include from about 80 wt % to 100 wt % metal particles based on the total weight of the particulate build material. The binder agent can include an aqueous liquid vehicle, an acrylic polymer or copolymer latex dispersion, a sulfonated small-molecule dispersed pigment, and a solubilized dihydrazide. A sulfonated small-molecule of the sulfonated small-molecule dispersed pigment can be from about 100 g/mol to about 2000 g/mol. The binder agent can exclude a polymeric dispersant.
