Abstract: The present disclosure is drawn to coalescent inks and material sets, such as for 3D printing. In one example, the coalescent ink can include a conjugated polymer, a colorant imparting a visible color to the coalescent ink, and an ink vehicle comprising a high boiling point co-solvent having a boiling point of 250° C. or greater. The high boiling point co-solvent can be present in an amount from about 1 wt % to about 4 wt % with respect to the coalescent ink.

Abstract: A three-dimensional printing kit can include a build material with from about 80 wt % to 100 wt % polymeric particles having a D50 particle size from about 10 μm to about 150 μm, and a fusing agent including from about 0.5 wt % to about 20 wt % avobenzone particles dispersed in an aqueous liquid vehicle based on a total weight of the fusing agent.

Abstract: In an example of a method for forming three-dimensional (3D) printed electronics, a build material is applied. A fusing agent is selectively applied on at least a portion of the build material. The build material is exposed to radiation and the portion of the build material in contact with the fusing agent fuses to form a layer. An electronic agent is selectively applied on at least a portion of the layer, which imparts an electronic property to the at least the portion of the layer.

Abstract: In one example in accordance with the present disclosure, an additive manufacturing system is described. The additive manufacturing system includes a build material distributor to deposit metal powder build material and an agent distribution system to selectively deposit a binding agent on the metal powder build material in a pattern of a layer of a three-dimensional (3D) object to be printed. The additive manufacturing system also includes an ultraviolet (UV) energy source. The UV energy source, in a layer-by-layer fashion 1) cures the binding agent to join together metal powder build material with binding agent disposed thereon and 2) evaporates a solvent of the binding agent.

Abstract: Described herein are methods and systems for printing a three-dimensional object. In an example, a method for printing a three-dimensional object can comprise: (i) a metallic build material being applied; (ii) a binder fluid being applied on at least a portion of the metallic build material; (iii) the selectively applied binder fluid can be flash fused to bind the metallic build material and the selectively applied binder fluid by application of an energy flux having an energy density of from about 0.5 J/cm2 to about 20 J/cm2 for less than about 1 second. In the example, (i), (ii), and (iii) can be repeated at least one time to form the three-dimensional object. The binder fluid can comprise a liquid vehicle and polymer particles dispersed in the liquid vehicle
