    Abstract: A concentrated inkjet ink for packaging includes a liquid composition present in an amount that is less than 60 wt % of the concentrated inkjet ink, and nonvolatile solids present in an amount ranging from about 40 wt % to about 90 wt % of the concentrated inkjet ink. The nonvolatile solids include encapsulated pigment particles having a particle size ranging from about 50 nm to about 500 nm, and a dispersant. The concentrated inkjet ink is dispersible in an ink vehicle to form a print ready inkjet ink.

    Abstract: Methods of forming 3D printed metal objects and compositions for 3D printing are described herein. In an example, a method of forming a 3D printed metal object can comprise: (A): a build material comprising at least one metal being deposited; (B): a fusing agent being selectively jetted on the build material, the fusing agent comprising: (i) at least one hydrated metal salt having a dehydration temperature of from about 100° C. to about 250° C., and (ii) a carrier liquid comprising at least one surfactant and water; (C): the build material and the selectively jetted fusing agent being heated to a temperature of from about 100° C. to about 250° C. to: (a) remove the carrier liquid, (b) dehydrate the hydrated metal salt, and (c) bind the build material and the selectively jetted fusing agent; and (D): (A), (B), and (C) being repeated at least one time to form the 3D printed metal object.

    Abstract: Example described herein include a three-dimensional printer a three-dimensional printing device that includes a fusible material applicator to apply a layer of fusible material, a inhibiting material applicator to apply a patterned layer of inhibiting material to establish exposed regions of the layer of fusible material and blocked regions of the layer of fusible material based on information corresponding to a three-dimensional model, and a photonic energy emitter to apply photonic energy to fuse the exposed regions of the layer of fusible material.

    Abstract: An example of a fusing agent includes a metal bis(dithiolene) complex, a thiol surfactant, a polar aprotic solvent, and a balance of water. In an example of a method of making the fusing agent, the metal bis(dithiolene) complex is exposed to an aqueous solution including a reducing agent and a thiol surfactant to form a reduced metal bis(dithiolene) complex and to dissolve the reduced metal bis(dithiolene) complex in the aqueous solution. The aqueous solution is incorporated into a vehicle including a water soluble organic solvent and an additive selected from the group consisting of an emulsifier, a surface tension reduction agent, a wetting agent, a scale inhibitor, an anti-deceleration agent, a chelating agent, an antimicrobial agent, and a combination thereof. The fusing agent may be utilized in a three-dimensional printing method and/or incorporated into a three-dimensional printing system.
