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: 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: Apparatus and methods for making metal-connected particle articles. A metal containing fluid is selectively applied to a layer of particles. The metal in the fluid is used to form metal connections between particles. The metal connections are formed at temperatures below the sintering temperature of the particles in the layer of particles.
