Abstract: In an example of a three-dimensional (3D) printing method, a metallic build material is applied. A patterning fluid, including a metal salt, is selectively applied on at least a portion of the metallic build material. Prior to an application of additional build material, the metallic build material is exposed to light irradiation to cause the metal salt to reach a thermal decomposition temperature and thermally decompose to a metal. During the exposing, the metallic build material is maintained below a sintering temperature of the metallic build material.

Abstract: Print glossing is described. Print glossing can be performed on a glossing drum having a location affixed to a circumferential outer surface thereof, where the location transits from a first position in an apparatus having a first temperature range selected to enable reflow of ink applied to a substrate that is placed at the location to a second position in the apparatus having a second temperature range selected for clean release from the location of the ink applied to the substrate.

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 powder bed material can include from 80 wt % to 100 wt % metal particles having a D50 particle size distribution value from 4 μm to 150 μm. From 10 wt % to 100 wt % of the metal particles can be surface-activated metal particles having in intact inner volume and an outer volume with structural defects. The structural defects can exhibit an average surface grain density of 50,000 to 5,000,000 per mm2.

Abstract: A method of three-dimensional printing can include iteratively applying metal particles having a heat fusion temperature as individual build material layers, and based on a 3D object model, iteratively and selectively applying a metallic binding agent onto the individual build material layers so that the individual build material layers are built up and bound together to form a green-body object. The metallic binding agent includes an aqueous liquid vehicle and metal salt or metal oxide nanoparticles that are thermally reducible to a metal or metal alloy at an elevated metal reducing temperature that is lower than the heat fusion temperature. The method also includes iteratively and selectively applying a polymeric binding agent onto the individual build material layers at an interface between the green-body object and a support structure for the green-body object, leaving a residue at the interface.
