Abstract: In an example of a method for making polymer-encapsulated metallic ink pigment particles, a layer of a transparent resin dispersion is disposed on a flexible substrate. The resin dispersion layer is substantially dried, and a base resin layer is formed. A slurry is disposed onto the base resin layer. The slurry includes metallic pigment particles and polymer particles dispersed in a non-aqueous carrier. The slurry is dried to form a metallic pigment-polymer sheet. Another layer of the transparent resin dispersion is disposed on the metallic pigment-polymer sheet and is dried. A coating resin layer is formed. The metallic pigment-polymer sheet and the base and coating transparent resin layers form a tri-layer film having the metallic pigment particles encapsulated between the base and coating transparent resin layers.

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.

Abstract: In an example 3D printing method, an electrical conductivity value for a resistor is identified. Based upon the identified electrical conductivity value, a predetermined amount of a conductive agent is selectively applied to at least a portion of a build material layer in order to introduce a predetermined volume percentage of a conductive material to the resistor. Based upon the identified electrical conductivity value and the predetermined volume percent of the conductive material, a predetermined amount of a resistive agent is selectively applied to the at least a portion of the build material layer in order to introduce a predetermined volume percentage of a resistive material to the resistor. The build material layer is exposed to electromagnetic radiation, whereby the at least the portion coalesces to form a layer of the resistor.

Abstract: Apparatus to produce a three-dimensional object and methods of producing a three-dimensional object are described. In some examples, a first fluid comprising a colorant and a second fluid comprising an absorber to absorb electromagnetic radiation are applied on a layer of particulate material. Application of the second fluid to the layer of particulate material is in dependence on an ability of the first fluid to absorb the electromagnetic radiation.

Abstract: According to an example, a three-dimensional (3D) printer may include a delivery device to deposit a light absorbing agent onto selected areas of a layer of build material particles, in which the light absorbing agent absorbs light having wavelengths that are around the ultraviolet wavelength range. The 3D printer may also include a light source to apply light onto the selectively deposited light absorbing agent and the layer of the build material particles, in which the light absorbing agent absorbs light around the ultraviolet wavelength range from the applied light and becomes heated to a temperature that causes the build material particles upon which the light absorbing agent has been deposited to melt and to fuse together following cessation of the application of the light.
