Abstract: In an example of a method for three-dimensional (3D) printing, build material layers are patterned to form an intermediate structure. During patterning, a binding agent is selectively applied to define a patterned intermediate part. Also during patterning, i) the binding agent and a separate agent including a gas precursor are, or ii) a combined agent including a binder and the gas precursor is, selectively applied to define a build material support structure adjacent to at least a portion of the patterned intermediate part. The intermediate structure is heated to a temperature that activates the gas precursor to create gas pockets in the build material support structure.

Abstract: A first camera and a second camera oriented at different angles and spaced a separation distance to determine surface height measurements. The cameras are focused at a lens focal length to a surface area to record a captured image pair of x-y pixels having common features of the surface area. Correlation of the captured image pair is performed to measure a set of disparity distances between the common features in the captured image pair using a fiducial to assist. The set of disparity distances is converted to a set of z-height measurements with a resolution incorporating the separation distance, the lens focal length, the set of disparity distances, and a calibration error factor.

Abstract: In a three-dimensional printing method example, a liquid functional agent is selectively applied. The liquid functional agent includes an alloying agent. A metallic build material is applied. The liquid functional agent is selectively applied before the metallic build material, after the metallic build material, or both before and after the metallic build material. The liquid functional agent patterns the metallic build material to form a composite layer. At least some of the metallic build material is exposed to energy to melt the at least some of the metallic build material to form a layer. Upon contact or after energy exposure, the alloying agent and the build material alter a composition of the composite layer.

Abstract: In an example of a method for three-dimensional printing, a first amount of a binding agent is selectively applied, based on a 3D object model, to individual build material layers of a particulate build material including metal particles to forming an intermediate structure. The binding agent and/or a void-formation agent is selectively applied, based on the 3D object model, to at least one interior layer of the individual build material layers so that a total amount of the binding agent, the void-formation agent, or both the binding agent and the void-formation agent in the at least one of the individual build material layers is greater than the first amount. This patterns an area that is to contain voids. The intermediate structure is heated to form a 3D structure including a void-containing breakable connection.

Abstract: An example of a method for making a build material composition for three-dimensional (3D) printing includes freezing a dispersion of flow additive nanoparticles in a liquid to form a frozen liquid containing the flow additive nanoparticles. The frozen liquid containing the flow additive nanoparticles is lyophilized to form flow additive agglomerates having a porous, fractal structure. The flow additive agglomerates are mixed with a host metal. The flow additive nanoparticles have an average flow additive particle size ranging from about 1 to about 3 orders of magnitude smaller than an average host metal particle size of the host metal.

Abstract: In a three-dimensional printing method example, a liquid functional agent is selectively applied. The liquid functional agent includes i) an energy source material or ii) an energy sink material. A metallic or ceramic build material is applied. The liquid functional agent is selectively applied any of before the metallic or ceramic build material, after the metallic or ceramic build material, or both before and after the metallic or ceramic build material. The liquid functional agent patterns the metallic or ceramic build material to form a composite layer. At least some of the metallic or ceramic build material is exposed to energy. A reaction involving i) the energy source material or ii) the energy sink material is initiated to alter a thermal condition of the composite layer.

Abstract: An electronic device includes a housing enclosure, which at least sealingly contains an electronic component, a barrier, a pump, and a coolant. The electronic component is located on a substrate, while the barrier defines a circulation loop in which the coolant is exposed to the electronic component. The pump is positioned within the circulation loop to cause flow of the coolant through the circulation loop along one side of the at least one barrier in one direction and along an opposite side of the at least one barrier in an opposite direction.

Abstract: An example of a composition includes a host metal present in an amount ranging from about 95.00 weight percent to about 99.99 weight percent, based on a total weight of the composition. A flow additive is also present in an amount ranging from about 0.01 weight percent to about 5.00 weight percent, based on the total weight of the composition. The flow additive consists of an organic material that is pyrolyzable at a pyrolysis temperature that is less than a sintering temperature of the host metal. The composition is spreadable, having a Hausner Ratio less than 1.25.
