Abstract: A 3D printer is disclosed herein. The 3D printer comprises a build material distributor to generate layers of a build material in a spreading direction along a spreading axis; a resonator mounted on the build material distributor to vibrate the build material distributor along the spreading axis at a frequency; and a controller. The controller is to control the resonator to vibrate the build material distributor at the frequency while controlling the build material distributor to spread a volume of build material over a platform to generate a layer of build material.

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 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 a metal containing compound that is reducible to an elemental metal in a reducing environment at a reducing temperature less than or equal to a sintering temperature of the host metal. The elemental metal is capable of being incorporated into a bulk metal phase of the host metal in a final metal object. The composition is spreadable, having a Hausner Ratio less than 1.25.

Abstract: In a three-dimensional printing method example, an epoxy mold compound build material is applied. A fusing agent is selectively applied on at least a portion of the epoxy mold compound build material. The epoxy mold compound build material is exposed to energy, thereby fusing the portion of the epoxy mold compound build material in contact with the fusing agent to form a layer.

Abstract: A metallic build material granule includes a plurality of primary metal particles and a temporary binder agglomerating the plurality of primary metal particles together. The primary metal particles have a primary metal particle size ranging from about the 1 μm to about 20 μm. The primary metal particles are non-shape memory metal particles, and the metallic build material granule excludes shape memory metal particles.

Abstract: A multi-fluid kit for three-dimensional printing can include a wetting agent and a binding agent. The wetting agent can include from 0 wt % to about 49.8 wt % water, from about 0.5 wt % to about 30 wt % film-forming organic solvent that can have a boiling point from greater than about 100° C. to about 350° C., and from about 30 wt % to about 99.5 wt % amphiphilic solvent that can have a boiling point from about 45° C. to less than about 100° C. The amphiphilic solvent can be water-miscible and can be present in the wetting agent at a greater concentration than the water and at a greater concentration than the film-forming solvent. The binding agent can include from about 2 wt % to about 30 wt % of a polymer binder dispersed in an aqueous liquid vehicle.

Abstract: In a three-dimensional (3D) printing method example, a metallic build material is applied. A binder fluid is selectively applied on at least a portion of the metallic build material. The binder fluid includes a liquid vehicle and polymer particles dispersed in the liquid vehicle. The application of the metallic build material and the selective application of the binder fluid are repeated to create a patterned green part. The patterned green part is heated to at about a melting point of the polymer particles to activate the binder fluid and create a cured green part. The cured green part is heated to a thermal decomposition temperature of the polymer particles to create an at least substantially polymer-free gray part. The at least substantially polymer-free gray part is heated to a sintering temperature to form a metallic part.
