Abstract: Described herein are methods and systems for printing a three-dimensional object. In an example, a method for printing a three-dimensional object can comprise: (i) a metallic build material being applied; (ii) a binder fluid being applied on at least a portion of the metallic build material; (iii) the selectively applied binder fluid can be flash fused to bind the metallic build material and the selectively applied binder fluid by application of an energy flux having an energy density of from about 0.5 J/cm2 to about 20 J/cm2 for less than about 1 second. In the example, (i), (ii), and (iii) can be repeated at least one time to form the three-dimensional object. The binder fluid can comprise a liquid vehicle and polymer particles dispersed in the liquid vehicle

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: The present disclosure is drawn to a material set including a powder bed material and a binder fluid. The powder bed material can be from 80 wt % to 100 wt % metal particles having a metal core and a thin metal layer on the core, and the metal particles having a D50 particle size distribution value ranging from 4 μm to 150 μm and the thin metal layer having an average thickness from 20 nm to 2 μm. The binder fluid can adhere a first portion of the powder bed material relative to a second portion of the powder bed material not in contact with the binder fluid.

Abstract: In one example, an apparatus for generating a three-dimensional object includes an energy source to apply energy to a layer of build material to cause a first portion of the layer to coalesce and solidify, an agent distributor to selectively deliver a cooling agent onto a second portion of the layer, and a controller to control the energy source to apply energy to the layer to cause the first portion to coalesce and solidify in a first pattern and to control the agent distributor to selectively deliver the cooling agent onto the second portion of the layer in a second pattern independent of the first pattern.

Abstract: In one example, a lighting device for an additive manufacturing machine includes first light sources each to emit monochromatic light within a first band of wavelengths that includes a peak light absorption of a liquid coalescing agent and second light sources each to emit monochromatic light within a second band of wavelengths different from the first band of wavelengths. Each of the first light sources or each of multiple groups of the first light sources is individually addressable to emit monochromatic light independent of any other of the first light sources or of any other group of the first light sources and each of the second light sources or each of multiple groups of the second light sources is individually addressable to emit monochromatic light independent of any other of the second light sources or of any other group of the second light sources.

Abstract: An example method for additive manufacturing of metals includes spreading a build material including a metal in a sequence of layers. Each layer has a respective thickness, a respective sequence position, and a respective exposed surface to receive radiated energy from a flood energy source prior to spreading of a subsequent layer. A energy function is determined based on the metal, the thickness, and the sequence position of an exposed layer. The energy function defines the radiated energy and includes an intensity profile and a fluence sufficient to cause a consolidating transformation of the build material in the exposed layer. The exposed surface of the exposed layer is exposed to the radiated energy from the flood energy source, causing the consolidating transformation of the build material in the exposed layer.
