Abstract: In an example of a 3D printing method, build material particles are applied to form a layer. Each build material particle includes a metal core and a metal oxide outer shell. The layer is patterned by selectively applying a reactive chemical on at least a portion of the layer to initiate a redox reaction with the metal oxide outer shells of the build material particles in contact with the reactive chemical, which reduces the metal oxide outer shells of the build material particles in contact with the reactive chemical and exposes the metal cores of the build material particles in contact with the reactive chemical. The patterned layer is exposed to rapid thermal processing to sinter the exposed metal cores to form a part layer. Any intact build material particles remain unsintered.

Abstract: Methods of generating a three-dimensional object with an additive manufacturing system are described. The method includes depositing a build material within a working area, thereby providing a build material layer, selectively depositing a fusing agent onto a portion of the build material layer, applying energy from a bulk-fusion energy source to the working area, thereby fusing at least a portion of the build material where the fusing agent is deposited, and applying energy from a focused energy source to one or more localized areas of the working area.

Abstract: A spherical identifier may, in an example, include a sphere including a plurality of shells forming the sphere, a radially-defined code being discernable using the arrangement of the plurality of shells. A three-dimensional object identifier may, in an example, include a number of spheres manufactured into the body of the three-dimensional object wherein each of the spheres comprise a plurality of shells; the shells constituting a radially definable code.

Abstract: In some examples, a data representation is received that includes voxels relating to a volumetric property and a functional property of portions of a three-dimensional (3D) object to be formed by a 3D printing system, and trajectory voxels containing information to guide operation of a machine that manipulates portions of the 3D object during 3D printing. Information of the voxels relating to the volumetric property and the functional property and the information of the trajectory voxels are combined to produce instructions that control the 3D printing system to build the 3D object.

Abstract: According to an example, an apparatus may include a printhead to deliver a printing liquid from firing chambers through a plurality of bores arranged along a surface of the printhead. The apparatus may also include a cleaning system to apply a pressurized cleaning fluid onto the surface of the printhead while preventing application of the pressurized cleaning fluid into the firing chambers through the plurality of bores.
