Abstract: Disclosed herein is a three-dimensional printing method comprising: applying a build material; applying on, at least, a portion of the build material, a low tint fusing agent composition comprising metal oxide nanoparticles dispersed in a liquid vehicle; and exposing the build material to radiations to fuse the portion of the build material in contact with the low tint fusing agent composition in order to form a layer of a 3D object. Also disclosed herein is an article obtained according to the three-dimensional printing method described herein. Such articles comprises a core substrate made of a polymeric build material that has been fused with a core fusing agent composition; a first layer, applied on the surface of the core substrate, comprising a polymeric build material fused with a low tint fusing agent composition including metal oxide nanoparticles dispersed in a liquid vehicle; and a second layer, applied over the surface of the first layer, comprising a polymeric build material fused with a colored ink composition and a core fusing agent or with a low tint fusing agent composition colored ink composition.

Abstract: In an example a method includes identifying, by a processor, in a data model of at least a portion of a three-dimensional object, an object property associated with a location in the three-dimensional object. A data model of a virtual build volume comprising at least a portion of the three-dimensional object may be generated in which an association with an object property is dispersed beyond the location.

Abstract: A control system for a three-dimensional printer includes an energy component interface, an agent depositing component interface, and control logic. The control logic controls the operation of an energy component through the energy component interface and an agent depositing component through the agent depositing component, in forming an output object that is specified in a print job. Additionally, in some examples, the control logic can implement a plurality of modes. Each mode, when selected modulate one or more operational parameters of a least one of the energy component or agent depositing component.
