Abstract: In an example, a method includes forming a layer of build material, processing a first portion of the build material by distributing a print agent using a first distribution pattern, the first distribution pattern having a first print agent dispersion characteristic and processing a second portion of the build material by distributing a print agent using a second distribution pattern, the second distribution pattern having a second print agent dispersion characteristic. The method may further include heating the build material by exposing the layer of build material to radiation so as to cause fusing of the first and second portion.

Abstract: In an example, a method includes providing a build material. Print agent comprising colorant may be applied to a first portion of the build material to be fused in additive manufacturing, wherein the print agent is applied according to a target color for the first portion. A combination of a fusion inhibiting agent and colorant may be applied to a second portion of the build material, wherein the print agent is applied according to the target color of the first portion and the second portion is adjacent to the first portion. The method may further include heating the build material by exposing the build material to radiation so as to cause fusing of the first portion.

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: In an example, a virtual build volume comprising a representation of at least a part of an object to be generated in additive manufacturing is segmented into a plurality of nested segments comprising a core segment, an inner peripheral segment and an outer peripheral segment. Additive manufacturing control instructions may be generated for the nested segments. The control instructions for the core segment may provide a first region of the object corresponding to the core segment and having a first color. The control instructions for the outer peripheral segment may provide a second color for a second region of the object corresponding to the outer peripheral segment. The control instructions for the inner peripheral segment may provide a third color for a third region of the object corresponding to the inner peripheral segment, wherein a color of the third region is determined so as to at least partially visually mask the first region.

Abstract: In an example, a method includes determining an additive manufacturing process instruction, the additive manufacturing process instruction comprising an instruction specifying a coverage of a set of print agents comprising a fusing agent and a colorant to be applied to build material. A color and a behavioural property of carrying out an additive manufacturing process according to the additive manufacturing process instruction may be determined and, in response to a determination that the behavioural property meets predetermined parameters, the instruction and the color may be added to a color mapping resource.

Abstract: In an example, a method includes receiving, at a processor, a data model of an object to be generated in additive manufacturing. A virtual build volume comprising a representation of at least a portion of the object may be segmented into a plurality of nested segments comprising a core segment and a peripheral segment. Segmenting the virtual build volume may comprise determining a dimension of the peripheral segment based on at least one of a geometry of the object and an intended object property.

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.

Abstract: In an example, a method includes acquiring data representing an article to be printed. The data may include at least one element set associated with print addressable location(s) and comprising a first and second element. The elements each identify a print material or print material combination and is each associated with a probability that the print material or print material combination identified thereby is to be applied to the associated print addressable location. A halftone matrix may be acquired comprising threshold values of a first and second value range. The threshold values of the first and second value range are distributed according to a first and second distribution pattern respectively. The halftone matrix may be applied to the data to determine print instructions to distribute the print material or print material combination identified by the first and second element according to the first and second distribution patterns respectively.

Abstract: Examples analyze three-dimensional printing specifications associated with a three-dimensional printing device to determine test angles for a test object and test surfaces corresponding to the test angles for the test object. Examples generate the test object for color calibration for the three-dimensional printing device based at least in part on the test angles and test surfaces that are configured with at least one test color.
