摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： In an example, a method includes receiving object model data describing at least a portion of an object to be generated by additive manufacturing. Object generation instructions for generating the object in its entirety may be derived based on the object model data. Where it is determined that the object model data comprises a data deficiency for deriving the object generation instructions, at least one attribute for the object may be inferred and object generation instructions may be derived based on the object model data and the inferred attribute.
