    Abstract: In an example, a method includes operating, by a processor, on object model data and operating, on a processor, on pattern data. The object model data describes at least part of an object to be generated in additive manufacturing and the pattern data describes an object pattern intended to be formed on at least a portion of the part of the object to be generated in additive manufacturing. The method includes determining, by a processor, control data to control a print agent applicator to apply a pattern of fusing agent onto a part of a layer of build material. The pattern of fusing agent comprises a fusing agent area and a gap area that lacks fusing agent. The gap area corresponds to the object pattern such that no fusing agent is applied to a part of the layer of build material that corresponds to the object pattern.

    Abstract: Examples of methods are described. In some examples, a method may include printing a first solid material phase region. In some examples, the method may include printing a second solid material phase region distanced from the first solid material phase region. In some examples, the method may include printing a plurality of distanced beams, each having a thickness that is not more than one millimeter, to form a weak material phase region between the first solid material phase region and the second solid material phase region. In some examples, the weak material phase region has a volumetric density less than one.

    Abstract: A device includes a material dispenser and a fluid dispenser. The material dispenser is to dispense a build material layer-by-layer, to at least partially additively form a first 3D object. The fluid dispenser is to dispense at least one fluid agent at selectable exterior voxel locations of the respective layers to at least partially define an external surface of the first 3D object as a first color to represent a first non-color material property of at least a first portion of the first 3D object. The selection of the first color is independent of characteristics of the first non-color material property.

    Abstract: An example system includes a plurality of energy emitters to deliver energy to a material bed to fuse build material at a plurality of locations receiving the energy. The system also includes a controller to a controller to determine an amount of energy to deliver to each location to achieve a fusing condition based on data indicating the plurality of locations to be fused and based on predicted thermal transfer between the plurality of locations receiving the energy. The controller also is to cause the plurality of energy emitters to deliver the determined amount of energy to each location of the material bed.

    Abstract: Some examples include an additive manufacturing system including a processor and a memory to store instructions to cause the processor to ate print data related to a three-dimensional build object. The generated print data comprises defined print data to print a first part and a second part of the object. The defined print data is to orient and position each of the first part and the second part of the object within a build area, the first part including a first mating section, the second part including a second mating section, the first and second mating sections shaped and sized to be matingly coupled to form the build object, to adjacently align the first and second mating sections within the build area, and to separate the aligned first and second mating sections with a gap defined between the first and second parts along the aligned first and second mating sections.
