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 of a three-dimensional printing method, a polymeric build material is applied. A fusing agent is selectively applied on at least a portion of the polymeric build material. The fusing agent includes cesium tungsten oxide nanoparticles, a zwitterionic stabilizer, and an aqueous vehicle. The polymeric build material is exposed to electromagnetic radiation to fuse the portion of the polymeric build material in contact with the fusing agent to form a layer.

Abstract: An apparatus and method for generating a three-dimensional object. The apparatus includes a build material area, at least one agent distributor with a fluid reservoir to store fluid agent and at least one fluid ejection die to selectively eject fluid agent in the build material area. A cooling system to remove heat from the at least one fluid ejection die has a heat sink. The at least one fluid ejection die is in thermal contact with the heat sink via the fluid agent of the fluid reservoir.

Abstract: In one example, a container includes a rigid hollow core, a bag in the core to hold a printing fluid, and a plug plugging one end of the core. The plug includes a flange covering the edge of the end of the core, a part protruding from the flange into and plugging the end of the core, and a port operatively connected to an outlet from the bag such that printing fluid can flow out of the bag and through the port.

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: 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.
