Abstract: According to an example, a three-dimensional (3D) printed object may include a body formed of an electrically non-conductive material. In addition, an electrically conductive channel, a sensing device, and a signal emitter may be embedded within the body. The sensing device may be in electrical communication with the electrically conductive channel such that the sensing device is affected by a disruption in a current applied through the electrically conductive channel. In addition, the signal emitter may emit a wireless signal in response to the sensing device being affected by a disruption in the applied current.

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: A device comprising a material distributor and a fluid dispenser. The material distributor to distribute a build material, layer-by-layer, to form a 3D object. A fluid dispenser to selectively dispense in at least some of the respective layers a first fluid agent and a second fluid agent. The first fluid agent, comprising a first color, is to be dispensed at first selectable voxel locations to affect a first material property of a first portion of the 3D object. The second fluid agent, comprising a second color, is to be dispensed at second selectable voxel locations to at least partially disguise the first color of the first portion of the 3D object.
