Abstract: An example of a kit for three-dimensional (3D) printing includes an ultraviolet (UV) light fusing agent and a detailing agent. The UV light fusing agent including an aqueous vehicle and a plasmonic metal nanoparticle that i) provides absorption enhancement at radiation wavelengths ranging from about 340 nm to about 450 nm, and ii) is present in an amount up to 2 wt% based on a total weight of the UV light fusing agent. The detailing agent includes a surfactant, a co-solvent, and water.

Abstract: In one example in accordance with the present disclosure, an additive manufacturing system is described. The additive manufacturing system includes an additive manufacturing device to form a three-dimensional (3D) printed object. The additive manufacturing system also includes a placement device to embed at least a portion of a container structure into the 3D printed object. The container structure expels a payload when a predetermined condition is met. A controller of the additive manufacturing system controls additive manufacturing and placement of the portion of the container structure.

Abstract: In one example in accordance with the present disclosure, a system is described. The system includes a scanner to read three-dimensional (3D) print information from a storage element to be embedded in a 3D printed object. The system also includes a controller. The controller 1) instructs an additive manufacturing device to form the 3D printed object based on the 3D print information stored in the storage element and 2) embeds the storage element into the 3D printed object.

Abstract: In an example, a method includes defining, for an interior portion of an object to be generated in additive manufacturing, an imaging characteristic in a radiation environment. In some examples the method further includes deriving object model data for generating the interior portion of the object by determining an amount of a first contrast agent and an amount of a second contrast agent to deposit such that the object generated according to the object model data comprises the defined imaging characteristic apparent in an image of at least a part of the object comprising the interior portion captured in the radiation environment. The first contrast agent and the second contrast agent may have different imaging characteristics in the radiation environment.

Abstract: In one example in accordance with the present disclosure, an additive manufacturing system is described. The additive manufacturing system includes an additive manufacturing device to form a three-dimensional (3D) printed object. A placement device of the additive manufacturing system is to embed a sensing system into build material used to form the 3D printed object. The sensing system is to measure a manufacturing condition during formation of the 3D printed object. The additive manufacturing system also includes a controller to associate manufacturing condition with the 3D printed object.
