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 one example in accordance with the present disclosure, an additive manufacturing system is described. The additive manufacturing system includes a build material distributor to deposit layers of powdered build material onto a bed to form a three-dimensional (3D) printed object. The additive manufacturing system also includes a controller to interrupt printing of the 3D printed object and to resume printing of the 3D printed object. The additive manufacturing system also includes a heat source to, during an interruption in printing, maintain a temperature of a top surface of the powdered build material between a solidification temperature and a melting temperature for the build material.

Abstract: In a three-dimensional printing method example, a metallic build material is applied. A positive masking agent is selectively applied on at least a portion of the metallic build material. The positive masking agent includes a radiation absorption amplifier that is compatible with the metallic build material. The metallic build material is exposed to radiation from a spatially broad, high energy light source to melt the portion of the metallic build material in contact with the positive masking agent to form a layer. The radiation absorption amplifier i) has an absorbance for the radiation that is higher than an absorbance for the radiation of the metallic build material, or ii) modifies a surface topography of the at least the portion of the metallic build material to reduce specular reflection of the radiation off of the at least the portion of the metallic build material, or both i) and ii).

Abstract: Apparatus and methods for making metal-connected particle articles. A metal containing fluid is selectively applied to a layer of particles. The metal in the fluid is used to form metal connections between particles. The metal connections are formed at temperatures below the sintering temperature of the particles in the layer of particles.

Abstract: In an example method for forming three-dimensional (3D) printed electronic parts, a build material is applied. An electronic agent is selectively applied in a plurality of passes on a portion of the build material. A fusing agent is also selectively applied on the portion of the build material. The build material is exposed to radiation in a plurality of heating events. During at least one of the plurality of heating events, the portion of the build material in contact with the fusing agent fuses to form a region of a layer. The region of the layer exhibits an electronic property. An order of the plurality of passes, the selective application of the fusing agent, and the plurality of heating events is controlled to control a mechanical property of the layer and the electronic property of the region.

Abstract: A three-dimensional (3D) printing method includes applying a build material composition having a polymer particle and a radiation absorbing additive mixed with the polymer particle, the radiation absorbing additive being selected from the group consisting of inorganic near-infrared absorbers, organic near-infrared absorbers, and combinations thereof. The build material composition is preheated to a temperature below the melting temperature of the polymer particle by exposing the build material composition to radiation, the radiation absorbing additive increasing radiation absorption and accelerating the pre-heating of the build material composition. A fusing agent is selectively applied on at least a portion of the build material composition. The method further includes exposing the build material composition to radiation, whereby at least the polymer particle in the at least the portion of the build material composition in contact with the fusing agent at least partially fuses.
