Abstract: A build material management system for a 3D printing system is described in which one or more input ports of a housing of the build material management system is to connect to one or more respective transportable containers. The transportable containers contain a volume of build material comprising 3D printed parts and a portion of non-fused build material. A pump also comprised within the housing is operable to provide a pressure differential across a conduit network of the build material management system. The pump is connected to the input port(s) by the conduit network. An air-flow caused through at least one of the one or more input ports is controlled by processing circuitry also comprised within the housing. The air-flow causes cooling within the respective transportable container. In one alternative, the housing comprises at least two input ports. In all other alternatives, a filling port for filling the or a further transportable container with at least a portion of fresh build material for use in a subsequent 3D printing operation is not comprised within the housing.

Abstract: In some examples, a media stacker includes a drawer defining a chamber, and a plurality of moving elements to engage media sheets of different sizes as the media sheets are output from a system. The plurality of moving elements are to slide the media sheets to a target position in the drawer, and the plurality of moving elements are to disengage from the media sheets once the media sheets have reached the target position. A plurality of retaining elements are to engage the media sheets of the different sizes as the media sheets slide into the drawer.

Abstract: A method of three-dimensional (3D) printing is provided. Print data is received, which defines patterns of at least one agent to be applied to a layer of build material. These patterns are at least partially based on a 3D model of at least one object to be generated. The print data print data is processed to determine regions which are distant from said patterns. The print data is modified to add a further pattern of a detailing agent to be selectively applied to the layer of build material to generate fracture regions in a processed volume of build material.

Abstract: There are disclosed methods and apparatuses for 3D printing post-processing. The methods and apparatuses provide a container for an additive manufacturing system, the container for receiving a build volume of fused and unfused build material. The container comprises a connector for connecting the container to a pressure source, and at least one air hole to allow passage of air into or out of the container. When the connector is connected to the pressure source, air flows through the container between the connector and the at least one air hole so as to remove unfused build material from the container and to help cool the volume of build material.
