    Abstract: In an example implementation, a fluid supply assembly includes a printhead assembly and a carriage comprising a quick-release, hand-operable attachment mechanism to removably attach the printhead assembly to the carriage. A fluid conduit interconnect is rigidly attached to the printhead assembly by a tool-operable fastener. The fluid conduit interconnect is to connect to a fluid conduit to communicate printing fluid from an off-axis printing fluid supply to the printhead assembly.

    Abstract: An example of an apparatus is provided. The apparatus includes a build material transport path to transport a build material with air flow. The apparatus includes a humidifying element to receive the air flow and to add moisture to the air flow. The apparatus includes an inlet to introduce ambient air into the build material transport path to decrease moisture content in the air flow. The apparatus includes a valve to connect the humidifying element and the inlet to the build material transport path. The valve is to adjust an amount of ambient air introduced into the build material transport path. The apparatus includes a sensor to detect the moisture content in the air flow and to generate a signal to indicate the moisture content. The apparatus includes a processor to receive the signal to control the valve to maintain a moisture content in the air flow.

    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. Trie transportable containers contain a volume of build materia! 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 tiuiid material management system. The pump is connected to the input port(s) by t*ie conduit network. An air-flow caused through at least one of the one or more input ports is controlled by processing circuitry a!so comprised within the housing. The air-flow causes cooling within the respective transportable container, !n one alternative, the housing comprises at ieast two input ports. In ai! other alternatives, a filling port for filling the or a further transportable container with at ieast a portion of fresh build materia! for use in a subsequent 3D printing operation is not comprised within the housing.
