摘要： A build material container outlet structure, and a build material nozzle structure is described. The build material container outlet structure comprises a connector to releasably connect to a nozzle structure of an external aspiration system. The outlet structure comprises an aspiration channel to aspire build material from a build material container to the nozzle structure of the external aspiration system. The outlet structure comprises a protrusion protruding from an inner wall of the aspiration channel, to extend into an end portion of a tube of the nozzle structure that is inserted into the aspiration channel and retain a valve element of the nozzle structure in an open configuration.

摘要： In an example, a data unit includes a data unit mounting having a circuitry region, a registration portion, and a retaining feature. Circuitry comprising a data source to provide at least one additive manufacturing parameter is arranged on the circuitry region of the mounting. The data unit mounting is to be removably mounted on a receiving portion of an additive manufacturing build material component, such that the registration portion is to be received in a corresponding guide portion of the receiving portion of the additive manufacturing build material component, and the retaining feature is prevent removal of the data unit from the receiving portion unless deformed. Deformation of the retaining feature to effect removal of the data unit from the receiving portion may be a permanent deformation.

摘要： An additive-manufacturing build-material container comprises a reservoir to hold build material, a build-material outlet structure to allow build material to exit the reservoir through an outlet opening in a top portion of the reservoir, a longitudinal collection unit (313a) to collect build material from the bottom and guide the build material to the outlet opening at the top, and bottom-venting structure to admit vent gas into a bottom portion of the reservoir. The bottom-venting structure may include a vent tube to admit venting gas into the bottom portion of the reservoir. A concentric collection tube structure may be employed including the longitudinal collection tube nested within a vent tube (333A, 354A). The concentric collection tube structure may be mounted along the central axis of the reservoir.

摘要： A 3D printing cleaning module comprises an extraction gate at a lateral wall of a housing; and a platform within the housing to support a build bed including 3D printed parts and un-solidified build material. The platform is tilted or tiltable with respect to a horizontal plane towards the extraction gate to enable 3D printed parts on the platform to be removable through the extraction gate. The module comprises a cleaning engine to remove at least part of the un-solidified build material from the housing, a vibrating mechanism to vibrate the platform; and a controller. The controller is to control the cleaning engine to execute a cleaning operation by removing un-solidified build material from the housing, to cause the part ejection gate to open upon completion of the cleaning operation, and to cause the vibrating mechanism to vibrate the platform when the part extraction gate is in the open position.

摘要： An example of an apparatus to transfer additive manufacturing build material from a container is disclosed. The example disclosed herein comprises a holding structure and a conduit. The holding structure comprises a fixation element to physically attach the holding structure to one or multiple sides of the container. The conduit may be couplable to a vacuum system through a vacuum open end to extract the build material. The holding structure receives and positions the conduit substantially vertically such that a build material extraction open end of the conduit is positioned towards the base of the container. The vacuum open end and the build material extraction open end are opposite open ends from the conduit.

摘要： A cooling unit can be coupled to a build unit of a 3D printing system. The cooling unit comprises a cooling unit opening which is arranged to face a build unit opening when the cooling unit is coupled to the build unit to enable transfer of content from the build unit to the cooling unit. The cooling unit further comprises a self-locking latch mechanism to couple the cooling unit to the build unit such that the cooling unit opening faces the build unit opening.
