Abstract: 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.

Abstract: Examples of an inlet to enable a forced air flow to enter a build material container in a 3D additive manufacturing system are described. In one case, the inlet has a structure having an inner face and an outer face forming at least one aperture through the structure through which forced air flows in use. The inlet has a longitudinal axis and the inner face and outer face are non-aligned along at least one axis which passes through each of inner face and the outer face and is substantially parallel to the longitudinal axis.

Abstract: A 3D printing build material container outlet structure is described. The outlet structure comprises a valve element having an open configuration to enable a tube, when inserted in the outlet structure, to aspirate build material from the container; and a closed configuration to inhibit build material from exiting the container. The valve element changes from the closed configuration to the open configuration by at least one of: the tube being inserted in the outlet structure; and a vacuum force being applied to the outlet structure when the tube has been inserted in the outlet structure.

Abstract: An additive-manufacturing build-material container (201) comprises a reservoir to hold build material, an outlet opening in a top portion of the reservoir, an outlet tube structure including a longitudinal collection unit to collect build material from the bottom and guide the build material to the outlet opening at the top, upon application of a suction force at the other end thereof, and to guide the collected build material to the outlet opening at the top; and a vent opening in a top portion of the reservoir to admit gas from outside the reservoir into the reservoir to follow a gas flow path through the vent opening, through the reservoir and into said one end of the longitudinal collection tube; wherein on said gas flow path there is at least one turbulent-gas-flow-generation feature (237) to generate turbulent gas flow in a region that is within the reservoir and outside the longitudinal collection tube.

Abstract: 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.
