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.
