Abstract: 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.
