1. A container comprising:
a chamber for storing build material for a three-dimensional printing system;
an opening co-axial with a longitudinal axis of the chamber for coupling to the three-dimensional printing system; and
a material-conveying member mounted within the chamber and arranged within the opening to guide build material between the chamber and the three-dimensional printing system during rotation, wherein the material-conveying member is a screw; and
a connecting member between the material-conveying member and the opening to prevent relative motion between the material conveying member and the opening;
wherein the container is configured such that rotation of the chamber in a first direction about the longitudinal axis of the chamber conveys build material in the chamber to the three-dimensional printing system and rotation of the chamber in a second direction about the longitudinal axis conveys the build material away from the three-dimensional printing system, and
wherein the container is configured such that, on rotation of the chamber:
the material-conveying member is rotated in a same direction as the chamber; and
there is no relative motion between the material-conveying member and the opening.
