Abstract: In one example, a liquid-gas separator includes a composite membrane to pass a gas but not a liquid at a first pressure difference across the membrane and to block the gas passing back through the membrane at a second pressure difference smaller than the first pressure difference.

Abstract: According to one aspect, there is provided a method of adding build material to a rotatable 3D printing build material container having an internal build material storage reservoir, the method comprising: providing a supply of build material to an input port of the container; rotating the container about its rotation axis at a first speed sufficient to cause build material within the container to be centrifugally forced against the outside of the internal storage reservoir.

Abstract: Examples of the present disclosure relate to a container. The container has a chamber for storing build material for a three-dimensional printing system. The container comprises an opening coaxial with the chamber for coupling to the three-dimensional printing system. The container is configured such that rotation of the chamber in a first direction conveys build material in the chamber to the three-dimensional printing system and rotation of the chamber in a second direction conveys the build material away from the three-dimensional printing system.
