Abstract: Examples of a gas inlet structure (1130) and a deformable structure (1120) to store build material (1126) are described. The gas inlet structure may be coupled to the deformable structure. The deformable structure may also have an outlet (1121) that is connectable to an element (1122) of an aspiration system of a three-dimensional printing system, to allow build material to be supplied from the deformable structure on application of a vacuum by the aspiration system. While the vacuum is applied to the outlet, a valve of the gas inlet structure may be selectively actuated to allow gas flow into the deformable structure.

Abstract: Examples of the present disclosure relate to a build material container for a three-dimensional printing system. The container has an external casing with an upper surface, a lower compartment to receive a build material reservoir, at least one load-bearing element, and an upper compartment below the upper surface. The upper compartment and the lower compartment are separated by a lower surface. The at least one load-bearing element is arranged below the lower surface. The upper compartment has stiffening members arranged to distribute load received from the upper surface to the at least one load-bearing element.

Abstract: Examples of the present disclosure relate to a build material container for a three-dimensional printing system. The container has an external casing and a plurality of reservoirs within the external casing. Each reservoir has an outlet to supply build material stored within the reservoir.

Abstract: Certain examples of a build material container for a three-dimensional printing system is described. The build material container has an external casing and an internal compartment within the external casing. The internal compartment may have a reservoir to store build material, where the reservoir has a channel structure, and a surround that encloses the reservoir. A partition is provided within which the channel structure is mounted, the partition forming an upper surface of the internal compartment and being independent from the external casing and the surround. The partition restricts access to the internal compartment and collects build material during use of the channel structure.
