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.
