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: A method for producing a TiAl alloy member includes a molding step (S10) of laminating a solidified body obtained by melting and solidifying or sintering powder of a TiAl alloy by irradiation of the powder with a beam, to mold a laminated body; and a heat treatment step (S12) of heating the laminated body at a setting temperature that is equal to or higher than a temperature at which a phase transformation to an α phase is initiated, to produce a TiAl alloy member. By the method for producing a TiAl alloy member, the TiAl alloy member can be easily molded with a decrease in high temperature properties suppressed.
