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: The invention refers to a method of generating a ceiling gas stream (44) in the course of the generative manufacturing of a three-dimensional object (2) in a process chamber (3) by a layer-by-layer application and selective solidification of a building material (13) within a build area (10) arranged in the process chamber. In the course of this, the process chamber has a chamber wall (4) having a process chamber ceiling (4a) lying above the build area (10). According to the invention, at least temporarily before and/or during and/or after the manufacturing of the object (2), a ceiling gas stream (44) of a process gas is passed through the process chamber (3) which is streaming from the process chamber ceiling (4a) towards the build area (10) in a controlled manner. In the course of this, the ceiling gas stream (44) is supplied to the process chamber (3) through multiple ceiling inlets (45, 53) formed in the process chamber ceiling (4a) which are distributed over a region of the process chamber ceiling (4a) and which are designed and/or arranged and/or controlled such that the ceiling gas stream (44) is directed substantially perpendicularly to the build area (10) downwards onto the build area as it exits the ceiling inlets (45, 53).

Abstract: A method for gas atomization of a titanium alloy, nickel alloy, or other alumina (Al2O3)-forming alloy wherein the atomized particles are exposed as they solidify and cool in a very short time to multiple gaseous reactive agents for the in-situ formation of a passivation reaction film on the atomized particles wherein the reaction film retains a precursor halogen alloying element that is subsequently introduced into a microstructure formed by subsequent thermally processing of the atomized particles to improve oxidation resistance.

Abstract: Catalyst extraction from polycrystalline diamond table may be achieved by treating with a halogen (in the gas phase or dissolved in a nonpolar organic solvent) to convert the catalyzing material to a salt. Then, polar organic solvents may optionally be used to leach the salt from the polycrystalline diamond table. The polycrystalline diamond (with the salt of the catalyzing material present or at least partially leached therefrom) may be brazed to a hard composite substrate to produce a cutter suitable for use in a matrix drill bit.

Abstract: A method of deoxygenating metal can include forming a mixture of: a metal having oxygen dissolved therein in a solid solution, at least one of metallic magnesium and magnesium hydride, and a magnesium-containing salt. The mixture can be heated at a deoxygenation temperature for a period of time under a hydrogen-containing atmosphere to form a deoxygenated metal. The deoxygenated metal can then be cooled. The deoxygenated metal can optionally be subjected to leaching to remove by-products, followed by washing and drying to produce a final deoxygenated metal.
