A method is provided for printing a three-dimensional object. The method comprises, depositing a layer of metal powder onto a powder bed of a three-dimensional printer. A liquid is heated to generate a vapor. The liquid is removed from the vapor to dry the vapor by heating the vapor above a condensation temperature of the liquid. The dry vapor is deposited onto the powder bed of the three-dimensional printer.

Disclosed is a manufacturing device for the additive manufacturing of a three-dimensional object, wherein the object is manufactured by applying a building material layer by layer and selective solidification of the building material, at points in each layer which are assigned in this layer to the cross-section of the object. The points are scanned with at least one exposure area. The movable gas outlet is assigned during operation to a reference process point and/or a target flow supply zone of the movable gas outlet assigned to the reference process point for the flow supply with the process gas and/or the target ventilation zone of the movable gas outlet.

The invention relates to a process and a system for 3-dimentional (3D) fabrication of sub-micron structures and is established by local electrochemical deposition methods.

A method of manufacturing a sized powder metal component having improved fatigue strength. The method includes the sequential steps of solutionizing a sintered powder metal component and quenching the sintered powder metal component, sizing the sintered powder metal component to form a sized powder metal component, re-solutionizing the sized powder metal component, and ageing the sized powder metal component. The sized powder metal component made by this method, in which the component is re-solutionized between sizing before ageing, can exhibit exceptional improvements in fatigue strength compared to components prepared similarly but that are not re-solutionized.
