摘要： Methods for manufacturing a beryllium-based article object comprising beryllium by depositing layers of beryllium. An element is added to the beryllium that dissolved to form a secondary phase to limit columnar grain. Grain refinement allows the beryllium article to have beneficial properties in terms of strength and durability.

摘要： Described herein are methods and systems for printing a three-dimensional object. In an example, a method for printing a three-dimensional object can comprise: (i) a metallic build material being applied; (ii) a binder fluid being applied on at least a portion of the metallic build material; (iii) the selectively applied binder fluid can be flash fused to bind the metallic build material and the selectively applied binder fluid by application of an energy flux having an energy density of from about 0.5 J/cm2 to about 20 J/cm2 for less than about 1 second. In the example, (i), (ii), and (iii) can be repeated at least one time to form the three-dimensional object. The binder fluid can comprise a liquid vehicle and polymer particles dispersed in the liquid vehicle.

摘要： A three-dimensional PBF-AM apparatus includes a stage on which a powder material is spread, and a tubular build box disposed in a state of surrounding the stage. The build box includes a side wall portion having a first tubular member surrounding the stage and a second tubular member surrounding the stage with the first tubular member interposed therebetween and forming a space with the first tubular member, and moreover, a vacuum heat insulating layer can be formed inside the side wall portion by vacuuming the space.

摘要： A method, product, apparatus, and article of manufacture for the application of the Composite Based Additive Manufacturing (CBAM) method to produce objects in metal, and in metal fiber hybrids or composites. The approach has many advantages, including the ability to produce more complex geometries than conventional methods such as milling and casting, improved material properties, higher production rates and the elimination of complex fixturing, complex tool paths and tool changes and, for casting, the need for patterns and tools. The approach works by slicing a 3D model, selectively printing a fluid onto a sheet of substrate material for each layer based on the model, flooding onto the substrate a powdered metal to which the fluid adheres in printed areas, clamping and aligning a stack of coated sheets, heating the stacked sheets to melt the powdered metal and fuse the layers of substrate, and removing excess powder and unfused substrate.

摘要： A particulate for an additive manufacturing technique includes metallic particulate bodies with exterior surfaces bearing a polymeric coating. The polymeric coating is conformally disposed over the exterior surface that prevents the underlying metallic body from oxidation upon exposure to the ambient environment by isolating the metallic particulate bodies from the ambient environment. Feedstock materials for additive manufacturing techniques, and methods of making such feedstock, are also disclosed.
