Abstract: The autogenic canister for metal recycling invention delivers a metal solid from a mixture of metal revert, turnings, chips, sponge, granules, solids, and powders in an automatically generated vacuum sealed canister. The method of delivery involves an indirect extrusion process that incorporates a sealing device around a solid compaction ram. Clean metal particulates are sealed under vacuum within the repeatedly reforming canister. The process avoids common extrusion defects and produces extrusion products using less energy than melting based recycling processes and has fewer processing steps. The invention has environmental and economic advantages over the prior art in solid state recycling of metals.

Abstract: A method for manufacturing a wrought metallic article from metallic-powder compositions comprises steps of (1) compacting the metallic-powder composition to yield a compact, having a surface, a cross-sectional area, and a relative density of less than 100 percent, (2) reducing the cross-sectional area of the compact via an initial forming pass of a rotary incremental forming process so that the compact has a decreased cross-sectional area, and (3) reducing the decreased cross-sectional area of the compact via a subsequent forming pass of the rotary incremental forming process by a greater percentage than that, by which the cross-sectional area of the compact was reduced during the initial forming pass.

Abstract: Aspects of the disclosure are directed to metal-based materials, their manufacture and their use. Certain embodiments involve providing powder in a metal-based foil/shell, and forming a tube from the foil/shell with the powder therein. The tube thus has a metal-based foil shell filled with the powder. Metal wire may be formed by rolling the tube filled with the powder and reducing the diameter of the tube. Certain embodiments are directed to the structure of such a tube prior to wire formation, and other embodiments are directed to the metal wire itself.

Abstract: Disclosed is a conductive ink composition and a manufacturing method thereof. The composition includes about 50 to about 99 wt % copper nanoparticles and about 1 to about 50 wt % tin. Copper nanoparticles are atomized and suspended in a tin bath, wherein the copper nanoparticles are evenly dispersed within the bath through sonification. The composition is cooled, extracted, and formed into a filament for use as a conductive ink. The ink has a resistivity of about 46.2×E−9 Ω*m to about 742.5×E−9 Ω*m. Once in filament form, the tin-copper mix will be viable for material extrusion, thus allowing for a lower cost, electrically conductive traces to be used in additive manufacturing.

Abstract: The invention is a process for manufacturing a nano aluminum/alumina metal matrix composite and composition produced therefrom. The process is characterized by providing an aluminum powder having a natural oxide formation layer and an aluminum oxide content between about 0.1 and about 4.5 wt. % and a specific surface area of from about 0.3 and about 5 m2/g, hot working the aluminum powder, and forming a superfine grained matrix aluminum alloy. Simultaneously there is formed in situ a substantially uniform distribution of nano particles of alumina. The alloy has a substantially linear property/temperature profile, such that physical properties such as strength are substantially maintained even at temperatures of 250° C. and above.

Abstract: A printer fabricates an object from a computerized model using a fused filament fabrication process. The shape of an extrusion nozzle may be varied during extrusion to control, e.g., an amount of build material deposited, a shape of extrudate exiting the nozzle, a feature resolution, and the like.

Abstract: There is disclosed an article which is formed of a solid-phase or liquid-phase sintered product of a metal powder, ceramic powder or glass powder. For manufacturing the article, an extrudable mixture which contains the material powder and a thermoplastic binder is shaped into a continuous filament suitable for use in fused filament 3D printers. The printed object is then invested in plaster or other castable refractory. The invested object is then subjected to heating. The heating process burns off the thermoplastic binder and sinters the powders of metal, glass or ceramic, leaving a pure metal, glass or ceramic object.The extrudable mixture is produced by preparing a material powder, preparing thermoplastic binder, blending the material powder and the thermoplastic binder together. The most preferable extrudable mixture contains 80 to 92% by weight of metal powder, 8 to 20% by weight of thermoplastic binder, and 0.0 to 0.1% unavoidable impurities. The extrudable mixture is then extruded into a continuous filament suitable for use in various 3d printing hardware.
