  • Patent number: 11173546
    Abstract: 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.

  • Patent number: 10862137
    Abstract: The invention relates to a method for producing a current collector (1) for a fuel cell. The method comprises the following steps: mixing a power-type or granulate-type base material (2) with a binding agent (3) and with fibres (4) in order to generate a material mixture (5), wherein the fibres (4) have a lower melting point and/or a lower chemical resistance than the base material (2); moulding a moulded body (6) from the material mixture (5); debinding the binding agent (3) from the moulded body (6); removing at least one portion of the fibres (4) from the moulded body (6); and sintering the moulded body (6). The invention also relates to a fuel cell having a current collector (1) that is produced by means of a method according to the invention.

  • Patent number: 10793959
    Abstract: A method for making a porous metal article of manufacture is provided. The method includes subjecting a saturated aqueous electrolytic solution wherein silver or copper is a donor in a container with two electrodes, where dendrite crystals of silver or copper or silver or copper nanowires are formed and collected. The collected dendrite crystals or nanowires are pressed and sintered, thereafter cooled to room temperature at room temperature and finally pressing the cooled geometric shape to form the porous silver metal article of manufacture. The collected dendrites crystals or nanowires also can be pressed in a carbon based mold or, alternatively, a non-carbon based mold and in vacuum, sintered, cooled to room temperature.

  • Patent number: 10780499
    Abstract: A method for manufacturing a porous metal with enhanced ability to bond to a plastic subsequently powder feed for injection molding process provides a powder feed to an injection molding process, to form a green embryo. The green embryo is sent into a sintering furnace for high-temperature sintering to obtain a blank sintered product. A chemical reagent is applied to form pores on the sintered product. The powder feed includes first and second metal powders evenly mixed. The second metal powder has a mass percentage of about less than 10% of a total mass of the powder feed for injection molding process. The first metal powder is corrosion-resistant. The second metal powder is readily corrodible.

  • Patent number: 10773456
    Abstract: A composite body includes a bound mixture and a resin. The bound mixture includes a binder and a plurality of particles. The resin fully infiltrates the bound mixture such that the resin fully infiltrates an entire thickness of the composite body. The composite body is formed by combining a plurality of particles with a binder to form a bound mixture and infiltrating the bound mixture with a resin to a depth such that substantially an entire thickness of the composite body contains the resin.

  • Patent number: 10695978
    Abstract: The present invention relates to the technical field of 3D printing, especially in the form of the binder jetting method, in which particles in a powder bed are bonded by means of a printed adhesive to form a three-dimensional object. The particles may be inorganic particles, for example sand or a metal powder, or polymeric particulate, for example polymethacrylates or polyamides. For this purpose, polymethacrylates may take the form, for example, of suspension polymers, called bead polymers.

  • Patent number: 10688718
    Abstract: The present invention relates to the technical field of 3D printing, especially in the form of the binder jetting method, in which particulate material in a powder bed is bonded by means of a printed adhesive to form a three-dimensional object. The particulate materials may be inorganic materials, for example sand or a metal powder, or particulate polymeric materials, for example polymethacrylates or polyamides. For this purpose, polymethacrylates may take the form, for example, of suspension polymers, called bead polymers. The present invention relates to the use of porous particles in the binder jetting process, in particular of porous suspension polymers. These powders for 3-D printing differ from the prior art in that the porosity results in a faster and better absorption of the printed binder by the powder particles. A great advantage of this procedure is additionally that a product with less warpage is formed and that the end product has a better surface appearance.

  • Patent number: 10436192
    Abstract: A sliding component and its producing method are provided. The sliding component includes a base section made of steel or cast iron, and a sliding section having a sliding surface, made of copper alloy including hard particles, and joined to the base section. The hard particles in the sliding section are arranged such that those in a region including an outer periphery of the interface with the base section have their longitudinal directions coinciding with the directions along the outer periphery as compared to those in an inner peripheral side. This improves the durability of the sliding section in its region including the outer periphery of the interface with the base section.
