A method includes forming a fluid conduit inside a heat shield in an additive manufacturing process, wherein a fluid nozzle is defined at a downstream end of the fluid conduit, and wherein the heat shield is formed about the fluid nozzle. The method includes removing powder from an interior passage of the fluid conduit and fluid nozzle and from an insulation gap defined between the heat shield and the fluid conduit and fluid nozzle. The method includes separating the heat shield, fluid conduit, and fluid nozzle from the build platform. The method includes shifting the fluid conduit and fluid nozzle to a shifted position relative to the heat shield, and securing the fluid conduit and fluid nozzle to the heat shield in the shifted position.

A production method for producing a product by joining a first part containing an inorganic powder and a binder to a second part containing an inorganic powder and a binder is provided. The production method includes a first step of forming the first part by a three-dimensional shaping apparatus, a second step of forming the second part, a third step of assembling the first part and the second part, thereby obtaining an assembly, a fourth step of heating the assembly at a first temperature, and a fifth step of heating the assembly at a second temperature higher than the first temperature after the fourth step, wherein the first part has a first region that comes in contact with the second part and a second region that does not come in contact with the second part, and a melting point of the binder contained in the first region is lower than a melting point of the binder contained in the second region.

The invention relates to a method for the induction hardening of a workpiece, in particular a toothed and/or corrugated and/or ribbed workpiece such as a gear or saw blade, wherein a matchingly shaped induction loop is guided or set over the workpiece surface to be hardened, the induction loop being formed layer-by-layer by the additive application of material, and the induction loop being shaped to match the surface to be hardened.

An article of manufacture includes a part structure formed via a first additive manufacturing process and a floating structure within the part structure which is mechanically decoupled from the part structure. The floating structure is formed concurrently with the part structure via the first additive manufacturing process.

A method for connecting a first component to a second component to form an assembly forms a press fit connection between the first component and the second component, for which purpose the second component is produced having an annular component section. A recess is formed, in which the first component is at least partially arranged. At least the annular component section of the second component is produced as a sintered component and has net shape or near net shape quality at least in the region of the recess.

A manufacturing method for a three-dimensional molded object includes repeating formation of a material layer and formation of a solidified layer, the material layer being formed by spreading a metal material on a base plate and the solidified layer being formed by irradiating the material layer with a laser beam or an electron beam, thereby molding a solidified body which is a laminated solidified layer on the base plate; and subjecting the base plate and the solidified body after molding to a heat treatment.

A multi-piece part includes multiple pieces fabricated via different types of fabrication processes, wherein the multiple parts are configured to be coupled to one another to form the assembly. At least one of the multiple parts is fabricated via an additive manufacturing method. The multi-piece part also includes a holder assembly that couples and holds together the multiple pieces of the multi-piece part, wherein the holder assembly comprises a reversible, mechanical-type coupling.

The invention relates to a compacted and densified metal material having one or more phases formed of an agglomerate of grains, the cohesion of the material being provided by bridges formed between grains, said material having a relative density higher than or equal to 95% and preferably higher than or equal to 98%.
