A method of metal additive manufacturing, including forming a three-dimensional object as a successive series of layers. At least some of the successive layers is formed by depositing a layer of build material powder on a work surface, depositing a predetermined pattern of fugitive fluid and depositing a predetermined pattern of binder fluid, wherein the predetermined pattern of fugitive fluid improves at least one characteristic of the three-dimensional part.

A device includes a coater, a dispenser, and a treatment portion. The coater is to coat, layer-by-layer, a build material relative to a build pad to form a 3D object. The dispenser is to at least dispense a fluid including a first at least potentially electrically conductive material. In at least some selected locations of an external surface of the 3D object. The treatment portion is to treat the 3D object to substantially increase electrically conductivity on the external surface of the 3D object at the at least some selected locations.

A burner module according to the invention comprises at least three or four or five or six or seven or eight functional walls which delimit at least one first functional space and form a module body, wherein the module body has at least three or four or five or six or six or seven gas passage openings and at least two of these gas passage openings are connected to one another communicatively via the first functional space, and wherein at least one nozzle device having a fuel gas opening is formed in an upper wall of the burner module, which fuel gas opening is connected communicatively to the first functional space via a gas channel. The burner module is produced in an additive manner.

A process for the manufacture of a metal component, wherein, in a first step, a raw metal component (A) with auxiliary structures (E) is produced by additive manufacture by applying metal powder to a building board (D) in an installation space, the metal powder being made into the raw metal component (A) by selective laser or electron beam melting, wherein the raw metal component (A) is attached to the building board (D) by means of anchor structures (B), wherein, in a second step, the raw metal component (A) attached to the building board (D) with the anchor structures (B) is subsequently removed from the installation space and then the raw metal component (A) attached to the building board (D) by means of anchor structures (B) is subjected to a chemical, electrochemical or chemical and electrochemical post-treatment to remove the auxiliary structures, whereupon the anchor structures (B) are mechanically removed in a third step.
