Abstract: The invention relates to a layer building process for the additive manufacture of at least one wall region of a component including applying at least one powder layer of a material to at least one building-up and joining zone of at least one movable building platform, carrying out a first solidifying step, in which the material is irradiated selectively with at least one energy beam, wherein irradiation parameters of the at least one energy beam are set so a molten bath is produced and a defect-affected wall region of the wall is produced, without applying a further powder layer, carrying out a second solidifying step, in which the defect-affected wall region produced in the first solidifying step is irradiated selectively with the at least one energy beam, lowering the building platform layer by layer by a predefined layer thickness, and repeating the steps above one or more times.

Abstract: Disclosed is a method for providing control data for an additive manufacture device having a first step of accessing model data, and a second step of generating a data model in which a construction material layer region to be solidified during the production of an object section is specified for a construction material layer. The region to be solidified is divided into a first sub-region and a second sub-region, and a respective solidification scan of the region locations to be solidified is specified in a data model. The scan solidifying the construction material, and a repeated scan, is specified at the locations of the second sub-region but not at the locations of the first sub-region. The energy input parameter during the repeat scan is measured such that the temperature of the construction material lies above a melting temperature. The method further includes a third step of providing data models generated in the second step as control data for integrating into a control data set.

Abstract: Implementations provide cold spray additive manufacturing (“CSAM”) with gas recovery in situ in an open environment without requiring part disassembly and removal to a repair facility. Recapturing and reusing gas in an open environment reduces costs, rendering CSAM more commercially viable and efficient, and avoids risk of new damage to parts from contemporary pre-existing CSAM processes. A gas recovery nozzle attaches to a supersonic nozzle and sends used gas to a gas recovery sub-system by capturing gas that is deflected on impact with the part during CSAM. Captured gas is stored for reuse. A flexible coupling controls distance from the gas recovery nozzle to a part substrate to prevent (1) nozzle clogging; (2) stationary shock wave interference with gas flow; and (3) gas flow misdirection. The gas recovery nozzle also suppresses disruptive supersonic sounds. Implementations enable capture for later reuse of supersonically-propelled gas during in-situ CSAM in open environments.

Abstract: The present disclosure relates to a method of 3D printing a 3D printed object. The 5 method comprises printing a layer of a build material composition comprising a solution of a metal salt and a liquid carrier. An interconnected metal network is formed by reducing the metal salt in the printed build material composition. A further layer of the build material composition is printed over the interconnected metal network, and the metal salt in the further layer is reduced to form a further 10 interconnected metal network over the underlying interconnected metal network to provide a porous structure to the 3D printed object. By layering and joining interconnected metal networks one on top of another, porous regions may be constructed within the 3D printed part.
