摘要： An additively manufactured non-uniform porous material in-situ with dense material for the in situ additive manufacturing of both porous and dense material in the same part so that no secondary process is required. The additively manufactured non-uniform porous material in-situ with dense material generally includes additively manufactured porous material which can be tuned for porosity and density, has the ability to be built in situ with dense material, and can also be tuned for response to pressure waves. Also included are computer program products, methods and components and systems manufactured using the methods.

摘要： 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.

摘要： A three-dimensional structure is formed when layers of a material are deposited onto a substrate and scanned with a high energy beam to at least partially melt each layer of the material. Upon scanning the layers at predetermined locations at least a first segment overlapping a second segment and underlapping a third segment is formed.

摘要： A technique for improving cold spray deposition conditions for cold spray additive manufacture of parts involves providing an in-situ temperature feedback controller with a remote instantaneous temperature sensor supplying surface temperature measurements of the deposition surface, and a (preferably long pulse) laser for heating. Temperature feedback allows for control over deposition conditions yielding predictable deposition properties.

摘要： A method, in accordance with one embodiment, includes forming an array of structures from a raw material via cold spray. Each of the structures is characterized by having a defined feature size in at least one dimension of less than 100 microns as measured in a plane of deposition of the structure, at least 90% of a theoretical density of the raw material, and essentially the same functional properties as the raw material. A method, in accordance with another embodiment, includes positioning a mask between a cold spray nozzle and a substrate, and forming a structure on the substrate by cold spraying a raw material from the cold spray nozzle. The structure has a shape corresponding to an aperture in the mask.

摘要： Embodiments of the systems can be configured to receive electromagnetic emissions of a substrate (e.g., a build material of a part being made via additive manufacturing) by a detector (e.g., a multi-spectral sensor) and generate a ratio of the electromagnetic emissions to perform spectral analysis with a reduced dependence on location and orientation of a surface of the substrate relative to the multi-spectral sensor. The additive manufacturing process can involve use of a laser to generate a laser beam for fusion of the build material into the part. The system can be configured to set the multi-spectral sensor off-axis with respect to the laser (e.g., an optical path of the multi-spectral sensor is at an angle that is different than the angle of incidence of the laser beam). This can allow the multi-spectral sensor to collect spectral data simultaneously as the laser is used to build the part.
