摘要： Selective laser solidification apparatus is described that includes a powder bed onto which a powder layer can be deposited and a gas flow unit for passing a flow of gas over the powder bed along a predefined gas flow direction. A laser scanning unit is provided for scanning a laser beam over the powder layer to selectively solidify at least part of the powder layer to form a required pattern. The required pattern is formed from a plurality of stripes or stripe segments that are formed by advancing the laser beam along the stripe or stripe segment in a stripe formation direction. The stripe formation direction is arranged so that it always at least partially opposes the predefined gas flow direction. A corresponding method is also described.

摘要： A coated powder for use in additive manufacturing includes a base polymer layer formed of a base polymer material and a coating polymer layer formed of a coating polymer material. At least the coating polymer material is susceptible to dielectric heating in response to electromagnetic radiation, thereby promoting fusion between adjacent particles of coated powder that are deposited during the additive manufacturing process. Specifically, when electromagnetic radiation is applied to at least an interface area between adjacent particles of coated powder, the polymer coating layer melts to diffuse across the interface area, thereby preventing formation of voids. The base polymer material and the coating polymer material also may have similar melting points and compatible solubility parameters to further promote fusion between particles.

摘要： An additive manufacturing system includes a laser array including a plurality of laser devices. Each laser device of the plurality of laser devices generates an energy beam for forming a melt pool in a powder bed. The additive manufacturing system further includes at least one optical element. The optical element receives at least one of the energy beams and induces a predetermined power diffusion in the at least one energy beam.

摘要： An electron beam installation, which is used for processing powdered material, has a powder container, which can accommodate a powder bed made of the powdered material to be processed. Furthermore, it has an electron beam generator, which is configured to direct an electron beam onto laterally differing locations of the powder bed. To reduce the dispersion of the powdered material during the processing using the electron beam, the electron beam installation has a frit device, which, by applying an AC voltage between at least two electrodes, generates an electromagnetic alternating field, which bonds the powdered material of the powder bed, at least in regions over the powder bed.

摘要： An embodiment of a method includes depositing a quantity of first intermediary material onto an electrically insulating substrate in a pattern corresponding to a desired pattern of a first conductive structure. The first intermediary material is adhered to the substrate to form a first intermediate layer to maintain the desired pattern of the first conductive structure. A quantity of a precursor of electrically conductive material is deposited generally along the pattern of the first intermediate layer. Energy is applied to enable migration and consolidation of the first electrically conductive material along the pattern of the first intermediate layer, forming a functional, electrically conductive top layer. At least one of the first electrically conductive material and its precursor has a wetting angle of less than 90° relative to the first intermediate layer, and a wetting angle greater than 90° relative to the substrate. At least one of the depositing steps is an additive deposition step.

摘要： Apparatus and methods for removing and/or destroying support structures associated with objects fabricated using additive manufacturing techniques are presented herein. Structural supports may be used during an additive manufacturing process to prevent deformation of a build piece (e.g., three dimensional (3D) printed structure). In some examples, a build piece may be manufactured such that the structural supports are internal to the completed build piece. However, removing the structural supports may reduce the weight of the build piece and reduce the amount of debris trapped within the build piece. Thus, certain aspects of the disclosure are directed to a hose including a bendable and elongated tube member as well as a fracturing member configured to fracture an internal support structure within an additively manufactured part.
