Abstract: A method of additive manufacture suitable for large and high resolution structures is disclosed. The method may include sequentially advancing each portion of a continuous part in the longitudinal direction from a first zone to a second zone. In the first zone, selected granules of a granular material may be amalgamated. In the second zone, unamalgamated granules of the granular material may be removed. The method may further include advancing a first portion of the continuous part from the second zone to a third zone while (1) a last portion of the continuous part is formed within the first zone and (2) the first portion is maintained in the same position in the lateral and transverse directions that the first portion occupied within the first zone and the second zone.

Abstract: Adjustable guide systems and additive manufacturing systems incorporating the same are disclosed. An adjustable guide system includes a first arm support coupled to a first end of a powder distributor in an additive manufacturing system, a second arm support coupled to a second end of the powder distributor opposite the first end, a plurality of shuttles, and a plurality of guide rails. Each one of the plurality of shuttles is pivotally coupled to the first arm support or the second arm support via one or more link arms. Each one of the plurality of guide rails supports a corresponding one of the plurality of shuttles thereon and allows each shuttle to move along the respective guide rail.

Abstract: A build unit for additively manufacturing three-dimensional objects may include an energy beam system having one or more irradiation devices respectively configured to direct one or more energy beams onto a region of a powder bed, and an inertization system including an irradiation chamber defining an irradiation plenum, one or more supply manifolds, and a return manifold. The one or more supply manifolds may include a downflow manifold configured to provide a downward flow of a process gas through at least a portion of the irradiation plenum defined by the irradiation chamber, and/or a crossflow manifold configured to provide a lateral flow of the process gas through at least a portion of the irradiation plenum defined by the irradiation chamber. The return manifold may evacuate or otherwise remove process gas from the irradiation plenum defined by the irradiation chamber.

Abstract: A method and an apparatus for collecting a powdered material after a print job in powder bed fusion additive manufacturing may involve a build platform supporting a powder bed capable of tilting, inverting, and shaking to separate the powder bed substantially from the build platform in a hopper. The powdered material may be collected in a hopper for reuse in later print jobs. The powder collecting process may be automated to increase efficiency of powder bed fusion additive manufacturing.

Abstract: This shaping apparatus is equipped with: a movement system which moves a target surface; a measurement system for acquiring position information of the target surface in a state movable by the movement system, a beam shaping system that has a beam irradiation section and a material processing section which supplies a shaping material irradiated by a beam from beam irradiation section; and a controller. On the basis of 3D data of a three-dimensional shaped object to be formed on a target surface and position information of the target surface acquired using the measurement system, the controller controls the movement system and the beam shaping system such that a target portion on the target surface is shaped by supplying the shaping material while moving the target surface and the beam from beam irradiation section relative to each other.

Abstract: A method of additive manufacture is disclosed. The method may include restricting, by an enclosure, an exchange of gaseous matter between an interior of the enclosure and an exterior of the enclosure. The method may further include running multiple machines within the enclosure. Each of the machines may execute its own process of additive manufacture. While the machines are running, a gas management system may maintain gaseous oxygen within the enclosure at or below a limiting oxygen concentration for the interior.

Abstract: A manipulator device such as a robot arm that is capable of increasing manufacturing throughput for additively manufactured parts, and allows for the manipulation of parts that would be difficult or impossible for a human to move is described. The manipulator can grasp various permanent or temporary additively manufactured manipulation points on a part to enable repositioning or maneuvering of the part.

Abstract: Devices, systems, and methods are directed to binder jetting for forming three-dimensional parts having controlled, macroscopically inhomogeneous material composition. In general, a binder may be delivered to each layer of a plurality of layers of a powder of inorganic particles. An active component may be introduced, in a spatially controlled distribution, to at least one of the plurality of layers such that the binder, the powder of inorganic particles, and the active component, in combination, form an object. The object may be thermally processed into a three-dimensional part having a gradient of one or more physicochemical properties of a material at least partially formed from thermally processing the inorganic particles and the active component of the object.

Abstract: A manufacturing chamber for an additive manufacturing machine comprises in an enclosure: a working plane; a manufacturing platform for the deposition of the layers of additive manufacturing material and for supporting the part being manufactured; and a circuit for circulating an inert gas flow over the manufacturing platform, characterized in that the enclosure and/or the working plane comprises an inlet opening for the gas flow, in that the working plane comprises an upstream ramp, connected to the area of the working plane where the manufacturing platform is located by a surface having a rounded convex profile, and in that the surface with a rounded convex profile is configured for attaching the gas flow, by the Coanda effect, above the working plane.
