摘要： A tooling assembly for mounting a plurality of components, such as compressor blades, in a powder bed additive manufacturing machine to facilitate a repair process is provided. The tooling assembly includes component fixtures configured for receiving each of the compressor blades, a mounting plate for receiving the component fixtures, and a complementary fixture defining a plurality of voids within which the compressor blades are received when the complementary fixture is mounted to the mounting plate such that less powder is required to fill the powder bed.

摘要： An additive manufacturing machine includes a build platform being movable along a build direction and a powder supply assembly for dispensing additive powder above a build plane. A recoating assembly is used for spreading the additive powder into a build layer on the powder bed. The recoating assembly includes a support beam that slidably supports a recoater blade and moves along a recoater direction over the powder bed. A blade positioning mechanism adjusts the vertical position of the recoater blade in response to measurements from a sensing device which measures a tip clearance between the recoater blade and the build plane. The tip clearance may be measured along the length of the recoater blade while stationary and while moving along the recoater direction to obtain a smooth and level layer of additive powder.

摘要： Methods of additively printing an extension segment on a workpiece may include pretreating a workpiece-interface of a workpiece using an energy beam from an additive manufacturing machine, providing a pretreated workpiece-interface having received a pretreatment, with the pretreatment remediating an aberrant feature of the workpiece and/or the workpiece-interface. Such methods may additionally include additively printing an extension segment on the pretreated workpiece-interface using the energy beam from the additive manufacturing machine. Exemplary additive manufacturing system for printing an extension segment on a workpiece may include a controller operably coupled to a vision system and an additive manufacturing machine.

摘要： An additive manufacturing system may include a controller operably coupled to a vision system and an additive manufacturing machine. The controller may be configured to determine a workpiece-interface of each of a plurality of workpieces from one or more digital representations of one or more fields of view having been captured by a vision system and determining one or more coordinates of the workpiece-interface of respective ones of the plurality of workpieces, and to transmit one or more print commands to an additive manufacturing machine so as to additively print a plurality of extension segments on the workpiece-interface of respective ones of the plurality of workpieces, with the one or more print commands having been generated based at least in part on the one or more digital representations of the one or more fields of view.

摘要： An additive manufacturing machine for repairing a component includes a build platform that supports the component and a powder dispensing assembly for selectively depositing additive powder over the build platform. A powder seal assembly includes a powder support plate positioned above the build platform and defining an aperture for receiving the component without contacting the component. A clamping mechanism is movable relative to the powder support plate and defines a void for receiving a resilient sealing element around the aperture. An actuating mechanism, such as bolts or a linear actuator, moves the clamping mechanism toward the powder support plate to deform the resilient sealing element until the resilient sealing element contacts and forms a seal with the component.

摘要： An additive manufacturing machine for repairing a component includes a build platform that supports the component and a powder dispensing assembly for selectively depositing additive powder over the build platform. A powder seal assembly includes a powder support plate positioned above the build platform and defining an aperture for receiving the component without contacting the component. An inflatable sealing element is operably coupled to the powder support plate around the aperture and is inflated to contact and seal against the component, thereby forming a support surface above the build platform upon which additive powder may be deposited.

摘要： An additive manufacturing system is configured to manufacture a component. The additive manufacturing system includes a laser device, a build platform, a first scanning device, and an air knife. The laser device is configured to generate a laser beam. The component is disposed on the build platform. The air knife is configured to channel an inert gas across the build platform. The first scanning device is configured to selectively direct the laser beam across the build platform. The laser beam is configured to generate successive layers of a melted powdered build material on the component and the build platform. The build platform is configured to rotate the component relative to the air knife.
