摘要： Additive manufacturing systems, methods, and computer readable media may be configured to perform a calibration. Calibrating an additive manufacturing system may include comparing a digital representation of one or more calibration marks to a calibration-CAD model that includes one or more model calibration marks, and applying a calibration adjustment to one or more CAD models based at least in part on the comparison. The digital representation of the one or more calibration marks may have been obtained using a vision system, and the one or more calibration marks may have been printed on a calibration surface according to the calibration-CAD model using an additive manufacturing machine. The calibration adjustment may be configured to align the one or more CAD models with one or more coordinates of the additive manufacturing system.

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： 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.
