Abstract
An additive manufacturing system is configured to manufacture a component. The additive manufacturing system includes a build platform, a recoater, a monitoring camera, and a controller. The component is disposed on the build platform. The recoater includes a recoater blade configured to spread a powdered build material across the build platform and the component forming a powder bed. The monitoring camera is positioned to image the recoater blade. The monitoring camera is configured to acquire a plurality of images of the recoater blade. The controller is configured to receive the plurality of images from the monitoring camera. The controller is configured to detect defects in the powder bed based on the plurality of images received from the monitoring camera.
