Abstract: A powder flow monitoring system may include a computing device configured to receive image data representing illuminated powder of a powder stream between a powder delivery device and a build surface of a component, generate a representation of the powder stream based on the image data, and output the representation of the powder stream for display at a display device.

Abstract: In some examples, a system including a fluid stream monitoring system. The monitoring system includes an illumination device configured to illuminate at least some of particles suspended in a fluid stream; and an imaging device configured to image the illuminated particles at a first image plane that intersects a longitudinal axis of the fluid stream, wherein the illumination device and the imaging device are registered to the fluid stream delivery device in the first image plane, where the first image plane is substantially orthogonal to the longitudinal axis. The system includes processing circuitry configured to determine one or more physical characteristics of the fluid particles.

Abstract: An additive manufacturing system may include a powder delivery device configured to direct a powder stream toward a build surface of a component, and a powder flow monitoring system. The powder delivery device defines a longitudinal axis oriented toward the build surface. The powder flow monitoring system includes an illumination device configured to illuminate at least some powder the powder stream between the powder delivery device and the build surface; and an imaging device configured to image the illuminated powder at an image plane that intersects the longitudinal axis. The illumination device and the imaging device may be registered to the powder delivery device in a plane substantially orthogonal to the longitudinal axis.

Abstract: A system may include one or more computing devices configured to receive image data representing illuminated powder of a powder stream between a powder delivery device of an additive manufacturing system and a build surface of a component; determine at least one metric associated with the powder stream based on the received image data; determine whether the at least one metric indicates an abnormal state of the at least one metric; and cause the additive manufacturing system to perform at least one action in response to determining that the at least one metric indicates the abnormal state.
