Abstract
Devices, systems, and methods for monitoring a powder layer in additive manufacturing are disclosed. A method of monitoring a powder layer includes receiving image data corresponding the powder layer supported by a powder bed within a build chamber from imaging devices, determining leading and trailing regions of interest located adjacent to a leading end and a trailing end of the moving powder distributor, respectively, the leading and trailing regions of interest moving according to movement of the moving powder distributor, selecting at least one point located in the leading region of interest from the image data, determining first characteristics of the point, when the point is located within the trailing region of interest, determining second characteristics of the point, and comparing the first characteristics to the second characteristics.
