Title: SYSTEM AND METHOD FOR ADDITIVE MANUFACTURING PROCESS CONTROL
Abstract:
A method of process control for an additive manufacturing system includes monitoring a spark plume created during manufacturing of an article, capturing at least one image of the spark plume, deriving image data from the at least one image, feeding the image data into a statistical process control module, and generating an alert if the image data exceeds pre-determined control limits.
