Integrated manufacturing of REciclable multi-material COmposites for the TRANSport sector
Method of mapping melt pattern during directed energy fabrication
A method and system are provided for mapping a melt pattern of material created during directed energy fabrication. An infrared camera and a video camera are provided to record images of the pattern of melted material. Each frame of the infrared camera's images is processed to generate a first map of pixels identifying pixels indicative of a highest temperature greater than or equal to a liquidus temperature of the meltable material. Each frame of the video camera's images is processed to generate a second map of pixels identifying pixels indicative of a highest temperature greater than or equal to the liquidus temperature of the meltable material. The first map of pixels and said second map of pixels are overlaid on each other wherein a third map of pixels is generated and is indicative of a hybrid image of the pattern of melted material.
