In the aerospace industry, the "buy-to-fly" ratio is routinely used to describe the cost associated with the amount of raw materials required to produce a finished part. EBF3 based additive manufacturing has advantages of significantly shortening machining time and reducing material cost. The proposed technology offers potential to improve EBF3 performance by further shortening machining time and reducing material cost as well as improving quality. It also can be used to monitor other additive manufacturing processes such as laser based additive manufacturing. Monitoring additive manufacturing processes is important for improving product quality and reliability. Additive manufacturing has a number of applications including fabricating models, prototypes, small production runs and parts where the complexity prohibits cost effective production by other techniques. Additive manufacturing market is expected to grow at a CAGR of 13.5% from 1.8 billion in 2012 to reach $3.5 billion by 2017. In addition to monitoring additive manufacturing processes, the proposed system can be used to inspect laser processing, which is an important industrial application. Laser processing can be used for all types of metal processes (e.g. welding, cutting, annealing and drilling) and semiconductor and microelectronics manufacturing (e.g. lithography, scribing, defect repair, and surface cleaning).
