Executive Summary : | Additive Manufacturing (AM) is a revolutionary technology which produces components directly from 3D data, layer-by-layer. It is possible to manufacture parts with geometries which are difficult to produce by other conventional technologies. While AM is beginning to revolutionize the aerospace manufacturing industry, one of the largest barriers to broader adoption of AM for producing aerospace parts is the lack of a “Standardized Qualification Process” that includes fully characterized process definition, developing in situ process monitoring, sensing and quantifying of the drivers of manufacturing variability in AM production parts. In-situ process monitoring sensors enable one to “certify as you build”. NDE is technique for Inspection, testing or evalaution of materials, component or assemblies for discountinuities or difference charactersatics without destroying for servicebility of the part or component. NDE like Ultrasonic , Radiography, Computed tomography etc.have to be adopted for real time in- process monitoring to insure proper Quality Assurance and Control activities for defect free space component. Moreover such techniques are required to understand the physics of failure of Electromechnaical assemblies.Currently there are no universally accepted or commercially available IQIs for industrial NDE. |
