Abstract

Advanced manufacturing technologies, including additive manufacturing, smart casting, process optimisation and hybrid manufacturing, to produce metal parts with complex non-line-of-sight structures is a revolution to the manufacturing sector. Such methods allow for products with high integrity to be manufactured with less waste material, lower cost and reduced manufacturing time. However, the methods available to non-destructively evaluate advanced manufactured components are not established. The inspection of large and dense components is challenging, particularly for complex product shapes intrinsic to many additive manufacturing and casting activities. Common inspection approaches still rely on destructive methods that are expensive and hard to implement on production lines. This paper is a cross-disciplinary review of the state-of-the-art non-destructive measuring techniques relevant to advanced manufacturing of metallics at larger length-scales, especially the use of high energy X-ray computed tomography (XCT) with a source energy of greater than 400 kV. The technologies considered as potential high energy X-ray sources include both conventional X-ray tubes, linear accelerators, and alternative technologies such as inverse Compton scattering sources, synchrotron sources and laser-driven plasma sources. Their technology advances and challenges are elaborated on. The paper also outlines the development of XCT for dimensional metrology and future needs.
