 The circular economy is an economic model which seeks to reduce waste by keeping resources in use for as long as possible. This can be achieved through repair and remanufacturing of products, components and materials. Directed energy deposition, DED, is a form of additive manufacturing, AM, which is particularly suited to repairing and remanufacturing automotive and aerospace components. It offers several benefits compared to traditional welding methods such as lower heat input, warpage and distortion, higher cooling rates, lower dilution rates, excellent metallurgical bonding between the deposited layers, high precision and suitability for full automation. As a result, DED is a promising technique for repairing and remanufacturing components. This article was authored by Abdullah Sabri, Alberta Aversa, Julio Marchese and others.
