Distortion Analysis in Thin-Wall Repairing via Directed Energy Deposition

The goal of this thesis is the evaluation of the applicability of the Additive Manufacturing technology in the repairing process of Automotive thin layer frame panels. Most specifically the adopted technology for this study is the Directed Energy Deposition (DED), an Additive Manifacturing technique that is suitable for the repairing processes of metal components. The implementation of the DED in this study is crucial to understand the applicability of this technology to repair damaged car panels with respect the complete substitution of them. This allows to reduce costs and optimize at the same time the entire repairing process. In the thesis metal ribs repaired with DED technology are analysed in order to evaluate the correlation between deposition parameters and obtained results. The experimental tests and analysis were conducted in IAM@Polito laboratories and Reverse Engineering Lab of the Politecnico di Torino. This analysis and study conducted by me represent a part of a university project called Mics Project (Made in Italy Circolare e Sostenibile).
