Remanufacturing of parts using additive processes. Case Studies

Abstract

The remanufacturing process is placed in the worldwide context of circular economy and is used for different consumer goods or industrial products. In the remanufacturing process the Reverse Engineering technique and Additive Manufacturing processes play an important role because of their flexibility in designing and manufacturing. In the Department of Manufacturing Engineering, “Transilvania” University of Brasov, using these technique and processes, have been developed different case studies. In this paper, are presented three case studies: how a damaged gear from a collection sewing machine is redesigned and remanufactured, using selective laser melting process, how are (re)manufactured human teeth using selective laser melting process and how a damaged gear from a fishing reel is redesigned and remanufactured using polyjet technology.
