Metal Wire Additive Manufacturing: A Comparison between Arc Laser and Laser/Arc Heat Sources

In this paper, the authors introduce reader to state of art Metal Wire Additive Manufacturing (MWAM) and provide a comparison between Arc (WAAM), Laser (WLAM), Hybrid Deposition (LAHWD) based on their characteristics potential future applications, since MWAM is expected have promising in various areas, such as aerospace, automotive, biomedical, energy fields. A detailed discussion benefits drawbacks each process can help improve our understanding unique metal wire application. Therefore, paper offers comprehensive analysis that serve reference for upcoming industrial projects research initiatives, with aim helping industries choose most appropriate WAM technique specific applications.
