Metal additive manufacturing technology is an advanced manufacturing technology developed from the early 1990s, which can realize the non-die, fast, fully dense near-net forming of complex high-performance structural metal parts. W-Ni-Fe heavy alloys are widely used in defense industry and national economy due to their properties of high density, high strength and high plasticity. In recent years, the additive manufacturing of W-Ni-Fe heavy alloys has attracted extensive attention. This paper summarizes the research progress of additive manufacturing of W-Ni-Fe heavy alloys from domestic and foreign research institutions, which use selective laser melting (SLM), laser melting deposition (LMD), electron beam selective melting (EBSM) and binder jet printing (BJP) to prepare W-Ni-Fe heavy alloys. The forming process, microstructure and mechanical properties of the additive manufactured parts are analyzed. The research trends are finally speculated.
