The recent research progresses on the laser additive manufacturing of HEAs were reviewed, especially in terms of forming process, element content (molar fraction), heat treatment process, and enhanced phase. Laser melting deposition (LMD) and selective laser melting (SLM) processes were compared and analyzed, and the microstructure and mechanical properties of HEAs fabricated by LMD and SLM were investigated. Finally, the development trend and the major problems of HEAs prepared by the laser additive manufacturing were point out, and the improvement measures were proposed.
