Owing to their multiple outstanding properties including high Young‘s modulus, high specific strength, good wear resistance and high temperature durability, Ti6Al4V-based composites had broad prospects in various high-end structural application-fields such as aerospace, automotive manufacturing and petrochemical engineering. However, conventional subtractive manufacturing methods for preparation of Ti6Al4V-based composites were unable to satisfy the requirement of mass production, due to their common disadvantages including high energy consumption, low efficiency, complex processes, low material utilization ratio and the requirement of cost-intensive post treatments. In respect of this, additive manufacturing （AM） technology with a series of merits including low energy consumption, high efficiency, high material utilization ratio and the capability of near-net forming complex-shaped products, had obvious applicating advantage and important researching value in the field of preparing Ti6Al4V-based composites. This paper reviewes the present additive manufacturing methods for preparation of Ti6Al4Vbased composites, including selective laser melting （SLM）, laser directed energy deposition （LDED）, electron beam melting （EBM）, wire arc additive manufacturing （WAAM）and electron beam freeform fabrication （EBFF）, summarizes their technical principles and advantages/disadvantages,appropriate processing parameters, microscopic morphology characteristics and featuring mechanical properties of the Ti6Al4Vbased composites containing in-situ formed ceramic reinforcing phases, and outlooks the future development trends in the field of additive manufacturing Ti6Al4V-based composites.
