A Ti3C2 MXene/Ti composite powder was developed through surface modification and coating for producing a high-performance titanium matrix composites (TMCs) by laser power bed fusion. Introducing MXene rarely changed the original sphericity flowability of Ti while it slightly enhanced absorption capacity powder. The printing conditions in turn affected morphology distribution as-printed composites. At optimised parameters, majority with high structural integrity uniform remained along grain...
