NOVELTY - Preparing graphene-reinforced porous titanium composite material comprises (i) adding the graphene and spherical titanium powder into a ball milling tank, adding alcohol for ball milling and mixing and heating and drying the ball-milled mixture to obtain graphene/titanium composite powder; (ii) designing a controllable porous structure model using the solid Works software, layering using the layering software, introducing into the forming device, adding the graphene/titanium composite powder into the sample feeder in the device, using argon as the inert protective gas, where the oxygen content is less than 0.02%, preheating the substrate and using Concept Mlab cusing R laser to melt three-dimensional printed porous titanium; and (iii) using linear cutting method to cut the formed porous titanium from the substrate. USE - The method is useful for preparing graphene-reinforced porous titanium composite material. ADVANTAGE - The method: is easy to control, fast and energy-saving; and produces the composite material with uniform grain shape, uniform size, rich hole structure and aperture, uniform hole shape, compressive strength, hardness and corrosion resistance and excellent comprehensive performance which can satisfy application requirement of porous titanium material.
