The invention relates to a 3D printing graphene-nonmetal composite material, a preparation method and application. The preparation method comprises the following steps: (1) mixing, grinding and shearing graphene quantum dots and/or graphene microchips and a nonmetal elementary substance and/or nonmetal compound to prepare a composite pulp material or composite powder material, wherein the ultrasonic frequency is 10 to 100 KHz, and the weight percent of the graphene quantum dots and/or graphene microchips is 0.01 to 30 percent; and (2) drying the prepared composite pulp material or powder material. The laser sintered graphene-nonmetal composite material and a preparation method thereof are provided for 3D printing. The composite material has excellent properties of high hardness, high strength, corrosion resistance and easiness in processing and use; and after the 3D printing, the composite can be sintered and quenched by virtue of laser to promote the compactness of particles of the composite material and to
