The invention provides a TiC ceramic with a laminated structure, and a preparation method of the TiC ceramic. The TiC ceramic with the laminated structure sequentially comprises a Ti layer, a Ti-C gradual change transition layer, a C layer, a Ti-C gradual change transition layer, a Ti layer... a Ti-C gradual change transition layer, a C layer, a Ti-C gradual change transition layer and a Ti layerfrom bottom to top. The TiC ceramic with the laminated structure has the toughness of titanium and the hardness of carbon, and has good ductility, heat resistance, wear resistance and impact resistance. According to the invention, printing is conducted layer by layer through 3D printing equipment according to the stacking sequence of the Ti layer, the C layer, the Ti layer, the C layer and the Tilayer, and an interface between the Ti layer and the C layer is subjected to rapid cold machining treatment through ultra-strong pulse energy beams or particle beams to form a Ti-C gradient transitionlayer combining the Ti layer and the C layer is formed, so that the problems of poor chemical compatibility and wettability of a titanium nano material and a carbon nano material can be solved, compounding of the titanium nano material and the carbon nano material can be well achieved, and then the TiC ceramic which is high in interface bonding and has a laminated structure is formed.
