The invention discloses a method for precisely repairing a defective face of remains based on the 3D printing technology. The method is characterized by using a full-face photo taken before death of the deceased or carrying out three-dimensional scanning on the defective face of the deceased to acquire data, generating a face three-dimensional model of the deceased by using computer three-
dimensional modeling software and importing the face three-dimensional model into a 3D printer to print a
face model, manufacturing repair materials of
silica gel and sculpture mud by taking the 3D printing model as a mold or directly using a
mask obtained through 3D printing as the repairing material, then coloring, fixing and finishing the repairing material and connecting the repairing material with the remains. Compared with a manual sculpture, the method has high vividness, the
silica gel material has touch feeling of
skin and is vivid in appearance; in particular, the time for which a remains cosmetic designer faces the remains can be shortened, and the safety and
sanitation risks for the remains cosmetic designer can be reduced; and meanwhile, the
automation degree of face repairing is improved.
