Duplicating method of painted sculpture

The invention discloses a duplicating method, and particularly discloses a duplicating method of painted sculpture. The method comprises the following steps of utilizing paint software for manufacturing a two-dimension series or four-dimension series relief pattern, and forming a relief model; utilizing the software for duplicating the relief model into a relief mold; inputting the relief mold into a carving machine, carving the pattern on the wood, and forming a wood mold; pouring clay slurry into the wood mold, and placing the poured clay slurry on the ventilation position for natural withering, taking the dried clay slurry from the wood mold, and completing duplicating. A computer is adopted in the method for precisely drawing, the mold is generated, the carving machine is used for performing carving, the manual mold manufacturing process is removed, the process is simple, the working efficiency is high, the carved mold can be repeatedly used, and the cost is greatly reduced.
