The method for making the topographical mould comprises a process of printing contour lines on a number of 0.5mm thick base plates; a process of cutting the printed base plates according to the contour lines; a process of bonding the cut plate on the correspondent positions of the lowest base plate; making a mould by covering rubber latex on the surface of the bonded plates, solidifying the latex into a rubber layer, and covering plaster over the rubber layer. The rubber layer prevents the bonded plates from disforming or harming. The method provides economical and precise mould.
