Abstract
A moire contour map of a three-dimensional object is obtained by a moire contour measuring system. The moire contour map is used for making a profiling model to be used in a profiling machine to make a number of plates having configurations corresponding to the contour lines of the moire contour map. The number of plates prepared by the profiling machine are stacked to form a stack of plates having a contour approximately equivalent to the contour of the original three-dimensional object. The stacked plates are bound together and a surface smoothing cover or a filling agent is applied on the surface of the stacked plates to form a replica of the object.
