The invention relates to methods of enabling fractal objects to be manufactured. In accordance with the invention, the method consists in performing repeated scaling reductions on a parent generator defined by means of three-dimensional coordinates, in storing the coordinates of each daughter object obtained by such a scaling reduction, and in repeating the scaling reduction until the dimensions of a daughter object become less than a given threshold value. The coordinates of the daughter objects are then supplied to stereolithographic apparatus which manufactures the fractal object defined by assembling together the daughter objects.

A method of manufacturing three-dimensional fractal objects, said method being characterized in that it consists in: defining a parent generator object (40, 46, 90) by means of three-dimensional data defining its outside shape; performing three-dimensional scaling reduction on the parent generator object (40, 46, 90) so as to reduce it by N, where N is an integer, said reduction supplying daughter objects (41, 42, 43, 44, 45, 46) whose positions are defined relative to said parent generator object (40, 46, 90), each of said daughter objects (41, 42, 43, 44, 45, 46) being defined by data enabling it to be situated three-dimensionally relative to said parent generator object (40, 46, 90); repeating said scaling reduction for each of said daughter objects (41, 42, 43, 44, 45, 46) obtained by each scaling reduction until the dimensions of said daughter objects obtained by reduction become less than a given threshold value (epsilon); and supplying at least part of said data enabling said daughter objects (41, 42, 43, 44, 45, 46) to be situated relative to said parent generator object (40, 46, 90) to a control device (23) for controlling stereolithographic apparatus which manufactures said fractal object.
