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 .
