摘要

Method for generating a numerical representation of a three-dimensional object (11) to be made through stereolithography, comprising the following operations: preparing a first set of data (1) representative of the geometry of the object (11); defining first surfaces (13, 13a) of the object (11) and reference surfaces (14, 14a) facing them; defining a first point (X1) on the first surface (13, 13a), a second point (X2) on the corresponding reference surface (14, 14a) and geometric parameters (P1 . . . Pn) that define the three-dimensional geometry of a corresponding supporting element (15) that connects the first point (X1) to the second point (X2); generating a third set of data (3) containing the coordinates (7) of the first point (X1) and of the second point (X2) and the values (8) of the geometric parameters (P1 . . . Pn) of each supporting element (15); generating a numerical representation of each supporting element (15) based on the third set of data (3); calculating a second set of data (2) representative of the geometry resulting from the union of the object (11) with the supporting elements (15).
