METHOD AND EQUIPMENT FOR GENERATING A NUMERICAL REPRESENTATION OF A THREE DIMENSIONAL OBJECT SAID NUMERICAL REPRESENTATION BEING SUITED TO BE USED FOR MAKING SAID THREE DIMENSIONAL OBJECT THROUGH STEREOLITHOGRAPHY

摘要

Computer implemented 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 corresponding first point (X1) on the first surface (13 13a) a corresponding second point (X2) on the corresponding reference surface (14 14a) and corresponding 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).
