IMPROVED COMPUTER-IMPLEMENTED METHOD FOR DEFINING THE POINTS OF DEVELOPMENT OF SUPPORTING ELEMENTS OF AN OBJECT MADE BY MEANS OF A STEREOLITHOGRAPHY PROCESS.

摘要

Computer-implemented method for defining, on a three-dimensional model of an object (1), the points of development (6) of supporting elements (7) of the object (1) during its production through a stereolithography process. The method includes the steps of defining the surfaces or portions of surfaces (2) of the object (1) whose points are oriented towards a reference plane (p); of tracing a predefined grid of points (3) on each one of the surfaces or portions of surfaces (2); of identifying, for each one of the surfaces or portions of surfaces (2), the presence of at least one local minimum point (5) with respect to the reference plane (p); of adapting, for each one of said surfaces or portions of surfaces (2), the grid of points (3) so that one of the points of the grid (3) substantially coincides with the local minimum point (5); and of identifying the points of the adapted grid (3) as points of development (6) of the supporting elements (7) for each one of said surfaces or portions of surfaces (2).
