3 METHOD FOR PRODUCING A THREE-DIMENSIONAL OBJECT BY MEANS OF A STEREOLITHOGRAPHY PROCESS INCLUDING A COMPUTER GRAPHIC DESIGN OF SAID OBJECT

摘要

The invention relates to a three-dimensional object (1) made by a stereolithography process, the object comprising a plurality of supports (3), connected to the body (2) of the object via a connecting element (4) (5) having a lower corner (6) defining the predetermined fracture zone (7) for the separation of said support part (3) and entering concave on the outer surface of said connection element (4) It is possible to do. Each one of the connecting elements 4 comprises a first body 8 protruding from an outer surface which defines a body 2 of the object and a second body 9 protruding from the support 3, (6) are interconnected to define a shape region (5) defining a predetermined fracture region (7). Each one of the bodies 8, 9 has a convex curved outer surface that constitutes part of the outer surface of the sphere or ellipsoid.
