Improved three dimensional object obtained by means of a stereolithography process and method for the computer graphic design of said object

摘要

The invention is a three dimensional object (1) made by means of a stereolithography process comprising a plurality of supports (3) that are connected to the body (2) of the object through joining elements (4) in each one of which it is possible to identify a shaped area (5) recessed with respect to the external surface of the joining element (4) and having the bottom corner (6) that delimits a pre established fracture area (7) for the detachment of the support (3). Each one of the joining elements (4) comprises a first body (8) projecting from the external surface that delimits the body (2) of the object and a second body (9) projecting from the support (3) the bodies (8) and (9) being connected to each other so as to define the shaped area (5) whose bottom corner (6) delimits the pre established fracture area (7). Each one of the bodies (8 9) has its convex curved external surface that constitutes part of the external surface of a sphere or an ellipsoid.
