Embodiment Construction

[0052] in figure 1 The general schematic diagram in shows a three-dimensional object that is the subject of the present invention, where the three-dimensional object is represented by 1.

[0053] It can be observed that the object includes an annular body 2 having a substantially circular shape, which is provided with a plurality of supports 3 connected to the annular body 2 internally and externally.

[0054] It is important to point out that the illustrated three-dimensional object is only shown as an example of any three-dimensional object obtained by a stereolithography process and provided with a plurality of supports that hold parts of the object during the forming process.

[0055] In addition, the annular body 2 of the three-dimensional object 1 constitutes a desired model.

[0056] Since the description provided below may involve obtaining any three-dimensional object of any shape and size through a stereolithography process, it is decided to take the three-dimensional object ...

Abstract

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.

Description

Technical field [0001] The present invention relates to an improved three-dimensional object obtained by a stereolithography process, and in particular, the present invention relates to a joining element of a support that connects different parts of the object to each other. [0002] The invention also relates to a method for the computer graphics design of the object and particularly the joining element. Background technique [0003] The stereolithography technology is known as a technology that allows three-dimensional objects to be produced directly from digital data processed by CAD / CAM software. [0004] Since the stereolithography technology makes it possible to obtain even a three-dimensional object with a complex structure in a short time, which can be analyzed and tested before entering the industrial manufacturing stage, the stereolithography technology is mainly used for making prototypes. [0005] For this purpose, the stereolithography process is widely used to make a mod...
