DETAILED DESCRIPTION OF INVENTION

[0030] Below, identical reference numerals denote identical or similarly formed components.

[0031] FIG. 1 depicts a component 1, on the component surface 2 of which a code 3 according to a first embodiment of the present invention is arranged in a functionally non-relevant area, which contains information acting as an identifier of the component 1, and additional information which in particular relates to the production requirements of the component, in order thereby to enable component tracking which is as exact as possible. The code 3 is produced as one piece with, and from, the same starting material as the component 1, and comprises a plurality of three-dimensionally designed code elements 4 which are arranged in the manner of a QR code in a NM matrix, wherein N corresponds to the number of rows, and M corresponds to the number of columns. Presently, N=12 and M=12 are chosen, such that collectively, a square matrix results. The code elements 4 depict the encoded data in a binary format, using raised areas and non-raised areas with reference to a reference plane defined by the component surface 2, wherein the raised areas respectively have the form of a pyramid having four tapering side walls. Each code element 4 is formed either by a single raised area or by a single non-raised area within the reference plane. Owing to the pyramidal shape of the raised areas, the light reflection behavior of the raised areas is to be clearly distinguished from that of the non-raised areas, whereby the machine readability of the code 3 is fostered. For performing a readout, for example, a smartphone having an integrated camera and corresponding software, or a comparable readout system, may be used, as for reading out a QR code.

[0032] FIG. 2 depicts a component 1, on the component surface 2 of which a code 3 according to a second embodiment of the present invention is arranged in a functionally non-relevant area. Said code differs from the code depicted in FIG. 1 only in that each code element is formed either by means of nine raised areas arranged in a square submatrix, or by means of a single non-raised area within the reference plane, the area of which corresponds to the area of nine raised areas in a square arrangement. This is advantageous in that the contrast between the code elements 4 made up of raised areas and the code elements 4 respectively made up of a non-raised area becomes clearer, thus favoring the machine readability of the code 3. At this point, it should be mentioned that, instead of nine raised areas per code element 4, a different number of raised areas arranged in a regular matrix may also generally be used per code element 4, which corresponds to an integer square number, i.e., 4, 16, 25, . . . raised areas.

[0033] FIG. 3 depicts a component 1, on the component surface 2 of which a code 3 according to a third embodiment of the present invention is arranged in a functionally non-relevant area. Said code differs from the code 3 depicted in FIG. 1 only in that, instead of pyramidal raised areas, such areas are provided which are pyramidally recessed with respect to the reference plane defined by the component surface 2. Likewise, an arrangement analogous to FIG. 2 is conceivable, having recessed areas instead of raised areas.

[0034] FIG. 4 depicts a component 1, on the component surface 2 of which a code 3 according to a fourth embodiment of the present invention is arranged in a functionally non-relevant area. Said code differs from the code 3 depicted in FIG. 1 only in that conical raised areas are provided instead of pyramidal raised areas. Even if this is presently not depicted, each code element 4 may comprise a number of raised areas which are arranged in a square submatrix, analogously to FIG. 2, and which correspond to an integer square number, i.e., 4, 9, 16, 25 . . . raised areas. Likewise, the raised areas may be replaced by recessed areas, analogously to FIG. 3.

[0035] FIG. 5 depicts a component 1, on the component surface 2 of which a code 3 according to a fifth embodiment of the present invention is arranged in a functionally non-relevant area. Said code differs from the code 3 depicted in FIG. 1 only in that spherical segment-shaped raised areas are provided instead of pyramidal raised areas. Even if this is presently not depicted, each code element 4 may comprise a number of raised areas which are arranged in a square submatrix, analogously to FIG. 2, and which correspond to an integer square number, i.e., 4, 9, 16, 25 . . . raised areas. Likewise, the raised areas may be replaced by recessed areas, analogously to FIG. 3.

[0036] The components depicted in FIGS. 1 to 5 are characterized in that the codes 3 are respectively produced as one piece with said components, such that the codes 3 cannot be easily separated from the component 1 or manipulated. The three-dimensional codes 3 arranged in the manner of a QR code can contain a large amount of information and are machine-readable in a simple manner.

[0037] FIG. 6 schematically depicts a method according to an embodiment of the present invention, via which one of the components 1 depicted in FIGS. 1 to 5, including its code 3, can be produced in series.

[0038] In a step S1, using a computer, a 3D-CAD data set is created which images the component 1 including the code 3, and which can be processed on an additive production machine. The 3D-CAD data set comprises data defining the geometry of the component, data relating to the position of the code on the component surface, and data relating to the geometry of the code, or is made up of these data.

[0039] In a second step S2, the component 1 and the code 3 are produced layer by layer on an additive production machine, on the basis of the 3D-CAD data set created in step S1.

[0040] In a step S3, a new 3D-CAD data set is created for the next of the components 1 to be produced in series, including the associated code 3. Here, the data defining the geometry of the component and the data of the 3D-CAD data set created in step S1 relating to the position of the code on the component surface are adopted, and only the data relating to the geometry of the code are replaced by new data.

[0041] In a step S4, the component 1 and the code 3 are then produced layer by layer on an additive production machine, on the basis of the 3D-CAD data set created in step S3.

[0042] Steps S3 and S4 are then repeated as a function of the number of components 1 to be produced in series.

[0043] The previously described method is characterized in that the component 1 and the associated code 3 can be produced in a single operation. A permanently correct assignment of the component 1 and the code 3 can thus always be ensured.

[0044] Alternatively, in step S1, using a computer, a 3D-CAD data set is created which images the component 1 and the position of the code 3 on the component 1, and which can be processed on an additive production machine. The 3D-CAD data set thus comprises data defining the geometry of the component and data relating to the position of the code on the component surface, or is made up of these data. Furthermore, in step S1, data relating to the geometry of the code 3 are added to this created 3D-CAD data set by means of CAM software.

[0045] In a second step S2, the component 1 and the code 3 are produced layer by layer on an additive production machine, on the basis of the data created in step 1.

[0046] In step S3, modified data relating to the geometry of the code 3 are added to the 3D-CAD data set from step 1 by means of CAM software.

[0047] In step S4, the component 1 and the code 3 are then produced layer by layer on an additive production machine on the basis of the data created in step S3.

[0048] Steps S3 and S4 are then repeated as a function of the number of components 1 to be produced in series.

[0049] Although the present invention has been illustrated and described in greater detail via the exemplary embodiment, the present invention is not limited by the disclosed examples, and other variations may be derived from it by those skilled in the art, without departing from the protective scope of the present invention.
