Methods for additively manufactured identification features
Techniques for integrating a machine-readable matrix with a component of a mechanical structure using three-dimensional (3-D) printing are disclosed. Such techniques include generating at least one data model representing the component, and projecting a matrix pattern identifying one or more features of the component onto a selected surface portion of the component to produce a modified data model for use as an input to a 3-D printer.
1. A method of integrating a machine-readable matrix with a component of a mechanical structure using three-dimensional (3-D) printing, comprising:
generating at least one data model representing the component; and
projecting a matrix pattern identifying one or more features of the component onto a selected surface portion of the component to produce a modified data model for use as an input to a 3-D printer, wherein projecting the matrix pattern comprises integrating a 3-D matrix pattern into the selected surface to produce the modified data model, and wherein integrating the 3-D matrix pattern into the selected surface comprises selectively eliminating material below the selected surface to form the 3-D matrix pattern.
2. The method of claim 1 , further comprising 3-D printing the component including the projected matrix pattern using the modified data model.
3. The method of claim 1 , wherein the projecting the matrix pattern comprises at least one of translating, scaling, and rotating the matrix pattern relative to the selected surface portion.
4. The method of claim 1 , wherein the projecting the matrix pattern comprises converting a two-dimensional (2-D) matrix pattern into a 3-D matrix pattern on the selected surface portion.
5. The method of claim 1 , further comprising adding a plurality of surface textures to the matrix pattern.
6. The method of claim 1 , further comprising varying an elevation of selected portions of the matrix pattern to create a machine-readable contrast.
7. The method of claim 6 , wherein at least one elevated portion appears brighter to a machine reader and at least one portion lower than the at least one elevated portion appears darker to the machine reader to thereby create the machine-readable contrast.
8. The method of claim 1 , further comprising adding coloration to the matrix pattern.
9. The method of claim 1 , further comprising adding an infill to the matrix pattern.
10. The method of claim 1 , further comprising 3-D printing the component using the modified data model.
11. A method of integrating a machine-readable matrix with a component of a mechanical structure using three-dimensional (3-D) printing, comprising:
generating at least one data model representing the component; and
projecting a matrix pattern identifying one or more features of the component onto a selected surface portion of the component to produce a modified data model for use as an input to a 3-D printer, wherein projecting the matrix pattern comprises integrating a 3-D matrix pattern into the selected surface to produce the modified data model, and integrating the 3-D matrix pattern into the selected surface comprises selectively adding material above the selected surface portion to form the 3-D matrix pattern.
12. The method of claim 11 , further comprising 3-D printing the component including the projected matrix pattern using the modified data model.
13. The method of claim 11 , wherein the projecting the matrix pattern comprises at least one of translating, scaling, and rotating the matrix pattern relative to the selected surface portion.

15. The method of claim 11 , further comprising adding a plurality of surface textures to the matrix pattern.
16. The method of claim 11 , further comprising varying an elevation of selected portions of the matrix pattern to create a machine-readable contrast.
17. The method of claim 16 , wherein at least one elevated portion appears brighter to a machine reader and at least one portion lower than the at least one elevated portion appears darker to the machine reader to thereby create the machine-readable contrast.
18. The method of claim 11 , further comprising adding coloration to the matrix pattern.
19. The method of claim 11 , further comprising adding an infill to the matrix pattern.
