Abstract

A method of customizing a vehicle body includes inputting a selected customized embellishment to a laser controller, directing a beam of the laser onto a surface of the vehicle body, and guiding the beam of the laser with the laser controller to impart the selected customized embellishment to the surface.

First claim

What is claimed is:

1. A method of customizing a vehicle body comprising:
inputting a selected customized embellishment to a laser controller;
directing a beam of a laser onto a surface of the vehicle body; and
guiding the beam of the laser with the laser controller to impart the selected customized embellishment to the surface,
wherein the surface of the vehicle body includes a painted surface comprising a first layer of paint having a first color, a second layer of paint having a second color, and a third layer having a third color,
wherein the first, second, and third colors are different from each other,
wherein the first layer of paint is on the second layer of paint and the second layer of paint is on the third layer of paint,
wherein the guiding the beam of the laser with the laser controller comprises:
moving the beam of the laser along the surface of the vehicle body,
controlling a penetration depth of the beam of the laser at a first portion of the surface of the vehicle body to penetrate the first layer of paint and remove the first layer of paint to expose the second layer of paint having the second color, and
controlling the penetration depth of the beam of the laser at a second portion of the surface of the vehicle body to penetrate the first and second layers of paint and remove the first and second layers of paint to expose the third layer of paint having the third color.

2. The method of claim 1 , wherein the vehicle further comprises an unpainted surface, and the method further comprises directing the beam of the laser onto an unpainted surface to create the selected customized embellishment.

3. The method of claim 2 , further comprising forming a pattern replicating tool marks on the unpainted surface with the beam of the laser.

4. The method of claim 3 , wherein the pattern replicating the tool marks comprises a pattern that would be made by an angle grinder.

5. The method of claim 2 , further comprising controlling one of an intensity of the beam of the laser and incident angles of the beam of the laser to generate a color change in the unpainted surface.

6. The method of claim 1 , wherein the beam of the laser is controlled at the first portion to penetrate the painted surface a first depth that is equal to or greater than a thickness of the first layer of paint.

7. The method of claim 6 , wherein the beam of the laser is controlled at the second portion to penetrate the painted surface a second depth that is equal to or greater than the combined thickness of the first and second layers of paint.

8. The method of claim 1 , wherein the painted surface further comprises a fourth layer of paint disposed on the first layer of paint.

9. The method of claim 8 , wherein the fourth layer of paint is a clear coat.

10. The method of claim 9 , wherein the beam of the laser is controlled at the first portion to penetrate the painted surface a depth that is equal to or greater than a combined thickness of the fourth and first layers of paint.

11. The method of claim 9 , wherein the beam of the laser is controlled at the second portion to penetrate the painted surface a depth that is equal to or greater than a combined thickness of the fourth, first, and second layers of paint.

12. The method of claim 1 , wherein the painted surface further comprises a fourth layer of paint, the third layer of paint being disposed on the fourth layer of paint.

13. The method of claim 12 , wherein the fourth layer is a paint primer.

14. The method of claim 1 , wherein the laser controller comprises a central processing unit, a non-volatile memory, and a laser control module.

15. The method of claim 14 , wherein the beam of the laser is controlled via the laser control module.

16. The method of claim 14 , wherein a pattern of the selected customized embellishment is stored on the non-volatile memory.

17. The method of claim 1 , further comprising receiving an input from a consumer indicating the selected customized embellishment.

18. The method of claim 17 , further comprising providing different designs of customized embellishments to the customer and receiving one of the designs selected by the consumer as the selected customized embellishment.

19. The method of claim 17 , wherein the receiving the input from the customer comprises receiving a design provided by the consumer as the selected customized embellishment.
