According to one embodiment of the present invention, a method for manufacturing thin film heaters includes an automated process for applying at least one layer of ink to a conductive substrate, and forming at least one electrically conductive electrode in electrical communication with the substrate by curing the ink. When an electrical current is applied to the thin film heater, current flowing through the substrate generates heat in the substrate. In alternate embodiments, a flexographic printing process is used to overlay two similar layers of ink on a carbon impregnated substrate and cure the ink to form at least one electrode conductor.

What is claimed is: 1. A method for manufacturing a flexible heater, comprising: providing a supply of flexible and electrically conductive substrate; providing a liquid ink; advancing said substrate to a first printing location; applying a first layer of said ink in a first pattern to said substrate at the first printing location; partially curing said first layer of ink with heat; advancing said substrate to a second printing location different from the first printing location; applying a second layer of said ink in a second pattern to said substrate at the second printing location, wherein said second layer of ink substantially overlies the first layer of ink; forming at least one electrically conductive electrode by fully curing said first and second layers of ink with heat, wherein the at least one electrically conductive electrode is in electrical communication with said substrate; and forming a flexible heater, wherein said substrate generates heat as electrical current flows from said at least one electrode and through said substrate. 2. The method of claim 1, further comprising severing said substrate into at least two separated portions. 3. The method of claim 1, wherein said first and second patterns are substantially identical. 4. The method of claim 1, wherein said supply of substrate is wound in a coil. 5. The method of claim 1, wherein said partially curing and said fully curing are performed by at least one heat lamp. 6. The method of claim 1, further comprising: attaching electrical wires to at least said second layer of cured conductive ink, wherein the wires are in electrical communication with at least said second layer of cured conductive ink. 7. The method of claim 6, further comprising: generating an electrical current flowing between said substrate and said at least one electrode; and generating heat in said substrate due to a resistance in said substrate. 8. The method of claim 6, further comprising: attaching the electrical wires to an automobile electrical system. 9. The method of claim 1, wherein said supply of substrate comprises carbon impregnated polyimide film. 10. The method of claim 1, wherein: said applying a first layer of said ink in a first pattern to said substrate at the first printing location includes using a flexographic printing technique; and said applying a second layer of said ink in a second pattern to said substrate at the second printing location includes using a flexographic printing technique. 11. The method of claim 10, further comprising perforating said substrate into at least two separable portions. 12. The method of claim 10, wherein said first and second layers of ink are printed in substantially identical patterns. 13. The method of claim 10, wherein said supply of substrate is wound in a coil. 14. The method of claim 10, wherein said advancing said substrate to a first printing location and said advancing said substrate to a second printing location each further include advancing said substrate at approximately fifty (50) feet per minute with respect to the first and second printing locations. 15. The method of claim 1, further comprising: providing at least one anilox roll; wherein said applying a first layer of said ink in a first pattern to said substrate at the first printing location includes using the at least one anilox roll; and wherein said applying a second layer of said ink to said substrate at the second printing location includes using the at least one anilox roll, and said second layer of ink substantially overlies said partially cured first layer of ink. 16. The method of claim 15, further comprising perforating said substrate into at least two separable portions. 17. The method of claim 16, wherein said first and second layers of ink are printed in substantially identical patterns. 18. The method of claim 17, wherein said partially curing and said fully curing are performed by at least one heat lamp. 19. The method of claim 18, wherein said supply of substrate is wound in a coil. 20. The method of claim 19, further comprising: attaching electrical wires to at least said second layer of cured conductive ink, wherein the wires are in electrical communication with at least said second layer of cured conductive ink. 21. The method of claim 20, wherein said advancing said substrate to a first printing location and said advancing said substrate to a second printing location each further include advancing said substrate at approximately fifty (50) feet per minute with respect to the first and second printing locations. 22. The method of claim 1, wherein said at least one conductive electrode includes a first conductive electrode and a second conductive electrode, said first and second conductive electrodes being in electrical communication with said substrate, and wherein said substrate is adapted to generate heat as electricity flows from said first electrode, through said substrate, and to said second electrode. 23. The method of claim 1, wherein said substrate heats to eighty-five (85) degrees centigrade when electrical current flows from said at least one electrode through said substrate.
