Abstract

A method for manufacturing a tower structure, the method including printing and depositing, with at least one variable-width deposition nozzle of a printhead assembly, one or more layers of at least one wall element of the tower structure, the at least one wall element having an outer circumferential surface and an inner circumferential surface. The method also including forming, with the at least one variable-width deposition nozzle, at least one void into the at least one wall element. The method also including placing at least one reinforcement member within the at least one void so as to position the at least one reinforcement member closer to a neutral axis of the at least one wall element than at least one of the outer circumferential surface or the inner circumferential surface.

First claim

What is claimed is:

1. A method for manufacturing a tower structure, the method comprising:
printing and depositing, with at least one variable-width deposition nozzle of a printhead assembly, one or more layers of at least one wall element of the tower structure, the at least one wall element having an outer circumferential surface and an inner circumferential surface;
forming, with the at least one variable-width deposition nozzle, a plurality of voids into the at least one wall element, at least some of the plurality of voids arranged on the outer circumferential surface and the rest of the plurality of voids arranged on the inner circumferential surface; and
placing at least one reinforcement member within at least one of the plurality of voids so as to position the at least one reinforcement member at a neutral axis of the tower structure.

2. The method of claim 1 , wherein the variable-width deposition nozzle comprises a first side and a second side, the first side being fixed, the second side being movable with respect to the first side.

3. The method of claim 2 , further comprising:
establishing a fixed deposition path for the variable-width deposition nozzle by aligning and affixing the first side with respect to an inner reference curve or an outer reference curve of the at least one wall element; and
establishing a variable deposition path for the variable-width deposition nozzle by allowing the second side to move with respect to the first side during printing and depositing to form the at least one void.

4. The method of claim 3 , wherein forming, with the at least one variable-width deposition nozzle of the printhead assembly, the at least one void into the at least one wall element further comprises:
forming, with the at least one variable-width deposition nozzle, at least one void into at least one of the outer circumferential surface, the inner circumferential surface, or therebetween, of the at least one wall element by establishing the variable deposition path.

5. The method of claim 3 , wherein the variable-width deposition nozzle further comprises a flow regulator operably coupled between the first side and the second side, wherein forming the at least one void into the at least one wall element further comprises:
printing and depositing, via the variable-width deposition nozzle, the at least one wall element along the fixed and variable deposition paths, wherein the variable deposition path defines the at least one void; and
regulating, via the flow regulator, the printing and depositing to form the at least one void.

6. The method of claim 1 , wherein forming, with the at least one variable-width deposition nozzle of the printhead assembly, the at least one void into the at least one wall element further comprises:
forming, with the at least one variable-width deposition nozzle of the printhead assembly, at least one void between two or more wall elements of the tower structure.

7. The method of claim 6 , wherein printing and depositing, with at least one variable-width deposition nozzle of the printhead assembly, the one or more layers of the at least one wall element of the tower structure further comprises:
printing and depositing, with a first variable-width deposition nozzle of the printhead assembly, the one or more layers of a first wall element of the at least one wall element of the tower structure; and
concurrently printing and depositing, with a second variable-width deposition nozzle of the printhead assembly, the one or more layers of a second wall element of the at least one wall element of the tower structure adjacent to the first wall element.

8. The method of claim 7 , wherein the first wall element is an outer wall element and the second wall element is an inner wall element, and wherein forming, with the at least one variable-width deposition nozzle, the at least one void into the at least one wall element further comprises:
forming, with the first variable-width deposition nozzle, one or more of a first plurality of recesses into the first wall element; and
forming, with the second variable-width deposition nozzle, one or more of a second plurality of recesses into the second wall element.

9. The method of claim 1 , wherein the at least one void defines at least one of an arcuate shape or a non-arcuate shape.

10. The method of claim 1 , wherein the at least one reinforcement member is one or more of a plurality of reinforcement members and the at least one void is one or more of a plurality of voids, and wherein the placing at least one reinforcement member within the at least one void further comprises:
placing at least one of the plurality of reinforcement members within each of the plurality of voids.

11. A tower structure, comprising:
a base tower section comprising at least one printed wall element including one or more layers, the at least one printed wall element having an outer circumferential surface and an inner circumferential surface;
a transition assembly arranged adjacent to the base tower section;
a plurality of voids formed into the at least one printed wall element during printing and depositing of the at least one printed wall element, at least some of the plurality of voids arranged on the outer circumferential surface and the rest of the plurality of voids arranged on the inner circumferential surface; and
at least one reinforcement member positioned within at least one of the plurality of voids, the at least one reinforcement member extending through at least a portion of the base tower section and at least partially through the transition assembly;
wherein the at least one reinforcement member in the at least one void positions the at least one reinforcement member at a neutral axis of the tower structure.

12. The tower structure of claim 11 , wherein the at least one void formed into the at least one printed wall element is at least one void formed into at least one of the outer circumferential surface or the inner circumferential surface, or therebetween, of the at least one printed wall element.

13. The tower structure of claim 11 , wherein the at least one void formed into the at least one printed wall element is at least one void formed between two or more printed wall elements of the base tower section.

14. The tower structure of claim 11 , wherein the at least one void defines at least one of an arcuate shape or a non-arcuate shape.
