Abstract

A method is provided involving an additive manufacturing system. This method includes a step of forming a first fluid conduit using the additive manufacturing system. The method also includes a step of providing a fluid coupling. The fluid coupling includes the first fluid conduit and a second fluid conduit. The first fluid conduit is connected to and fluidly coupled with the second fluid conduit. The first fluid conduit has a first configuration. The second fluid conduit has a second configuration that is different than the first configuration.

First claim

What is claimed is:

1. A method involving an additive manufacturing system, the method comprising:
forming a first fluid conduit using the additive manufacturing system;
forming a second fluid conduit as a discrete and physically separate unit from the first fluid conduit; and
providing a fluid coupling, the fluid coupling including the first fluid conduit and the second fluid conduit, and the providing of the fluid coupling comprising attaching and fluidly coupling the first fluid conduit and the second fluid conduit together after the forming of the second fluid conduit;
wherein the first fluid conduit has a first configuration, the second fluid conduit has a second configuration that is different than the first configuration, and a joint between the first fluid conduit and the second fluid conduit has a non-rectangular configuration.

2. The method of claim 1 , further comprising forming the second fluid conduit using the additive manufacturing system.

3. The method of claim 1 , wherein the first fluid conduit interlocks with the second fluid conduit at a joint.

4. The method of claim 1 , wherein
the first fluid conduit has a cross-section with a first shape; and
the second fluid conduit has a cross-section with a second shape that is different than the first shape.

5. The method of claim 1 , wherein
the first fluid conduit forms a first flowpath with a first cross-sectional area; and
the second fluid conduit forms a second flowpath with a second cross-sectional area that is different than the first cross-sectional area.

6. The method of claim 1 , wherein the attaching of the first fluid conduit and the second fluid conduit together comprises attaching the first fluid conduit to the second fluid conduit with filler material.

7. The method of claim 6 , wherein the filler material comprises a metal seal.

8. The method of claim 6 , wherein the filler material comprises an elastomeric seal.

9. The method of claim 1 , wherein the attaching of the first fluid conduit and the second fluid conduit together comprises bonding the first fluid conduit to the second fluid conduit with bonding material.

10. The method of claim 1 , wherein the attaching of the first fluid conduit and the second fluid conduit together comprises welding the first fluid conduit to the second fluid conduit.

11. The method of claim 1 , wherein the attaching of the first fluid conduit and the second fluid conduit together comprises brazing the first fluid conduit to the second fluid conduit.

12. The method of claim 1 , wherein the attaching of the first fluid conduit and the second fluid conduit together comprises adhering the first fluid conduit to the second fluid conduit with an adhesive.

13. The method of claim 1 , wherein the joint comprises a beveled lap joint.

14. The method of claim 1 , wherein the joint comprises a brindle joint.

15. The method of claim 1 , wherein the joint comprises a tabled splice joint.

16. The method of claim 1 , wherein the forming of the first fluid conduit comprises additively manufacturing the first fluid conduit using the additive manufacturing system.

17. The method of claim 1 , wherein the first fluid conduit is fluidly coupled with the second fluid conduit in a serial arrangement.

18. A method involving an additive manufacturing system, the method comprising:
forming a first fluid conduit using the additive manufacturing system;
forming a second fluid conduit as a discrete and physically separate unit from the first fluid conduit; and
providing a fluid coupling, the fluid coupling including the first fluid conduit and the second fluid conduit, and the providing of the fluid coupling comprising attaching and fluidly coupling the first fluid conduit and the second fluid conduit together after the forming of the second fluid conduit;
wherein the first fluid conduit has a first configuration, the second fluid conduit has a second configuration that is different than the first configuration, and the first fluid conduit interlocks with the second fluid conduit.

19. The method of claim 18 , wherein
the first fluid conduit has a cross-section with a first shape; and
the second fluid conduit has a cross-section with a second shape that is different than the first shape.

20. The method of claim 18 , wherein
the first fluid conduit forms a first flowpath with a first cross-sectional area; and
the second fluid conduit forms a second flowpath with a second cross-sectional area that is different than the first cross-sectional area.

21. A method involving an additive manufacturing system, the method comprising:
providing a fluid coupling that includes a first fluid conduit and a second fluid conduit that is connected to and fluidly coupled in serial with the first fluid conduit at a joint;
the providing of the fluid coupling comprising additively manufacturing at least the first fluid conduit using an additive manufacturing system;
wherein the first fluid conduit is attached to the second fluid conduit at the joint by a bridge that is formed integral with the first fluid conduit and extends from the first fluid conduit to the second fluid conduit;
wherein the first fluid conduit is further attached to the second fluid conduit at the joint by filler material that contacts the first fluid conduit, the second fluid conduit and the bridge;
wherein the first fluid conduit has a first configuration;
wherein the second fluid conduit has a second configuration that is different than the first configuration.

22. The method of claim 21 , wherein the joint has a non-rectangular configuration.
