Fluid couplings and methods for additive manufacturing thereof
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.
1. A method involving an additive manufacturing system, the method comprising:
forming a first fluid conduit and a second fluid conduit using the additive manufacturing system; and providing a fluid coupling, the fluid coupling including the first fluid conduit and the second fluid conduit, the first fluid conduit connected to and fluidly coupled with the second fluid conduit; and
connecting and fluidly coupling the first fluid conduit to the second fluid conduit through a compliant intermediate fluid conduit that is formed integral with the first and second fluid conduit;
wherein the first fluid conduit has a first configuration, and the second fluid conduit has a second configuration that is different than the first configuration.
2. The method of claim 1 , wherein the second fluid conduit is formed integral with the first fluid conduit.
3. The method of claim 2 , wherein the first fluid conduit is connected to and fluidly coupled with the second fluid conduit during the forming of the first and the second fluid conduits.
4. The method of claim 2 , further comprising fluidly coupling the first fluid conduit to the second fluid conduit after the forming of the first and the second fluid conduits.
5. 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.
6. 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.
7. The method of claim 1 , wherein the compliant intermediate fluid conduit is configured to flex thereby allowing towards and away movement, side-to-side movement and twisting movement between the first fluid conduit and the second fluid conduit.
8. The method of claim 1 , wherein the compliant intermediate fluid conduit is configured to enable towards and away movement between the first fluid conduit and the second fluid conduit.
9. The method of claim 1 , wherein the compliant intermediate fluid conduit is configured to enable side-to-side movement between the first fluid conduit and the second fluid conduit.
