Abstract

The subject matter of this specification can be embodied in, among other things, a fuel delivery component, a substantially rigid, unitary structure formed as a single piece of material, and at least a first seamless lumen defined by the unitary structure as a first loop.

First claim

What is claimed is:

1. A method of manufacturing a fuel delivery component, the method comprising:
forming, by additive manufacturing, a substantially rigid, unitary structure as a single piece of material;
defining, within the unitary structure, at least a first seamless lumen as a first loop; and
forming at least one seamless fluid outlet seamlessly formed of the unitary structure, wherein the seamless fluid outlet defines a seamless outlet lumen in fluid communication with the first seamless lumen.

2. The method of claim 1 , wherein the unitary structure has a predetermined form.

3. The method of claim 1 , wherein the first seamless lumen is defined with a lengthwise varying cross-sectional area.

4. The method of claim 1 , further comprising defining, within the unitary structure, a second seamless lumen as a second loop, wherein the second seamless lumen is defined substantially parallel to the first seamless lumen.

5. The method of claim 1 , further comprising defining, within the unitary structure, a second seamless lumen as a second loop, wherein the second seamless lumen is defined substantially coaxial to the first seamless lumen.

6. The method of claim 1 , further comprising defining, within the unitary structure, a second seamless lumen as a second loop, wherein the first seamless lumen and the second seamless lumen are defined substantially helical relative to each other.

7. The method of claim 1 , further comprising defining a second seamless lumen defined by the unitary structure and disposed within the first seamless lumen.

8. The method of claim 7 , further comprising defining a plurality of support structures defined by the unitary structure along the lengths of the first seamless lumen and the second seamless lumen, and configured to position the first seamless lumen relative to the second seamless lumen.

9. The method of claim 8 , wherein the plurality of support structures are discontinuous along the lengths of the first seamless lumen and the second seamless lumen.

10. The method of claim 1 , further comprising:
defining, within the unitary structure, a second seamless lumen as a second loop; and,
defining, within the unitary structure, a third seamless lumen as a third loop;

wherein the first seamless lumen, the second seamless lumen, and the third seamless lumen are arranged as a non-intersecting weave.

11. The method of claim 1 , further comprising forming at least one seamless fluid connector seamlessly formed of the unitary structure, wherein the seamless fluid connector comprises a fluid fitting configured to couple the seamless fluid connector to an external fluid conduit and defines a seamless connecting lumen in fluid communication with the first seamless lumen.
