Abstract

A fluid conduit includes, a body, a first conduit portion connected to the body, a second conduit portion connected to the body, and a base connected to the second conduit portion. The body, the first conduit portion, the second conduit portion, and the base may be formed as a monolithic component via additive manufacturing. A method of making a fluid conduit may include forming sets of layers. The set of layers may include parts or portions of the fluid conduit and/or supports.

First claim

What is claimed is:

1. A fluid conduit, comprising:
a body;
a first conduit portion connected to the body;
a second conduit portion connected to the body; and
a base connected to the second conduit portion;
wherein the body, the first conduit portion, the second conduit portion, and the base are formed as a monolithic component via additive manufacturing; the first conduit portion is connected to a first fluid port of the body; the second conduit portion is connected to a second fluid port of the body; the body includes a third fluid port configured for connection with a fluid pump; and the body includes a nozzle connected to and/or extending from the third fluid port towards the first fluid port; and wherein the base includes a mesh configured to receive fluid, the mesh including an internal chamber defined by a plurality of walls each having a plurality of apertures.

2. The fluid conduit of claim 1 , wherein at least one of:
the first conduit portion, the first fluid port, the third fluid port, and the nozzle are aligned with a longitudinal axis of the body;
a longitudinal axis of the second conduit portion extends through the nozzle; and
the longitudinal axis of the body is substantially perpendicular to the longitudinal axis of the second conduit portion.

3. The fluid conduit of claim 1 , wherein a cross-section of the second conduit portion includes a tear drop configuration.

4. The fluid conduit of claim 3 , wherein the tear drop configuration includes a rounded portion and an angled or pointed portion.

5. The fluid conduit of claim 1 , wherein the mesh includes a rectangular configuration.

6. The fluid conduit of claim 1 , wherein the fluid conduit does not include sealing members between any of the base, the mesh, the first conduit portion, the body, or the second conduit portion.

7. The fluid conduit of claim 1 , including an internal fluid passage extending from the base, through the second conduit portion, through the body, and through the first conduit portion.

8. The fluid conduit of claim 7 , wherein the nozzle extends at least partially into the internal fluid passage.

9. The fluid conduit of claim 1 , wherein the nozzle includes a tapered portion that tapers radially inward and toward the first fluid port.

10. A method of making a fluid conduit, the fluid conduit including a body, a first conduit portion, a second conduit portion, and a base, the body, the first conduit portion, the second conduit portion, and the base being formed as a monolithic component via additive manufacturing; the first conduit portion connected to a first fluid port of the body, the second conduit portion connected to a second fluid port of the body, the body including a third fluid port configured for connection with a fluid pump, and the body including a nozzle connected to and/or extending from the third fluid port towards the first fluid port, the method comprising:
forming a first set of layers, the first set of layers including parts of a first support, a second support, and a third support;
forming a second set of layers, the second set of layers including portions of the body and the second support;
forming a third set of layers, the third set of layers including portions of the body and the second conduit portion; and
forming a fourth set of layers, the fourth set of layers including portions of the first conduit portion;
wherein forming the second set of layers includes forming portions of a mesh of the base, the mesh including an internal chamber defined by a plurality of walls each having a plurality of apertures.

11. The method of claim 10 , including removing the first support, the second support, and the third support.

12. The method of claim 11 , including removing powder from the base.

13. The method of claim 12 , wherein removing powder from the base includes providing a fluid to one of a channel and a nozzle of the base, and the powder moving through the other of the channel and the nozzle.

14. The method of claim 10 , wherein at least one of the second set of layers and the third set of layers includes parts of the nozzle disposed within the body.

15. The method of claim 10 , wherein forming the first set of layers includes forming at least portions of a cavity and a channel connected to the cavity.

16. The method of claim 10 , wherein forming the first set of layers includes forming, in the first support, at least portions of a cavity, a first channel connected to the cavity, and a second channel connected to the cavity; and removing powder from the base includes providing a fluid to one of the first channel and the second channel, and the powder moving through the other of the first channel and the second channel.

17. The method of claim 10 , wherein the mesh includes a rectangular configuration and a plurality of rectangular apertures; and the base includes a circular section from which the mesh extends.

18. The method of claim 10 , wherein the third support includes a plurality of columns of different lengths and the plurality of columns are configured for removal from the base.

19. The method of claim 10 , wherein the first support includes a plurality of columns extending from a first end of the body to a flange of the body, and the flange is disposed at a second end of the body.

20. The method of claim 19 , wherein at least one of the plurality of columns includes at least three parallel column sections disposed at a distance from each other.
