Abstract

A component includes a body, and an interface in the body defining a first and second portion of the body made by different melting beam sources of a multiple melting beam source additive manufacturing system during a single build. The component also includes a channel extending through the body. The channel includes an interface-distant area on opposing sides of the interface, each interface-distant area having a first width. The channel also includes an enlarged width area fluidly communicative with the interface-distant areas and spanning the interface, the enlarged width area having a second width larger than the first width. Any misalignment of the melting beams at the interface is addressed by the enlarged width area, eliminating the problem of reduced cooling fluid flow in the channel.

First claim

What is claimed is:

1. A component, comprising:
a body;
an interface in the body, the interface defining a first and second portion of the body made by different melting beam sources of a multiple melting beam source additive manufacturing system during a single build; and
a channel extending through the body,
wherein the channel includes an interface-distant area on opposing sides of the interface, each interface-distant area having a first width, and
wherein the channel includes an enlarged width area fluidly communicative with the interface-distant areas and spanning the interface, the enlarged width area having a second width larger than the first width,
wherein the second width includes a third width in the first portion of the body on a first side of the interface, and a fourth width in the second portion of the body on a second side of the interface, wherein the third width and the fourth width are each larger than the first width.

2. The component of claim 1 , wherein the third width in the first portion is misaligned with the fourth width in the second portion, creating a step at the interface.

3. The component of claim 1 , wherein the third width and the fourth width are identical.

4. The component of claim 1 , wherein the second width tapers from the interface to the first width.

5. The component of claim 1 , wherein the different melting beam sources have respective fields that meet along a line at the interface, the interface being planar.

6. The component of claim 1 , wherein the different melting beam sources have respective fields that overlap at the interface, the interface being a three-dimensional region, wherein the enlarged width area extends through the three-dimensional region of the interface.

7. The component of claim 1 , wherein the interface-distant area and the enlarged width area each have a circular cross-sectional shape, and the first and second width dimensions are diameters.

8. The component of claim 1 , wherein the interface-distant area has a first cross-sectional shape and the enlarged width area has a different, second cross-sectional shape.

9. The component of claim 8 , wherein the interface-distant area has a circular cross-sectional shape, and the enlarged width area has a substantially elliptical cross-sectional shape, a distance of each axis of the substantially elliptical cross-sectional shape being larger than the first width.

10. The component of claim 1 , wherein the interface includes a plurality of interfaces in the body and the enlarged width area includes a plurality of enlarged width areas along a length of the channel, each enlarged width area spanning a respective interface of the plurality of interfaces.

11. A component, comprising:
a body;
an interface in the body, the interface defining a first and second portion of the body made by different melting beam sources of a multiple melting beam source additive manufacturing system during a single build; and
a channel extending through the body,
wherein the channel includes an interface-distant area on opposing sides of the interface, each interface-distant area having a first width, and
wherein the channel includes an enlarged width area fluidly communicative with the interface-distant areas and spanning the interface, the enlarged width area having a second width larger than the first width, wherein the interface-distant area has a first cross-sectional shape and the enlarged width area has a different, second cross-sectional shape.

12. The component of claim 11 , wherein the second width includes a third width in the first portion of the body on a first side of the interface, and a fourth width in the second portion of the body on a second side of the interface, wherein the third width and the fourth width are each larger than the first width, and wherein the third width in the first portion is misaligned with the fourth width in the second portion, creating a step at the interface.

13. The component of claim 12 , wherein the third width and the fourth width are identical.

14. The component of claim 11 , wherein the second width tapers from the interface to the first width.

15. The component of claim 11 , wherein the different melting beam sources have respective fields that meet along a line at the interface, the interface being planar.

16. The component of claim 11 , wherein the different melting beam sources have respective fields that overlap at the interface, the interface being a three-dimensional region, wherein the enlarged width area extends through the three-dimensional region of the interface.

17. The component of claim 11 , wherein the interface-distant area and the enlarged width area each have a circular cross-sectional shape and the first and second width dimensions are diameters.

18. The component of claim 11 , wherein the interface-distant area has a circular cross-sectional shape, and the enlarged width area has a substantially elliptical cross-sectional shape, a distance of each axis of the substantially elliptical cross-sectional shape being larger than the first width.

19. The component of claim 11 , wherein the interface includes a plurality of interfaces in the body and the enlarged width area includes a plurality of enlarged width areas along a length of the channel, each enlarged width area spanning a respective interface of the plurality of interfaces.
