Abstract

Additively manufactured parts are disclosed comprising an integral additively manufactured nut plate cradle, and methods of their manufacture and use in part and component installation and to facilitate joining parts and components to larger structures.

First claim

What is claimed is:

1. An additively manufactured part comprising:
an additively manufactured nut-retaining cradle integral with the additive manufactured part, said integral nut-retaining cradle comprising an integral cradle bed and at least one integral cradle wall, said integral cradle wall extending substantially perpendicularly from the integral cradle bed and said integral cradle wall extending from the integral cradle bed to a predetermined distance; and
wherein the integral cradle wall comprises at least one integral cradle wall nut-retaining feature, said integral cradle wall nut-retaining feature configured to receive a retainer, said retainer configured to engage the integral cradle wall nut-retaining feature, said integral cradle wall nut-retaining feature further configured to establish a restricted range of movement for a nut retained in the nut-retaining cradle along at least one axis.

2. The additively manufactured part according to claim 1 , wherein the integral cradle wall nut-retaining feature comprises at least one recess in at least one integral cradle wall.

3. The additively manufactured part according to claim 2 , wherein the recess extends through the integral cradle wall.

4. The additively manufactured part according to claim 2 , wherein the recess comprises a through-slot extending through the integral cradle wall.

5. The additively manufactured part according to claim 1 , wherein the retainer is selected from the group consisting of: a clip; a pin; a continuous ring; a discontinuous ring; and combinations thereof.

6. The additively manufactured part according to claim 1 , wherein the nut comprises a floating nut.

7. The additively manufactured part according to claim 1 , wherein the integral cradle bed comprises at least one integral cradle bed nut-orienting feature, said integral cradle bed nut-orienting feature configured to establish a restricted range of movement for a nut retained in the integral cradle bed along at least one axis.

8. The additively manufactured part of claim 7 , wherein the integral cradle bed nut-orienting feature comprises a post, said post extending a predetermined distance from the integral cradle bed.

9. The additively manufactured part according to claim 1 , wherein the integral cradle bed comprises:
a cradle bed upper surface, said cradle bed comprising a predetermined thickness, and
wherein the integral cradle bed upper surface extends a predetermined distance from a surface of the additively manufactured part.

10. The additively manufactured part according to claim 1 , wherein the integral cradle bed comprises:
a cradle bed upper surface; and
wherein the integral cradle bed upper surface is substantially flush with a surface of the additively manufactured part.

11. The additively manufactured part according to claim 1 , wherein the additively manufactured part comprises a non-metallic material, said non-metallic material selected from the group consisting of: a thermoset plastic material; a thermoplastic material; a composite material; a ceramic material; a carbon fiber-containing material;
a boron fiber-containing material; a glass fiber-containing material; an aramid fiber-containing material; polytetrafluoroethylene; polyethylene terephthalate; glycol modified polyethylene terephthalate; and combinations thereof.

12. The additively manufactured part according to claim 1 , wherein the additively manufactured part comprises a metallic material, said metallic material selected from the group consisting of: titanium; a titanium alloy; steel; aluminum; an aluminum alloy; cobalt; a cobalt alloy; bronze; copper; a copper alloy; and combinations thereof.

13. A structure comprising the additively manufactured part of claim 1 .

14. An additively manufactured part comprising:
an additively manufactured nut-retaining cradle integral with the additive manufactured part, said integral nut-retaining cradle comprising an integral cradle bed and at least one integral cradle wall, said integral cradle wall extending substantially perpendicularly from the integral cradle bed and said integral cradle wall extending from the integral cradle bed to a predetermined distance; and
wherein the integral cradle wall comprises at least one integral cradle wall nut-retaining feature, said integral cradle wall nut-retaining feature configured to receive a retainer, said retainer configured to engage the integral cradle wall nut-retaining feature, said integral cradle wall nut-retaining feature further configured to establish a restricted range of movement for a nut retained in the nut-retaining cradle along at least one axis;
wherein the vehicle is selected from the group consisting of: a manned terrestrial vehicle; an unmanned terrestrial vehicle; a manned aircraft; an unmanned aircraft; a manned rotorcraft; an unmanned rotorcraft; a manned spacecraft; an unmanned spacecraft; a manned surface water borne vehicle; an unmanned surface water borne vehicle; a manned sub-surface water borne vehicle; an unmanned sub-surface water borne vehicle; a satellite; a rocket; a missile; and combinations thereof.

15. A method of manufacturing a part, the method comprising:
using an additive manufacturing process to construct a part; and
forming a nut-retaining cradle for a nut plate assembly, said nut-retaining cradle additively manufactured integrally with the part and comprising a cradle bed and at least one integral cradle wall that includes at least one integral cradle wall nut-retaining feature configured to receive a retainer and further configured to establish a restricted range of movement for a nut retained in the cradle bed.

16. The method according to claim 15 , wherein the additive manufacturing process is selected from the group consisting of: direct energy deposition; direct metal laser sintering; direct metal printing; electron beam additive manufacturing; electron beam melting; electron beam powder bed; fused deposition modeling; indirect powder bed; laser cladding; laser deposition; laser deposition welding; laser deposition welding/integrated milling; laser engineering net shaping; laser freeform manufacturing; laser metal deposition with powder; laser metal deposition with wire; laser powder bed; laser puddle deposition; laser repair; powder directed energy deposition; stereolithography; selective laser melting; selective laser sintering; small puddle deposition, and combinations thereof.

17. The method according to claim 15 , wherein, in the step of using an additive manufacturing process to construct a part, the part selected from the group consisting of: comprises a non-metallic material, said non-metallic material comprising: a thermoset plastic material; a thermoplastic material; a composite material; a ceramic material; a carbon fiber-containing material, a boron fiber-containing material; a glass fiber-containing material; an aramid fiber-containing material; polytetrafluoroethylene; polyethylene terephthalate; glycol modified polyethylene terephthalate; or combinations thereof.

18. The method according to claim 15 , wherein, in the step of using an additive manufacturing process to construct a part, the part comprises a material selected from the group consisting of: a metallic material, said metallic material comprising: titanium; a titanium alloy; steel, aluminum; an aluminum alloy; cobalt; a cobalt alloy; bronze; copper; a copper alloy; and combinations thereof.
