A component formed by an additive manufacturing process includes a body and a first vibration damper. The body is formed from an additive manufacturing material, and defines at least a first cavity completely enclosed within the body. The first vibration damper is disposed within the first cavity. The first vibration damper includes a flowable medium and a first solidified element formed from the additive manufacturing material. The flowable medium surrounds the first solidified element.

1. A method of forming a component, the method comprising: forming a body of the component from an additive manufacturing material;forming a first cavity within the body; andforming a first vibration damper within the first cavity by: forming a first solidified element by selectively solidifying the additive manufacturing material; andenclosing the first solidified element and a flowable medium within the first cavity. 2. The method in accordance with claim 1, wherein forming the first vibration damper further comprises forming a connecting element between a cavity wall of the first cavity and the first solidified element. 3. The method in accordance with claim 1, wherein enclosing the first solidified element and a flowable medium within the first cavity comprises enclosing unsolidified additive manufacturing material within the first cavity. 4. The method in accordance with claim 1, wherein forming a first solidified element comprises forming a first solidified element shaped substantially complementary to the first cavity. 5. The method in accordance with claim 1, wherein forming a first vibration damper within the first cavity further comprises: forming a second solidified element by selectively solidifying the additive manufacturing material; andenclosing the second solidified element within the first cavity. 6. The method in accordance with claim 1, further comprising forming a second cavity within the first solidified element and forming a second vibration damper within the second cavity. 7. The method in accordance with claim 1, wherein forming the body from the additive manufacturing material comprises forming the body by a selective laser sintering process, a direct metal laser sintering process, an electron beam melting process, a selective heat sintering process, a stereolithography process, or combinations thereof. 8. The method in accordance with claim 1, wherein the additive manufacturing material comprises one of a metal powder, a thermoplastic powder, a photopolymer resin, a thermoset resin, a thermoplastic resin, or combinations thereof. 9. The method in accordance with claim 1, wherein the first solidified element and the flowable medium occupy at least 95% of the first cavity. 10. The method in accordance with claim 9, wherein the first solidified element occupies 20%-90% of the first cavity and the flowable medium occupies 5%-100% of the first cavity. 11. The method in accordance with claim 10, wherein the first solidified element occupies 50%-80% of the first cavity and the flowable medium occupies 20%-50% of the first cavity. 12. The method in accordance with claim 1, wherein the first solidified element occupies 80% of the first cavity and the flowable medium occupies 10%-20% of the first cavity. 13. The method in accordance with claim 1, wherein the flowable medium comprises unsolidified additive manufacturing material. 14. The method in accordance with claim 1, wherein selectively solidifying the additive manufacturing material comprises solidifying by a selective laser sintering process, a direct metal laser sintering process, an electron beam melting process, a selective heat sintering process, a stereolithography process, or combinations thereof. 15. A method of forming a component, the method comprising: forming a body of the component from an additive manufacturing material;forming a first cavity within the body; andforming a first vibration damper within the first cavity by: forming a first solidified element by selectively solidifying the additive manufacturing material; andenclosing the first solidified elements and a flowable medium within the first cavity, wherein forming the first vibration damper further comprises forming a connecting element between a cavity wall of the first cavity and the first solidified element and detaching the first solidified element from the connecting element after the first solidified element is at least partially formed. 16. The method in accordance with claim 15, wherein detaching the first solidified element comprises detaching the first solidified element from the connecting element after the first cavity is formed. 17. A method of forming a component, the method comprising: forming a body of the component from an additive manufacturing material, wherein the additive manufacturing material comprises a metal powder;forming a first cavity within the body; andforming a first vibration damper within the first cavity by: forming a first solidified element by selectively solidifying the additive manufacturing material; andenclosing the first solidified element and a flowable medium within the first cavity, wherein the metal powder comprises alloys of cobalt, iron, aluminum, titanium, and/or nickel. 18. The method in accordance with claim 17, wherein the metal powder comprises cobalt chrome. 19. The method in accordance with claim 18, wherein the metal powder comprises steel. 20. A method of forming a component, the method comprising: forming a body of the component from a first additive manufacturing material;forming a first cavity within the body; andforming a first vibration damper within the first cavity by: forming a first solidified element by selectively solidifying a second additive manufacturing material different from the first additive manufacturing material; andenclosing the first solidified element and a flowable medium within the first cavity.
