Abstract

A build plate system includes a body defining at least one cavity. An insert is sized and shaped to fit within the at least one cavity such that the at least one cavity orients the insert for forming at least a portion of a screw shaft thereon by a manufacturing method using an additive manufacturing apparatus. In some embodiments, systems, spinal constructs, surgical instruments and methods are disclosed.

First claim

What is claimed is:

1. A build plate system comprising:
a body comprising a surface defining at least one cavity, and
an insert sized and shaped to fit within the at least one cavity such that the at least one cavity orients the insert for forming at least a portion of a screw shaft thereon by a manufacturing method using an additive manufacturing apparatus,
wherein the at least one cavity is selectively oriented to control distal portion thread formation, material deposition timing and/or material heating.

2. A build plate as recited in claim 1 , wherein the insert is separate from and attachable with the surface.

3. A build plate as recited in claim 1 , wherein the insert is removable from the surface.

4. A build plate as recited in claim 1 , wherein the cavity includes a pocket extending a depth within the body.

5. A build plate as recited in claim 1 , wherein the cavity includes a plurality of spaced apart pockets.

6. A build plate as recited in claim 1 , wherein the cavity includes a plurality of pockets oriented in rows along the surface.

7. A build plate as recited in claim 1 , wherein the surface includes a plurality of connected sections.

8. A build plate as recited in claim 1 , wherein the surface includes a planar surface configured as a powder bed of the additive manufacturing apparatus.

9. A build plate as recited in claim 1 , wherein the additive manufacturing apparatus includes an enclosure defining a working chamber configured to receive the body.

10. A build plate as recited in claim 9 , wherein the surface is movable in a plurality of directions relative to the enclosure.

11. A build plate as recited in claim 9 , wherein the additive manufacturing apparatus includes a processor that, in operation of the apparatus, controls movement of the surface relative to the enclosure.

12. A build plate as recited in claim 1 , wherein the insert includes a distal face disposed, in performance of the manufacturing method, in a flush orientation with a planar surface of the surface.

13. A build plate as recited in claim 1 , wherein the insert includes a distal face having a planar configuration.

14. A build plate as recited in claim 1 , wherein the insert includes a distal face having an angled configuration.

15. A build plate system comprising:
a body comprising a surface defining at least one cavity, and
an insert sized and shaped to fit within the at least one cavity such that the at least one cavity orients the insert for forming at least a portion of a screw shaft thereon by a manufacturing method using an additive manufacturing apparatus,
wherein the cavity includes a plurality of pockets oriented in rows along the surface.

16. A build plate as recited in claim 15 , wherein the insert is separate from and attachable with the surface.

17. A build plate as recited in claim 15 , wherein the insert is removable from the surface.

18. A build plate system comprising:
a body comprising a surface defining at least one cavity, and
an insert sized and shaped to fit within the at least one cavity such that the at least one cavity orients the insert for forming at least a portion of a screw shaft thereon by a manufacturing method using an additive manufacturing apparatus,
the surface includes a plurality of connected sections.

19. A build plate as recited in claim 18 , wherein the insert is separate from and attachable with the surface.

20. A build plate as recited in claim 18 , wherein the insert is removable from the surface.

21. A build plate system comprising:
a body defining at least one cavity, and
an insert sized and shaped to fit within the at least one cavity such that the at least one cavity orients the insert for forming at least a portion of a screw shaft thereon by a manufacturing method using an additive manufacturing apparatus,
wherein the insert includes a distal face having an angled configuration.
