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. ## Claims ### Claim 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. ### Claim 2 (depends on 1) A build plate as recited in claim 1, wherein the insert is separate from and attachable with the surface. ### Claim 3 (depends on 1) A build plate as recited in claim 1, wherein the insert is removable from the surface. ### Claim 4 (depends on 1) A build plate as recited in claim 1, wherein the cavity includes a pocket extending a depth within the body. ### Claim 5 (depends on 1) A build plate as recited in claim 1, wherein the cavity includes a plurality of spaced apart pockets. ### Claim 6 (depends on 1) A build plate as recited in claim 1, wherein the cavity includes a plurality of pockets oriented in rows along the surface. ### Claim 7 (depends on 1) A build plate as recited in claim 1, wherein the surface includes a plurality of connected sections. ### Claim 8 (depends on 1) 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. ### Claim 9 (depends on 1) 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. ### Claim 10 (depends on 9) A build plate as recited in claim 9, wherein the surface is movable in a plurality of directions relative to the enclosure. ### Claim 11 (depends on 9) 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. ### Claim 12 (depends on 1) 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. ### Claim 13 (depends on 1) A build plate as recited in claim 1, wherein the insert includes a distal face having a planar configuration. ### Claim 14 (depends on 1) A build plate as recited in claim 1, wherein the insert includes a distal face having an angled configuration. ### Claim 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. ### Claim 16 (depends on 15) A build plate as recited in claim 15, wherein the insert is separate from and attachable with the surface. ### Claim 17 (depends on 15) A build plate as recited in claim 15, wherein the insert is removable from the surface. ### Claim 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. ### Claim 19 (depends on 18) A build plate as recited in claim 18, wherein the insert is separate from and attachable with the surface. ### Claim 20 (depends on 18) A build plate as recited in claim 18, wherein the insert is removable from the surface. ### Claim 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.
