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.

A method for manufacturing a built-up object, in which the built-up object includes a plurality of blades provided around a shaft body at circumferential intervals, and concave portions provided between adjacent ones of the blades, each of the concave portions having a curved shape in a section perpendicular to an axial direction, the method includes: a building step of depositing weld beads obtained by melting and solidifying a filler material on a circumferential surface of a base material having a circular shape in a sectional view and having a larger diameter than a bottom portion circle passing through bottom portions of the concave portions, thereby forming built-up portions to serve as the blades; and a cutting step of cutting parts of surfaces of the built-up portions and the circumferential surface of the base material, thereby forming the blades and the concave portions between the blades.

Heat exchangers are manufactured by three-dimensional (3D) printers by printing subsequent layers of a material in a print direction. The heat exchangers include one or more tubes. The one or more tubes are configured to transport a fluid to be heated or cooled. Each of the one or more tubes defines a slope that is within a threshold angle of the print direction. The heat exchangers include a plurality of fins that are each configured to intersect with the one or more tubes while allowing fluid flow between the plurality of fins to heat or cool the fluid. Each fin of the plurality of fins defines a slope that is within a threshold angle of the print direction.
