1. A method, comprising:
applying an additive manufacturing process to a build tube around a longitudinal axial direction of the build tube by rotating the build tube around a longitudinal axis;
translating, by the additive manufacturing process, a print-head in a parallel configuration to the longitudinal axis to enable the print-head to deposit an aerospace grade material on a surface of the build tube to form a manufactured component; and
after completion of the additive manufacturing process, applying, by a device, a machining process in the longitudinal axis of the manufactured component to incompletely remove the build tube, wherein the machining process comprises machining the build tube in an interior of the manufactured component to expose most but not all of the interior surface of the manufactured component.
