Am cylinder manufacturing method using sacrificial build tube

A non-transitory computer readable medium comprising a plurality of instructions which, when executed by a controller, cause the controller to:

• rotate a sacrificial component around a longitudinal axis to enable a print-head to deposit aerospace grade material on a surface of the sacrificial component;
• deposit, by the print-head, the aerospace grade material on the surface of the sacrificial component;
• deposit, by the print-head, a protective coating on the surface of the aerospace grade material;
• and
• in response to a completion of the deposit of the aerospace grade material on the surface of the sacrificial component and the deposit of the protective coating on the surface of the aerospace grade material, apply, by another controller using a device, a machine process in the longitudinal axis of a manufactured component to incompletely remove the sacrificial component and expose most but not all of the interior surface of the manufactured component that comprises the aerospace grade material.
