Abstract
A method operates a three-dimensional object printer for production of cylindrical-shaped objects. The method uses a controller to operate an actuator operatively connected to a cylindrical member to rotate the cylindrical member within at least two supports, operate a plurality of ejectors in each of at least two printheads supplied with different materials to form portions of layers on the rotating cylindrical member with the different materials supplied to the at least two printheads, operate a linear actuator operatively connected to the cylindrical member to translate the cylindrical member bidirectionally in a direction parallel to a longitudinal axis of the rotating cylindrical member between the two supports, and operate a curing device to modify the layers formed on the rotating cylindrical member while the cylindrical member is rotating within the at least two supports and translated in the direction parallel to the longitudinal axis of the rotating cylindrical member.
