Abstract
A three-dimensional object printer enables production of cylindrically shaped objects. The printer includes a controller operatively connected to at least two printheads, at least one object treating device, and actuator that is operatively connected to a cylindrical member being supported by at least two supports. The controller is configured to operate the actuator to rotate the cylindrical member within the at least two supports, to operate the plurality of ejectors in each of the at least two printheads to form portions of layers on the rotating cylindrical member with the different materials supplied to the at least two printheads, and to operate the at least one object treating device to modify the layers formed on the rotating cylindrical member while the cylindrical member is rotating within the at least two supports.
