A printer system is provided for developing a three dimensional (3D) printed structure. The system includes a plurality of spaced apart sets of printing devices. A conveyor system is arranged to serially convey a print medium operatively with respect to each set so that printed voxels from each successive set can form successive layers of the 3D printed structure upon the print medium. A placement mechanism is configured to place an object upon layers of the 3D printed structure. The placement mechanism includes a translation mechanism configured to translate the object at substantially the same velocity as the conveyance of the print medium during placement of the object. A plurality of curing mechanisms is interleaved between the sets of printing devices and is configured to cure the printed voxels.
