Abstract
A layer-by-layer three dimensional printing technique for printing on outer surfaces of a plurality of substrate elements passing through a printing route/zone while being rotated thereinside about a printing axis. At least one array of printing head units is used to define at least one printing route along the printing axis, where the at least one printing route is a substantially linear segment of a closed loop lane along which the objects are progressing. The print head units being configured for movement along radial axes, or one or more axes substantially perpendicular, to the printing axis, to allow layer-by-layer printing of said three-dimensional objects over said substrate elements while being rotated in said printing route.
