1. An additive manufacturing apparatus, comprising:
at least two resin handling assemblies, each resin handling assembly including a resin support, wherein each resin support defines a build surface which is located in a build zone of the respective resin handling assembly;
a stage positioned adjacent the build zone and configured to hold a stacked arrangement of one or more cured layers of a radiant-energy-curable resin;
one or more actuators operable to manipulate a relative position of a selected one of the build surfaces and the stage,
a shifting mechanism operable to change the relative positions of the stage and the resin handling assemblies; and
a radiant energy apparatus positioned adjacent to the build zone opposite to the stage, and operable to generate and project radiant energy in a predetermined pattern;
wherein the one or more actuators are further configured to move the stage in a first direction and in a second direction transverse to the first direction between the selected one of the build surfaces and another build surface defined by another resin support.
