1. An additive manufacturing apparatus, comprising:
a build surface at least a portion of which is transparent configured to move in a downstream direction;
a first material depositor operable to deposit a curable resin to form a deposited resin layer on the build surface, the deposited resin layer being transported in the downstream direction by the build surface;
a stage positioned facing the build surface and configured to hold a stacked arrangement of one or more cured layers of the resin;
one or more actuators operable to change the relative positions of the build surface and the stage;
a radiant energy apparatus positioned adjacent to the build plate opposite to the stage, and operable to generate and project radiant energy on the resin through the build plate in a predetermined pattern;
a first sensing device configured to measure the thickness of the deposited resin layer, wherein the at least one first sensing device is configured to generate a signal indicative of the thickness of the deposited resin layer;
a first thickness adjusting mechanism configured to adjust the thickness of the deposited resin layer in response to the signal; and
an adjustment device configured to adjust the first thickness adjusting mechanism.
