Claim 10:
11. An additive manufacturing apparatus comprising:
a feed module configured to operably couple with a first end portion of a foil;
a take-up module configured to operably couple with a second end portion of a foil;
a stage configured to hold one or more cured layers of a resin that form a component;
a radiant energy device positioned opposite to the stage, the radiant energy device operable to generate and project radiant energy in a predetermined pattern;
an actuator configured to change a relative position of the stage and the foil;
a reclamation system configured to remove at least a portion of the resin from the foil;
an accumulator positioned between the stage and the reclamation system, wherein the accumulator defines a cavity configured to retain at least a section of an intermediate portion of the foil; and
a computing system configured to determine a speed of the second end portion of the foil downstream of the accumulator based on an amount of the foil within the cavity.
