Abstract

An additive manufacturing apparatus (10) includes a feed module (22) and a take-up module (24) that are configured to operably couple with a foil (26). A stage (18) is configured to hold one or more cured layers of a resin (R) that form a component (12). A radiant energy device (20) is positioned opposite to the at least one stage (18). The radiant energy device (20) is operable to generate and project radiant energy in a predetermined pattern. An actuator (40) is configured to change a relative position of the at least one stage (18) and the foil (26). An accumulator (64) is positioned between the feed module (22) and the take-up module (24). The accumulator (64) is configured to retain an intermediate portion of the foil (26) to allow a first portion of the foil (26) upstream of the accumulator (64) to move at a first speed and a second portion of the foil (26) downstream of the accumulator (64) to move at a second speed during a defined time period.
