Abstract
An additive manufacturing apparatus includes a stage configured to hold a component. A radiant energy device is operable to generate and project radiant energy toward the stage. An actuator is configured to change a relative position of the stage relative to the radiant energy device. A feed module is configured to support a feed roll of a resin support upstream of the stage about a feed mandrel. A first control device is operably coupled with the feed mandrel. A take-up module is configured to support a take-up roll of the resin support downstream of the stage about a take-up mandrel. A second control device is operably coupled with the take-up mandrel. A computing system is operably coupled with one or more sensors. The computing system is configured to provide commands to at least one of the first control device or the second control device to respectively rotate the first control device or the second control device to obtain a target tension on the resin support.
