Abstract
An additive manufacturing apparatus can include a stage configured to hold one or more cured layers of resin that form a component. A radiant energy device can be operable to generate and project radiant energy in a patterned image. An actuator can be configured to change a relative position of the stage relative to the radiant energy device. A reclamation system can be downstream of the stage and can be configured to remove at least a portion of the resin from a resin support. The reclamation system can include a first collection structure configured to accept a resin support therethrough along a resin support movement direction. A first scraper is positioned within the first collection structure. The first scraper has an elongation axis that is offset from the resin support movement direction by an offset angle that is less than 90 degrees.
