Abstract
A reclamation system for an additive manufacturing apparatus can include a collection structure configured to remove at least a portion of the resin from a foil. A containment vessel can be configured to retain the resin removed from the foil. A drain can direct the resin from the containment vessel to a reservoir.
Claims13
A reclamation system for an additive manufacturing apparatus, the reclamation system comprising:
- a collection structure configured to remove at least a portion of a resin from a foil;
- a containment vessel configured to retain the resin removed from the foil;
- a drain directing the resin from the containment vessel to a reservoir;
- and
- a backing plate positioned on an opposing side of the foil from the collection structure, wherein the backing plate selectively provides pressure against the opposing side of the foil from the collection structure.

An additive manufacturing apparatus comprising:
- a stage configured to hold one or more cured layers of resin that form a component;
- a radiant energy device operable to generate and project radiant energy in a patterned image;
- an actuator configured to change a relative position of the stage relative to the radiant energy device;
- a reclamation system downstream of the stage and configured to remove at least a portion of the resin from a foil, wherein the reclamation system including a scraper;
- a first roller directing the foil partially therearound upstream of the scraper;
- and
- a second roller directing the foil partially therearound downstream of the scraper, wherein the scraper is configured to redirect the foil from a first translational direction to a second translational direction between the first roller and the second roller.
