Reclamation system for additive manufacturing
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.
1. 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.
2. The reclamation system of claim 1 , further comprising:
a scraper operably coupled with the collection structure and configured to remove the resin from the foil.
3. The reclamation system of claim 2 , wherein the scraper is configured to vibrate while removing the resin from the foil.
4. The reclamation system of claim 1 , further comprising:
an anchor plate operably coupled with the backing plate through a guide, the guide configured to support movement of the backing plate relative to the anchor plate.
5. The reclamation system of claim 4 , further comprising:
a pneumatic actuator operably coupled with the backing plate and configured to alter a position of the backing plate relative to the anchor plate.
6. The reclamation system of claim 4 , further comprising:
a brace fixedly supporting each of the anchor plate and the collection structure.
7. The reclamation system of claim 1 , wherein the backing plate is operably coupled with a transducer, the transducer configured to convert electrical energy to mechanical pressure waves through an ultrasonic movement generator.
8. The reclamation system of claim 1 , wherein a scraper is configured to contact the foil at an offset angle that is greater than 0 degrees and less than 180 degrees.
9. The reclamation system of claim 1 , further comprising:
a scraper operably coupled with the collection structure, the scraper having a vibrating head operably coupled with a transducer, the transducer configured to convert electrical energy to mechanical pressure waves through an ultrasonic movement generator.
10. 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.
11. The additive manufacturing apparatus of claim 10 , wherein the collection structure includes a scraper that is configured to contact the foil and direct the resin to a containment vessel.
12. The additive manufacturing apparatus of claim 10 , further comprising:
a containment vessel within the collection structure.
13. The additive manufacturing apparatus of claim 12 , further comprising:
a drain defined by the containment vessel and configured to direct the resin from the containment vessel to a reservoir.
