Each of the plurality of layers comprises at least one of a first curable material and a second curable material. The system also includes a leveling component configured to remove excess material from each of the plurality of layers after each layer is printed. The system includes a first recirculation loop configured to return the excess material that includes only the first curable material back to the printing component, and a second recirculation loop configured to return the excess material that includes only the second curable material back to the printing component. In addition, the system includes a waste bin configured to receive the excess material that includes both the first curable material and the second curable material.
