1. A method comprising:
receiving a plurality of additively manufactured objects on a rotor, wherein the plurality of additively manufactured objects have excess material thereon;
removing the excess material from the plurality of additively manufactured objects by rotating the plurality of additively manufactured objects via the rotor; and
applying energy to the plurality of additively manufactured objects to cure a portion of each of the plurality of additively manufactured objects while the plurality of additively manufactured objects are on the rotor, wherein the energy selectively cures the portion of each of the plurality of additively manufactured objects while leaving a remaining portion of each of the plurality of additively manufactured objects in a partially cured or uncured state.
