Abstract
A method of separating excess resin from at least one object includes: (a) stereolithographically producing at least one object, each object having at least one retention feature () formed thereon, each object carrying excess resin on a surface thereof; then (b) mounting each object on at least one transfer frame (), each transfer frame having at least one retention member () that mates with the retention feature; (c) connecting each transfer frame to a rotor with the at least one object carried thereon; (d) centrifugally separating excess resin from each object by spinning the rotor with each transfer frame connected thereto while the at least one object remains connected to each transfer frame by the retention feature; then (e) removing each transfer frame from the rotor, with excess resin separated from each at least one object thereon.
