Abstract
A method of separating excess resin from at least one object, includes: (a) stereolithographically producing at least one object on at least one carrier platform, each carrier platform having a planar build surface to which at least one object is connected, each object carrying excess resin on a surface thereof; then (b) mounting each carrier platform to a rotor; (c) centrifugally separating excess resin from each object by spinning the rotor with each carrier platform connected thereto while each object remains connected to each carrier platform; and then (d) removing each carrier platform from the rotor with each object thereon, with excess resin separated therefrom.
