Abstract: A method of making a three-dimensional object from a polymerizable resin, the method comprising the steps of: (a) providing a carrier platform on which the three-dimensional object can be formed; (b) producing the three-dimensional object adhered to the carrier platform from the polymerizable resin by stereolithography, the object having residual resin on the surface thereof; (c) immersing the object in a wash liquid with the object remaining adhered to the carrier platform; (d) agitating (i) the object in said wash liquid (e.g., by spinning), (ii) the wash liquid with the object immersed therein (e.g., by sonication of the wash liquid), or (iii) both the object in the wash liquid and the wash liquid with the object immersed therein, to at least partially remove residual resin from the surface of the object; (e) separating the object from the wash liquid, with the object remaining adhered to the carrier platform, the object having residual wash liquid on the surface thereof; (f) agitating the object (e.g.

Abstract: A rotor for separating residual resin from additively manufactured objects in a centrifugal separator, the rotor including a rotor base and a plurality of engagement members configured to secure additively manufactured, light polymerized, objects to the rotor base, each object carrying unpolymerized resin on a surface thereof. The improvement includes a plurality of catch pans removably connected to the base, each catch pan configured to receive unpolymerized resin therein upon centrifugal separation of the resin from the additively manufactured, light polymerized, objects.
