Resin reclamation centrifuge rotor for additively manufactured objects

A catch pan for receiving residual resin separated from additively manufactured objects, said catch pan mounted on a rotor in a centrifugal separator, said catch pan comprising:

• a back wall, a pair of oppositely facing side walls connected to or extending from said back wall, and a bottom wall connected to or extending from said back wall and said side walls, said back wall having an inner surface and an outer surface;
• with:
• (i) said back wall sloping radially outward with respect to an axis of rotation of said rotor as it approaches said bottom wall, and said bottom wall sloping downward as it approaches said back wall, to together define an acute angle and form a resin pool where centrifugally separated resin can accumulate, (ii) said back wall inner surface faces said axis of rotation and is concave with respect to said axis of rotation, or (iii) a combination of (i) and (ii).
