Abstract
A method of manufacturing an impeller for a thermal management device includes partially curing a curable liquid in a curable liquid bath to form a first stage rotor, removing the first stage rotor from the curable liquid bath, the first stage rotor having excess curable liquid on a surface thereof, rotating the first stage rotor to displace the excess curable liquid radially outward from a rotational axis to compensate for imbalances in the first stage rotor, and fully curing the first stage rotor and at least a portion of the excess curable liquid to produce a second stage rotor that is more rotationally balanced than the first stage rotor.
