Abstract
A system treats uneven surfaces of additive manufactured objects to improve the transparency and glossiness of the surfaces. The system operates a sprayer to apply fluid material used to form the uneven surface to the uneven surface to smooth the surface or the system operates an actuator to dip the additive manufactured object into a bath of fluid material that is the same as the material used to form the uneven surface to smooth the surface. A heater is provided to dry non-UV curable material applied to the uneven surface and a source of UV radiation is provided to cure UV curable material applied to the uneven surface.
