Abstract
A system treats uneven surfaces of additive manufactured objects to improve the transparency and glossiness of the surfaces. 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 of the object and operates a sprayer to apply another fluid material to a surface of the object that is identified as being rougher based on the object's geometric data. A heater is provided to dry non-UV curable material applied to the object and a source of UV radiation is provided to cure UV curable material applied to the object.
