Abstract

A component is provided that includes at least one passageway. In another aspect, a component, such as a lamp or a vehicular washer jet, is made of layers of material, a light curable material and/or multiple built-up materials. Another aspect uses a three-dimensional printing machine to emit material from an ink jet printing head to build up a component.
