Abstract: Stereolithography is used to fabricate directly a single-piece, missile-usable, accurate, flightweight igniter without the use of intermediate, non-operational molds or prototypes in the fabrication process. The same prototype-less, direct stereolithography can be used to produce other missile-usable parts by designing each such part to be of a single-piece configuration and by using material that is suitable for both stereolithography and functional missile application.
