X-Radiographic Parallax Reduction with 3D-Printed Fixturing

摘要

With the increasing viability and availability of 3D printers, the potential for precise and reliable fixture design is now possible. In this paper we explore the construction and performance of a 3D printed fixture used for Radiographic Non-Destructive Testing of aircraft countermeasure flares. The fixture is designed to minimize parallax, to be minimally intrusive to the resulting radiographic image, and to incorporate an intrinsic measure of safety in handling and positioning the item for inspection in order to ensure the highest quality product gets to the warfighter.
