- Additive manufacturing also known as 3D printing and rapid prototyping is ‘the process of joining materials to make objects from 3D model data, generally layer upon layer. It is a suitable process to produce complex net shape parts, and prototypes. Additive Manufacturing empowers both design and industrial revolution, in various industrial sectors such as aerospace, energy, automotive, medical, tooling and consumer goods. In aerospace today, Additive Manufacturing is bringing lots of advantages and applications but manufacturing threaded fasteners or parts with threads is not much explored. In this study we are exploring this and trying to establish manufacturing threaded parts using additive manufacturing. This is going to give many benefits like reduced part cost, manufacturing and installation time and increased safety. The key features of such parts which makes AM as a best manufacturing method are – angled internal grove, provision for sealant for complete sealing, customized tread geometry, multiple threaded regions within the part etc. These types of parts has potential applications in different sections of Aircraft, flight testing, ground testing, spacecraft etc. Study of design and manufacture for Additive Manufacturing, Materials and Processes, theoretical evaluation of additive manufactured threaded parts and future scope are presented in this paper.
