Polymer gears find its applications in all the segments of mechanical power transmission system because of its high strength to weigh ratio. They are manufactured using machine cutting technique or by injection moulding which are costly due to mold cost and are more time consuming process. Additive manufacturing technique can be implemented because of its compatibility to produce complex designs and for customized requirements. The literature review shows that 3D printing technology is useful for Product development for fast product delivery. Additive manufacturing the gears will results into product development in short time and at low cost. These types of Gears can be used in any power transmission system and can be manufactured with required load carrying capacity and complex designs. Gear manufactured using additive manufacturing methods will reduce the manufacturing time, easy to make customized gears instantly, reduce noise generated during meshing of gear at high speed, low rate of wear and increase in life of gear. Keywords: Polymer Gear, Additive Manufacturing, 3D Printing. I. INTRODUCTION Additive Manufacturing (AM) is a term to describe set of technologies that create 3D objects by adding layer-upon-layer of material. Materials can vary from technology to technology. The term Additive Manufacturing holds within such technologies like Rapid Prototyping (RP), Direct Digital Manufacturing (DDM), Layered Manufacturing and 3D Printing. There are different 3d printing methods that were developed to build 3D structures and objects. Some of them are very popular nowadays; others have been dominated by competitors. FDM is the more preferred method of printing components in additive manufacturing industry because of its availability and low cost of manufacturing. 3D printing materials such as PLA, ABS, Nylon 12 and PC have been shortlisted among the other materials. Finally PLA is selected for manufacturing because its Properties are matching with actual Properties of the Transmission gear. In this project work, reverse engineering Method is used to design all the Parameters of the Transmission Gear and 3D Modelling of Gear has been done with CAD Modelling software Solidworks 2015. 3D Printing technique is imparted to produce a power transmission gear of Videocon washing machine. Prepare cost estimation for gear manufacturing and finally develop helical gear with 3D printer.
