This paper describes the design of a 3D printer by reducing its cost to the optimum level. 3D printing technology has become an emerging topic in today’s technological discussion. All over the world companies and individuals are doing experiments by extruding plastics, metal objects for prototyping or their own needs. To satisfy these demands we have developed a machine named as “Additive Manufacturing Machine” based on 3D printing technology. Using this machine user can turn any digital file into a three-dimensional (3D objects) physical products. In this paper, we will look for the additive manufacturing. First, we will define what we mean by this term. Then the methods used in this technology and how we have reduced its cost. Then we will delve a bit into the advantages over conventional methods of manufacturing. We shall observe a lot of applications in today’s world. Finally, the future potential of this technology is outlined.
