In recent years, Computer Aided Manufacturing and Computer Aided Design (CAD/CAM ) have attracted attention of many artisans majorly due to direct role of computer in production trend and could not only reduce human errors considerably but also increase production and exploitation speed. Global trade and intensity of competition between manufacturers converted time of presenting a product to consumer market into determining factor of sale. Today, components are manufactured with the devices which are based on CNC machining and are programmable. But machining devices which are applied for production should have higher capabilities based on complexity of work piece which leads to increase of expense and time. Therefore, there is need for the process in which complexities of work piece are independent of the device complexities and when the piece becomes more complex, time and cost of production don’t grow considerably. This process can be regarded as additive manufacturing(AM) process. Use of this process not only increases production capabilities of the complex parts but also considerably reduces time and cost of production. Additive manufacturing is considered as production techniques in which parts are fabricated from a 3D CAD file layer-by layer. Depending on the used material and the applied bonding technology between the lines and layer many AM techniques have been developed. Processing metallic and ceramic material are of interest due to uniqes advantages that offered by these process. Among AM processes, 3D printing has gained many attentions for fabricating different types of material in reduced time and cost. It is likely that manufacturing of metallic components via 3D printing may role a crussial issue in the development of such processes in the next years. The main goal of this study was focoused on fabrication of three-dimentional of metal parts through 3D printing technology. In this research, firstly conceptual and mechanical design of a 3D printing system capable to fabricate multiple materials was carried out. In the next stage of the research and for feasibility study of manufacturing a 3D printing, thermal nozzle of a HP printer was used and a printer with powder manual feed was designed, manufactured and assembled. To estimate capability of the system, benchmark parts were manufactured by combining stainless steel powder 314 and PVA powder. Dimensional and optical measurements of the produced parts were done and dimensional accuracy was estimated. The obtained results confirm creation of metal parts with the provided inexpensive method.
