The earliest 3D printing manufacturing equipment was developed by Hideo Kodama of the Nagoya Municipal Industrial Research Institute, when he invented two additive methods for fabricating 3D models. In distinction to the traditional methods of manufacturing where in the raw material is fabricated to the final product based on subtractive principles, these Additive manufacturing processes are based on additive principle for the part manufacturing. Different Additive manufacturing processes use different methodologies of adding up the material to form the final product. Advantages like manufacturing complex geometries, zero tooling along with no human intervention, manufacturing in single set-up etc., are few of them. Additive manufacturing (AM) was developed initially as a technique for rapid prototyping, to visualize, test and authenticate a design, before end- user production of the design. In recent years, Additive Manufacturing (AM) technique Fused Deposition modeling (FDM), has developed to become a rapid manufacturing technique because of the ability to produce complex parts layer-by- layer in lesser production cycle time than as compared to conventional machining processes. During the last decade, Additive manufacturing has attracted huge attention in various industries ranging from manufacturing, medical, automotive concept development etc., in developing products to meet the expectations of both the designers as well as manufacturers. Fused deposition modeling (FDM) is one among those most popular Additive manufacturing technologies where in the filaments are added one beside other forming a layer, and then layer upon layer to build the final product. Besides the simplicity of operation like ability to fabricate parts with locally controlled properties with varied materials, fused deposition modeling has resulted in manufacturing parts not only for prototyping but also functional parts. Keywords-AM,FDM,3D Printing I INTRODUCTION Fused deposition modeling (FDM) is a process for developing rapid prototype (RP) objects by depositing fused layers of material according to numerically defined cross sectionalgeometry. The quality of fused deposition modeling produced parts is significantly affected by various parameters used in the process. The object to be built is modeled using a Computer-Aided Design (CAD) software package. Solid modelers, such as Pro/ENGINEER, tend to represent 3-D objects more accurately than wire- frame modelers such as AutoCAD, and will therefore yield better results. The various CAD packages use a number of different algorithms to represent solid objects.To establish consistency, the STL (stereo- lithography), the first RP technique) format has been adopted as the standard of the rapid prototyping industry.A structure support base is positioned on an elevator structure and immersed in a tank of liquid photosensitive monomer, with only a thin liquid film above it. A UV laser locally cross-links the monomer on the thin liquid film above the structure support base.Additive manufacturing method where the cross section of the detail is cut into a thin material which is then successively glued to the previous layer and cut to shape with a knife or laser cutter. Objects printed with this technique may be additionally modified by machining or drilling after printing.
