Additive Manufacturing using 3d Printer

3D printing is an additive manufacturing process in which 3D products are printed using the help of CAD (computer aided design) software. There are a variety of processes used to carry out 3D printing like FDM (fused deposition method), SLS (selective layer sintering), DLP (digital light processing), etc. The process adopted by us is FDM where we use different materials like PLA (polylactic acid), ABS (acrylonitrile butadiene styrene), etc. Any of these filament materials is chosen and deposited layer by layer after heating it up to its melting point. When several layers like these are combined, we get a final 3D printed product. In this report we focus on design of a 3D printer that uses up dimensions of 340*340*420 mm. It is also very economical. We make use of the 4-axis concept where one axis is the extruder and the other 3 are axes are x, y and z respectively
