3D printing is a process of making a three -dimensional solid objects from a digital file using additive manufacturing techniques. In this process layers of material are successively deposited one above the other to create an object. Each layer can be visualized like thinly sliced section of the object. The key to this 3D printer is the thermoplastic extruder which is coupled with a Cartesian XYZ platform. 3D printing by using PLA filament electronics are based around the popular Arduino development platform,utilizing a custom made board for interfacing with the Arduino development Board and allowing stepper motor and extrusion temperature monitoring and control. In very simple terms,3D Printer (not to be confused with printers we see in everyday life) is electromechanical device that builds physical object with very high precision(100 micron or .1mm) at a very low cost. https://www.ijiert.org/paper-details?paper_id=140146
