Introduction:

Nowadays 3D printer become more popular in industrial, medical…Recognizing the profound implications of 3D printing for the future of design and manufacturing. Industrial Electronics Department has designed 3d printer based on RepRap 3D printer model to prepare students for current and emerging careers in those fields. 3D printer was designed with a high-end Arduino board that permit high speed moves without any loss of quality. Indeed, the Arduino board, running at 96Mhz, enables a smoother calculation to control mechanical system.
