In this work, a scara robot type 3D printer system is dynamically modeled and position control of the system is realized. For this aim; computer aided design model of three degrees of freedom robotic system is created using SolidWorks program then obtained model is exported to MATLAB/SimMechanics software for position control. Also mathematical model of servo motors used in robotic 3D printer system is included in control methodology to design proportional controllers. Uncontrolled and controlled position results are simulated and given in the form of the graphics.
