In today's world, rotors are key mechanical elements in many devices. They are most often found in engines, generators, pumps and turbines, where they convert energy from one form to another by rotating around an axis. It is important to realize that each rotor needs to be balanced for proper and long-term operation. The final assignment focuses on the balancing of rigid rotors and the production of a 3D printed device, with which we perform the dynamic balancing process. A 3D printed piezoelectric sensor is used as a force sensor. The work includes a description of the design and manufacture of the device using 3D printing technology, the calibration process and its use on a practical example. A simulation of the dynamic forces that appear at the bearings and a program that performs the balancing procedure and a test that verifies the success of the performed procedure have also been created. All program code is written in the Python programming language, 3D printing is performed on the Original Prusa XL printer, and all measurements are performed with measuring equipment from the Ladisk laboratory.
