This paper presents the simulation and verification of a metallic and a 3D printed flexure for a fast steering mirror. Easy tuning can be important, because by adapting the stiffness of the flexure and thus the resonance frequency of the the system to the scanning application the energy consumption can be reduced. Since the required resonance frequencies change with the application, a flexible manufacturing process, like 3D printing is required. The experimental results show that the measurements of the aluminium flexure match with the simulation. Due to the printing process major deviations between measurement and simulation are observable for the printed flexure, such that a geometrical variation is performed to analyze the influence of the characteristic dimensions on the stiffness of the flexure. Measurement results show that with the arm width the stiffness can be well tuned. It is shown that the power dissipation can be reduced by a factor of 6.8, if the stiffness is adapted to the scanning application.
