3D printing is a rapidly emerging low-cost, high-yield, and high-speed manufacturing technique that has already been utilized in fabricating sensor and actuator devices. Here we investigate the cyclic fatigue and the effect of heating on 10 \times 10 mm2-sized, 3D-printed polyamide-based laser scanning electromagnetic actuators, which are intended for integration with miniaturized laser-scanning imagers to yield a wide variety of optical imaging modalities. The tested actuators offer compact sizes and high-scan angles, comparable to their MEMS counterparts. We have tested N = 15 devices, at 5 different total optical scan angles between 40° - 80°, and observed their lifetimes (up to 108 cycles ≈ 10 days each), as well as the variability in their scan angle and mechanical resonance. A selected scanner was also tested under increased temperature conditions up to 60 °C for 10 hours, showing no sign of fatigue when returned to room temperature. Overall, it is concluded that 3D printed polymeric actuators are promising low-cost alternatives for short-term use in disposable opto-medical imaging units.
