Piezoelectric Pneumatic Valve
thingiverse
A prototype electric valve designed for printability is in the works. After testing and fine-tuning, I may redesign it for better airflow and faster printing. The piezo transducer should flex upwards to create a .1mm gap, allowing air to escape. My future plans include using this to power a Wobble Ring Stepping Motor (http://www.thingiverse.com/thing:33853). Imagining a steam-powered RepRap, I designed the valve around a 20mm wide piezo element from SparkFun (https://www.sparkfun.com/products/10293). To enhance printability, I borrowed Whosawhatsis' teardrop hole code (http://www.thingiverse.com/thing:3457). Seeking advice on improving throughput and sealing the valve without leaks, this is my second design. All feedback is appreciated.
