Design and Fabrication of 3D printed Open-source Ventilator to Save People’s Life in COVID-19 Global Pandemic
Project Description

According to the online COVID-19 statistics (, the global novel coronavirus pandemic (COVID-19) has resulted in 4 million confirmed cases and more than 280,000 deaths in more than 210 countries and regions. threatens to overwhelm the global medical infrastructure at the regional level causing spikes in mortality rates because of shortages of critical equipment, like ventilators. In recent development and widespread deployment of small-scale manufacturing technologies like RepRap-class 3-D printers and open source microcontrollers, mass distributed manufacturing of ventilators has the potential to overcome medical supply shortages. There are more than 10 groups in the world working on open-source ventilators. However, these ventilators have not been tested according to the industrial standard and/or the medical device guideline of US FDA.
