In the fight against the COVID-19 outbreak, our country is facing the severe challenge of PPE shortage for the front-line health providers and essential workers. We launched a project to produce face shields using our home 3D printers on 3/27/2020. In five weeks, we have delivered over 3000 face shields to 70 hospitals in San Diego, Los Angela, New York and Tijuana. we encourage everyone to contribute their time and expertise to produce face shields and masks. Please take a look at what we are doing and how you can help.
