3d printed face shields

I am raising money to print face shields and to purchase parts to assemble emergency ventilators using the designs from the open source ventilator project. I have already installed 8 printers and we are operating them 24x7.  I would like to install 30 more and purchase the plastic filament they use in order to print 15,000 face shields. This design has been tested by an independent laboratory and meets the ansi standard for splash and droplet protection.  Everything produced will be donated to our health care workers.
