Medical Face Shields – 3D Printing
Helping the Medical Community – Have a 3D Printer? Medical Face Shields during the Th COVID-19 outbreak continues to expand globally. Information from healthcare organizations say that some distributors have placed certain types of personal protective equipment (PPE) on allocation, therefore, Basing the quantity of Medical Face Shields available to the healthcare organization on previous usage, not projected use. This formula greatly puts the front-line health workers at great risk. Medical Face Shields simple in design, produced and assembled by hobbyists on their own home 3D printers. Searching for a way to help the medical workforce? Already have a 3D
