Face Visors: 3D Printing

🔗 3D Printed

sing Overhead Projector film in A4 format, holes easily made by a regular hole puncher. DOES NOT PROTECT against inhalation.

Face Visors: other methods

🔗 Face shield for mass production by lasercutting

Surgical Mask
Type 1: Single Layered
Type 2: Multi Layered, no droplet protection
Type 3: Multi Layered mask and droplet protection for the face. 



Can we create an open standard for DIY Surgical Masks and get it WHO approved? 

  1. Reduce pressure on suppliers - Allows manufacturers to focus on supplying medical professionals with N95s as they need it more. Other workers like grocery store employees should have priority access to official surgical masks supplies.  
  2. Decrease and delay transmission between people - COVID can be asymptomatic. Researchers across the world are asking people to flatten the curve so that health systems don’t collapse.Social distancing and hand washing are essential but there are still individuals who are not adhering to these recommendations.But increasing the COVID mindedness of the public can reduce the number of people doing this
  3. Developing countries will need access to solutions they can build in-country when supplies run out. We need to equip the Dilip Mahalanabises (a doctor who created onsite treatments for Cholera when imported supplies ran out) of COVID. If countries like the US (have) about 1 percent of the 3.5 billion respirators that experts estimate the health-care system needs a year to fight a severe influenza pandemic.’ what about poorer ones
