Over the past few days, we’ve been collaborating directly with a hospital to build a 3D-printable respirator mask with the following requirements: 

• Reliable seal around the face, even when moving around
• Uses HEPA filters
• Allows physicians to breathe easily
• Allows communication without being overly muffled
• Easy to print
• Reasonably comfortable for long periods of time
• Incorporates large straps for security and comfort
• Feasible to deploy from the community to the hospital in large numbers

Basic Parts/Supplies

• 3D Printer, Filament
• Elastic straps
• HEPA Filter (non-coated)
• Squishy gasket (we found this rubber foam gasket that’s super squishy and perfect. We contacted Frost King who said it’s non-latex, but call and double-check for yourself.)
