A prototype for a durable, lightweight, reusable face mask to augment the supply of face masks during the current shortage of PPE during the COVID-19 outbreak. The mask is provided “as-is” and primarily acts as a mechanical barrier. It is not a replacement for N95 masks.
Developed in collaboration with medical professionals, the mask prototype may serve in clinical and field use. If printed, used and maintained correctly, the mask provides a durable, reusable mechanical barrier.
The prototype provides four components: a contoured mask, filter housing, band clip, and ninjaflex comfort insert (optional)
No special tools are needed for assembly. The replaceable nonwoven filter materials recommended for the filter housing are widely available. Users will supply and install the elastic or cord.
The contoured mask may be more closely molded to the user’s face by submerging the edges in hot water and pressing it to reform the shape against the face.
Currently printing locally - any tips given via Paypal will be used for filament to continue making these as fast as possible.
1. DOWNLOAD FILES
Download the STL files for the masks and filter housing
2. IMPORT FILES
Import the mask, filter housing, and the optional flexible comfort insert. You may need to rotate
the mask and filter to print front down. Print with support.
3. PRINTING STRATEGIES
You know your printer best, however, we recommend:
• 20% infill with 0.3mm layer height and 2 shells
• PLA filament w. extruder temp (200°C – 215°C) and bed
temperature (0°C - 40°C)
• Print with a skirt and turn a fan on after the first layer
4. REMOVING PRINTED MASK
Pry off your prints using your hands or a flat tool like a paint
scraper. Make sure to angle the scraper shallow and tap lightly
so you don’t damage your print bed.
5. QUALITY CONTROL
Check the quality of your print, looking out for:
• Sturdy mask that doesn’t crack or break when held firmly
• Solid surface with little or no gaps
• Filter slides into mask with slight pressure and can be
removed by pushing against the grid from the other side
• Sand the sides of your mask to help with comfort
