3d Mask, 3D Printed Respirator

3D printed mask design, coupled with 2 types of filter media and elastic headbands to form a face-fitted Level 3 Respirator/Surgical Mask.

The filter media is autoclaved Halyard H600 Surgical Wrap (2 layer material, droplet impermeable) as the external layer. Underneath that are 2 layers of 3M Filtrete MPR 2800 Ultrafine Furnace/AC Filter. These two types of material are cut into circular cutouts 6" in diameter, then placed over the lip of the mask. The filter media is then secured with a zip tie for tight fit. The STL files allow for 4 sizes of prints to fit a variety of face shapes, XSM, SM, M, L. These masks meet or exceed requirements for Level 3 Surgical masks and protect from both droplets, splashes and airborne particles, in addition to providing a much more tailored fit than standard surgical masks.

Pre- and Postprocessing Instructions

Postprocessing - the masks are more comfortable and cause less skin irritation with a thin silicone coating along the edge. The outer .5" edge that rests against the face can be dipped in liquid silicone and allowed to dry for 24 hours. The upper elsatic strap is cut to 12" and the lower strap cut to 10" before securing both to the strap loops on each side.

Filters - We used a laser engraver/cutter to quickly cut the filter media into 6" diameter circles. These are layered with the Halyard H600 surgical wrap (twp layers: blue + white) on the outside and 2 layers of the Filtrete 2800 AC filter underneath. After placing these over the front edge of the mask a ziptie longer than 12" is used to firmly hold down the filter media over the circular lip. This ziptie creates a tight seal against the edge of the mask. The filter media can be trimmed to fit so that it does not impair the users line of sight.

Reviewer Notes

Dear author,

In order to proceed with your submission, we need to make sure specific print instructions are included in your design for users to properly recreate the model.

Please include best printing parameters for your design and update the submission at your earliest convenience.

Additoinally, we request to change the name and remove "respirator" from the title.

Sincerely,

VA REVIEW TEAM
