The SFM-B is a custom-fit reusable respiratory mask based on the Stopgap Surgical Face Mask (SFM) Revision B design (https://3dprint.nih.gov/discover/3dpx-014168).

 

It is made using a Bellus3D face scan (created with the Bellus3D FaceApp or Dental Pro for iPhone X+ or iPad Pro with TrueDepth Camera) and a 3D printer to precisely fit a person's facial geometry.

 

Attached is one example that fits about 15% of the population. 

 

You can download the Bellus3D FaceApp (https://apps.apple.com/us/app/bellus3d-faceapp/id1352268131), scan your face and output a personalized STL to use on your 3D printer. 

 

The mask is in direct contact with the skin so please follow the instructions in the Documentation section regarding printing materials.
