The 3D printed framework uses mobile face scanning technology by Bellus3D™ to create a custom mask fitter for use with standard procedural masks. Download the app to get started!

In order to process your mask, all scans must be sent from the Bellus3D FaceApp. If you are using an iPad Pro, you can scan using Bellus3D Dental Pro. (At this time, Bellus3d FaceApp is only available on the iTunes App Store). Use the FaceScan setting. It’s the option in the app, on the bottom left corner. Frameworks will not be processed until payment is received.

Warning: While our fitter seems to improve the seal of a face mask, it has not been tested for effectiveness in preventing COVID-19, and you should use it at your own risk.

  1. Download Bellus3D FaceApp from the Apple App Store
  2. Stand or sit in a stationary place so that you will be able to turn your head 90° to the left and right when you are ready to scan. Remove glasses or anything else obscuring your face.
  3. Launch the FaceApp application and select the FACE option.
  4. Position the phone directly in front of your face at a distance that causes the red oval to turn green. Once the oval turns green you can push the white button at the bottom of the phone display in order to initiate the scan. Hold a neutral facial expression (don’t smile) for the duration of the scan.
  5. The application will prompt you to turn 90° to the left, then back to the middle, 90° to the right and then back to the middle.
  6. Once the capture is complete, FaceApp will stitch together the various perspectives to form the 3D model. In the bottom right corner, you can press the “Mask Fitter” button to generate the fitter model.
  7. Press the “export” button in the bottom right to send the .stl file to your computer. You can do this by choosing the email option, and then opening the mail with the .stl attachment on your computer.

  1. After printing the fitter, remove any extra support plastic and sand the surfaces so that they are smooth. Avoid breaking the hooks that are used for holding the bands.
  2. Create an elastic band and attach it to the fitter. If you are using thin rubber bands, you can attach them to the hooks, and then make a chain to create a band that fits around the head.
  3. If using a surgical or face mask, put on the mask first. If using unsecured material like a cloth square, you can hold it in place over your face.
  4. Put the fitter over the mask, and check in the mirror to see that it matches the model in the app. If fitted properly, the mask material should move in and out when you breathe, and minimal air should escape around the edges of the fitter.
  5. When taking off the fitter, carefully remove it while avoiding contact with your eyes.
  6. The fitter can be reused, but should be thoroughly sanitized by submerging it in a disinfectant solution. Some 3D-printed materials may be porous and more difficult to sanitize.
