Bellus3D FaceMask Fitter
Bellus3D FaceMask Fitter
Bellus3D's Face Mask Fitter is a personalized 3D printed plastic frame that is contoured to the specific shape of a person's face to improve the seal of surgical or similar face masks. The mask fitter model can be generated with Bellus3D's face scanning app on an iPhone 11, iPhone X, or iPad Pro with FaceID capability.
The Loma Linda University School of Dentistry has worked with us on the development and testing of the Mask Fitter and have found that it enhances the peripheral seal of a mask.
If you are interested in directly ordering manufactured mask fitters, we have partnered with Protec Dental Laboratory to supply you.
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.
What You Will Need
You will need to scan the wearer's face using Bellus3D FaceApp, which requires an iPhone with a TrueDepth camera (iPhone X, Xs, Xs Max, XR, 11, 11 Pro or 11 Pro Max). If you are using an iPad Pro, you can scan using Bellus3D Dental Pro.
To 3D print the fitter, you will need a 3D printer using material such as PLA plastic.
Band Material: You will need material to create a band to hold the fitter in place around the head. We recommend a chain of thin rubber bands. It may also be possible to use elastic cloth or string.
Filter Material: A surgical mask is preferred. Other filtering materials may work with reduced effectiveness, such as cotton cloth.
What It Costs
Scanning with an iOS device and Bellus3D FaceApp or Dental Pro, and exporting the fitter as an STL file cost $2.79.
3D Printing of the mask fitter is available through Protec for a fee of $25.00 each
Scanning with Bellus3D FaceApp
- Download Bellus3D FaceApp from the Apple App Store
- 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.
- Launch the FaceApp application and select the FACE option.
- 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.
- 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.
- 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.
- 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.
