Personalized 3D Printed Frames Improve Seal of Face Masks

The Bellus3D Mask Fitter frame is a personalized 3D printed plastic frame that is contoured to the specific shape of a person's face to improve the peripheral seal of surgical, KN95 or other masks. The frame is automatically generated from a 3D face scan using the Bellus3D Face App or Dental Pro app for Apple iPhone X, iPhone 11 or iPad Pro with FaceID capability.

The NIH has listed the Bellus3D Mask Fitter as appropriate for clinical use.

The Loma Linda University School of Dentistry has worked with us on the development and testing of the Mask Fitter and found that it enhances the peripheral seal of a mask.
