FACIAL MASK AND METHOD OF MAKING
First Claim
1. A facial mask comprising a first material and a second material and a material gradient in at least a portion of the mask, the material gradient transitioning from the first material to the second material, and a foam layer covering at least a portion of the second material in a region adapted for contact with the skin of a patient.

Abstract
Masks for various uses and methods for manufacture thereof, including masks for use in continuous positive air pressure (CPAP) therapies. An example includes a mask having a first, relatively softer material for contact with the face of the user, and a second, relatively harder or more structural material used away from the face of the user, with a gradient therebetween. The mask can be produced by additive manufacturing to avoid a discernible boundary between the first and second materials. The mask may include a foam element, which can be removable for replacement in some examples, for contacting the patient'"'"'s skin.

10. A method of manufacturing a facial mask, the method comprising:
-
obtaining a set of facial contours of a person'"'"'s face by one or more of digital photography, video, infrared, or laser scanning; optimizing a set of mask contours for an area where a mask will come in contact with the person'"'"'s face; and constructing a mask using an additive printing process including a first layer of a first material having first properties and a second layer of a second material having second properties and a material gradient between the first and second layers in at least a portion of the mask, the material gradient characterized by the lack of a discernable boundary between the first and second materials. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
