Method of forming a custom mask using an impression mask

Abstract

A method of forming a custom mask (40) includes introducing a deformable material (32) to an impression mask (24) and directing the deformable material (32) against at least a portion of a user's face within the impression mask (24). This forms an impression of the user's face in the deformable material (32) to form the custom mask (40). The impression mask (24) receives the deformable material (32) and directs the deformable material (32) against at least a portion of a user's face within the impression mask (24) in response to pressure applied to the impression mask (24). The deformable material (32) may include a polycaprolactone polymer or an aliphatic polyester. The impression mask (24) may receive the deformable material (32) either before the user's face is brought within the impression mask (24) or while the user's face is within the impression mask (24).
