Abstract

According to one embodiment, a custom medical mask formed for a particular user from a three-dimensional electronic model includes a body formed from a polymerized photopolymer material. An interior surface of the body is configured to seat on the particular user'"'"'s face and comprises a physical embodiment of a three-dimensional electronic model corresponding to unique facial features of the particular user. According to another embodiment, a method of creating a three-dimensional electronic model for use in forming a custom medical mask for a particular user includes scanning a portion of the particular user'"'"'s face using an electronic scanning device, generating a three-dimensional electronic model of the portion of the particular user'"'"'s face based on the scanning, and transmitting the three-dimensional electronic model of the portion of the particular user'"'"'s face for use in forming the custom medical mask for the particular user from a photopolymer using a stereolithography apparatus.
