This mask design uses a 3D printed mold to create the bulk of the mask with a vacuum or thermoforming machine. Relatively few 3D printed parts are required for the mask which speeds up production time. The mask being made from a single sheet of PET plastic should be a better barrier than 3Dprinted plastic. This design is based on the "Montana Mask" design.
