Creating an ideal mask with a 3D printer

Abstract

With improvements based on the publicly available STL data of the mask⁽¹⁾, a mask that satisfies the following conditions was developed, eyeglasses will not fog, the skin does not get itchy, small suction resistance. The inhalation resistance of the mask was found to be proportional to the square of the flow rate, and it was found that the inhalation resistance of the developed mask was smaller than that of the commercially available masks.
