An individual mask creation using the information model

Abstract

The development of individual respiratory protection (masks) during a coronavirus pandemic is relevant. Modern technologies of design and manufacture allow creating masks taking into account individual anatomical features of the person. The paper considers different types of construction of protective masks. It is necessary to create masks taking into account the anatomical features of the person. To address this issue, various countries are holding competitions to create a new generation of masks, such as the Mask Innovation Challenge in the United States. We offer creation of a protective mask with use of modern computer technologies on the basis of information model. The general approach and an option of practical realization of creation of a mask taking into account individual features of the person are considered. The information model has 5 main stages of creating a protective mask. To create a model of the human head, the method of photogrammetry is used, when its three-dimensional model is formed from two-dimensional photographs. On the surface of the head model in the program Autodesk 3DS Max created the basis of the mask frame using retopology technology. Then a three-dimensional solid model of the mask frame was developed, which was tested for mechanical loads when changing facial expressions. The creation of a solid model of the mask frame and simulation of mechanical loads were carried out in the program Autodesk Fusion 360. Fabrication of the supporting frame of the mask using additive technology is simulated. As a result, a mask is created using a replaceable multilayer filter. A further development of the work is the design of a reusable mask using different types of filters.
