Development of computerized technology for creating individual respiratory protection equipment using 3d modeling and cad

The development of individual respiratory protective equipment (masks) during the coronavirus pandemic is a pressing issue.Modern design and manufacturing technologies make it possible to create masks that account for the unique anatomical features of each individual.However, existing mask configurations often fail to consider the specific characteristics of the wearer.Therefore, it is critically important to design masks tailored to the anatomical features of each person.This paper examines the design process for protective masks using modern computer technologies and an information-based model.The general approach and practical options for mask design are presented, taking into account the individual's features.The information model comprises six main stages for creating a protective face mask.To design a human head form, the photogrammetry method is employed, allowing the creation of a three-dimensional head form from two-dimensional photographs.Using retopology tools on the surface of the 3D head form, the basis for the mask frame is developed in the 3DS Max program.Subsequently, a three-dimensional solid model of the mask frame is created.The process of generating the solid model and testing the mask frame under mechanical stresses, such as changes in facial expressions, is conducted in Autodesk Inventor.To enhance the mask's secure attachment to the face, a version with ear hooks, similar to those used in eyeglasses, is proposed.Additionally, the design allows for the use of one or two filters, as in the Pitta mask.An automation subsystem for mask design is developed in the iLogic environment of Autodesk Inventor, based on the results of this study.
