3D (three-dimensional) breathing mask and manufacturing method thereof

Abstract

The invention discloses a 3D (three-dimensional) breathing mask and a manufacturing method thereof. The 3D breathing mask comprises a pedestal, an interlayer and a face mask, wherein the pedestal is inosculated with a human face; the pedestal is uniformly provided with a plurality of small holes; the interlayer is arranged between the pedestal and the face mask; a filtering membrane is placed in the interlayer; the face mask is buckled on the pedestal; the face mask is also provided with a plurality of small holes; the pedestal, the interlayer and the face mask are communicated with external air. The face is scanned to obtain facial data by using a 3D scanner and a CT (Computed Tomography) scanner; a facial image is captured and converted into a 3D data file; a pedestal model digital file is generated; corresponding 3D pedestal and breathing mask digital files are designed; the printing is carried out through a 3D printer; the interlayer is placed in the pedestal; the face mask is buckled on the pedestal; a lacing is fastened. The 3D breathing mask provided by the invention is fayed with the face type of a person; the problem of the side leakage of air is solved; the propagation of a PM2.5 (Particulate Matter 2.5) and a pathogen can be effectively defended; a faying area to facial skin can be enlarged; the comfortableness is improved; the disassembly is convenient; a membrane is convenient to replace.

Description

technical field [0001] The invention relates to the field of masks, in particular to a 3D mask and a manufacturing method thereof. Background technique [0002] 3D printing is based on digital model files. First, it is modeled by computer modeling software, and then the built three-dimensional model is "divided" into layer-by-layer sections, and the printer is instructed to use powdered metal or plastic and other bondable materials. The technology of constructing objects by printing layer by layer. Commonly used materials are plastic, nylon, photosensitive resin, gypsum, titanium alloy, rubber and other materials. Currently commonly used printing methods include fused deposition modeling technology, selective laser sintering technology, multi-nozzle molding technology and three-dimensional printing. [0003] In 1986, Charles Hull developed the first commercial 3D printing machine, and this technology has experienced nearly 30 years of development [1]. It was first used to...

AI Technical Summary

Problems solved by technology

3D printing technology has been widely used in daily life and clinical treatment, but the application of 3D masks in daily life, disease control and clinical treatment has not been reported

However, due to the different shapes of people's faces, masks often cannot completely cover the face, so people often have side leakage of air during breathing.

Therefore, the above-mentioned masks cannot completely solve the problem of inhaling PM2.5 and pathogenic microorganisms
