What is the News?
Researchers from Amity University (Haryana) have developed an N95 mask by using 3D printing technology.
What is the N95 Mask?
N95 mask (respirator) is a safety device that covers the nose and mouth and helps protect the wearer from breathing in some hazardous substances.
The ‘N95’ designation means that when subjected to careful testing, the respirator blocks at least 95 percent of very small (0.3 microns) test particles.
What has been developed?
Indian Researchers have developed an N95 mask by using 3D printing technology.
It is a four-layer mask whose outer layer is made up of silicon and has a shelf life of more than 5 years depending upon the use.
The mask is reusable, recyclable, washable, odourless, non-allergic and anti-microbial.
The mask can be used to prevent infections like COVID 19. It can also be used by workers in different industries where they are exposed to high volumes of dust like cement factories, brick kilns, cotton factories and pain industries.
