Jeremy Filko, a citizen from Virginia, United States, makes protective masks for medical workers by using a three-dimensional printing machine, or 3D Printer.
This was done voluntarily. He did not charge fees to the medical officers and the first emergency response officers who received them, even he even bore the costs of shipping.
Filko did this because the supply of N95 type masks used by medical personnel was experiencing shortages. As a result, medical personnel were forced to use the mask repeatedly. In fact, masks like that can only be used once.
Filko said 114 other people across America who owned a 3D printer had followed suit to make the mask.
