The coronavirus pandemic has sparked a global scramble for face masks and
respirators. Most of the world's face masks are made in China and
Taiwan, which currently find it hard to satisfy demand, and scientists are
racing to find alternative sources. A team of researchers at the Czech
Institute of Computer Science, Robotics and Cybernetics (CIIRC) has
developed a high-grade respirator that can be printed on industrial 3D
printers or produced by injection molding technology.
