Foster + Partners designs 90-second face shields to stem spread of coronavirus
The mask is made of three parts: a polythene visor, a headband and a silicone rubber head strap connecting them.
Foster + Partners estimates that each face shield can be laser-cut in less than 30 seconds, and assembled in a minute. It says it is able to make 1,000 masks a day with a single laser, which it says is a faster way of manufacturing than 3D printing.

The mask can be disassembled, cleaned, sanitised and reused, and the visors can be flat-packed for speedy distribution.
