The supply of valves needed to connect the breathing helmets to the oxygen cylinders was running out. The manufacturing company overwhelmed by the orders could not have supplied them in a short time, given that the stocks have long been exhausted.
The 3D printed valves
So through a request for help launched by the local newspaper il “Giornale di Brescia”, the idea of printing the valves in 3D was proposed thanks to Cristian Fracassi (CEO) and Alessandro Romaioli (mechanical engineer) of Isinnova a young engineering company from Brescia.
The engineers went to the hospital to understand what was needed and to pick up the valve. The valve was measured, dimensioned, redesigned in Cad software and finally, 3D printed. First with an Anicubic PLA filament printer and then with a powder SLS technology which was made available by the Lonati Group.

24 hours after the first valve was ready, the tests gave positive results and on the following morning another 100 valves were delivered.
