Report that `` 3D printer saved the life of new coronavirus infected people ''

As of March 16, 2020, no cure has been established for a

new type of coronavirus infection (COVID-19) , and the treatment being carried out is symptomatic treatment to alleviate fever and cough caused by virus growth Is limited to It has been reported that 3D printers have solved such troubles at medical sites pursued by symptomatic treatment of COVID-19.

Because no cure has been established for COVID-19, it can be said that only 'the immune system in the human body' can treat COVID-19 at the time of writing. However, COVID-19 causes hypoxemia and damages the human body, so medical equipment such as artificial respirators are needed to make the immune system in the body fully operational.

With the spread of COVID-19 in many countries, Italy recorded 368 deaths per day, the highest ever recorded by COVID-19. Also in the country, Governor of Lombardy, Northern Italy, warned of lack of beds and respirators.

At a hospital in Brescia, Lombardy in such a whirlpool, an incident occurred on March 13, 2020, in which the 'valve' of a ventilator used for intensive care was broken. The hospital asked the ventilator supplier to supply parts, but the supplier had no stock.

Nunzia Vallini, a reporter in the local newspaper Giornale di Brescia who happened to cover the hospital, immediately contacted Massimo Temporelli, who is working hard to spread 3D printing in Italy. In addition to working as an Industry 4.0 promoter, Temporelli was a 3D printer expert who founded FabLab in Milan, a 3D printer workshop.

Temporelli has used his own network to find a person who can break this situation. Cristian Fracassi, founder of Isinnova , a 3D printer-related business near Brescia, arrived at the hospital with a 3D printer, and Fracassi opened the ventilator valve in just a few hours. I made it up. Below is a broken valve (left) and a valve made by Fracassi with a 3D printer (right). The size and shape are slightly different, but they were usable enough.

The 3D printer has continued to replicate the valve since then, and as of March 14, 2020 local time, it seems that 10 patients are using a ventilator using a valve manufactured with a 3D printer.

Lonati SpA, a machining manufacturer also based in Brescia, uses laser-based powder bed fusion to mass produce the valve in question.

According to the 3D Printing Media Network, which reported this news, `` How unknown how pandemics affect the global supply chain is, how 3D printers can contribute to the problems of the new coronavirus infection. It's not clear, but if the supply chain breaks down, 3D printing can help immediately. '
