Coronavirus COVID 19: Michelin uses its 3D printers to make masks and respirators

In Clermont-Ferrand, the Michelin group has decided to make its workshops available in order to manufacture a part of protective equipment that caregivers are lacking in their fight against the COVID 19 coronavirus epidemic. Donations of masks, tires for emergency vehicles or the manufacture of FFP2 type masks launched on an industrial basis, the group is participating in the collective effort against the pandemic.

3D masks

Michelin has also launched 3 more original initiatives using 3D printing techniques, according to a group press release. The first is to print reusable masks: “In the context of a shortage of FFP2 masks, Michelin designs in partnership with the CEA (Central commission of nuclear energy) and other companies like Porcher, a 3D printed reusable plastic mask with an interchangeable filter. The prototypes were produced in 3D printing and the first productions are made in plastic injection with the support of the Michelin teams. We aim to have it approved at the end of the week for start of production next week. “ Michelin expects to be able to deliver the first 3D masks within 10 days. The company claims that 15 million such masks could be produced.

Flow sensors for artificial respirators

As part of the order for 10,000 respirators for the French State, Michelin also claims to work in partnership with Air Liquide, a company specializing in respirators. According to the company, Air Liquide is out of stock for a part for respirators, called a “flow sensor”. Michelin will be responsible for printing this missing part in 3D, for a manufacturing volume of 7,500 parts per week.

Sterilizable visors

Third and last initiative in 3 dimensions of the group: “Michelin has also just started to produce sterilizable polycarbonate visors for use in hospitals. We were very responsive, a call for help from Robert Debré hospitals in Paris and Edouard Herriot in Lyon came to us last Friday. “ Michelin claims to have set up production and to be able to coordinate the outsourcing of 10,000 to 20,000 masks next week.
