3D printing expertise called in for fight against COVID-19

The skills and expertise of the rail industry have not only been demonstrated in ensuring that the movement of people and goods is uninhibited during the corona virus (COVID-19) pandemic.

In Barcelona, railcar and signalling manufacturer Alstom has been utilising the knowledge of its industrial prototyping team to build visors for face shields and ventilator valves which are being delivered to hospitals.

The initiative is in partnership with 3Dcovid19.org which has been coordinating additive manufacturing facilities to provide parts for the healthcare sector in Spain.

“3D printing has gained prominence due to its particular usefulness for creating equipment to protect against COVID-19, as it can be used to manufacture materials currently suffering severe shortages such as face masks, mechanical respirators and even door openers, among others,” said Jaume Altesa, who heads Alstom’s 3D printing hub in Santa Perpètua, Barcelona.

“The aim is to help the healthcare community by manufacturing parts that meet appropriate quality and safety standard.”

Due to the rapid modifications enabled by 3D printing, developers and designers that previously produced parts for new trains have pivoted to making in-demand medical supplies.

At the same facilities, computer aided design (CAD) experts are working on portable personal protectors for door handles and incorporating new anti-bacterial materials in masks.

When not working on products to equip front-line health workers, Alstom’s 3D printing division works to make prototypes and 3D printed parts quickly and cost-competitively for new trains and for customers who require spare parts, while also facilitating manufacturing and maintenance operations. The company’s “Industry of the Future” programme is part of the Smart Operations initiative. Internally, 3D printing is used to make tools for factories, prototypes for design validation, rapidly made mould and series parts with roughly 70 references in plastic and metal.
