JLR starts production of 3-D printed visors

JLR starts production of 3-D printed visorsWarwickshire-based Jaguar Land Rover (JLR) is turning over its prototype build operations to start production of protective visors for NHS workers to answer the Government call for more vital equipment to fight the coronavirus.

The only reusable, NHS-approved visor of its kind, the design has been developed in collaboration with a team of NHS healthcare professionals, for rapid prototype 3-D printing at the Advanced Product Creation Centre in Gaydon.

It comes as a national shortage of Personal Protective Equipment (PPE) for NHS staff on the frontline in the fight against COVID-19.

Through collaboration with companies such as Pro2Pro in Telford, the ambition is to produce 5,000 visors a week for NHS trusts around the UK.

Trials have already taken place with a team of healthcare professionals at the Great Western Hospitals NHS Foundation Trust and South Warwickshire NHS Foundation Trustprior to the commencement of production on 31 March.

Rapid prototyping technology has enabled the engineers to work through several iterations of the design in under a week, which has allowed for medical staff to five feedback and improvements to be made.

Engineers at JLR’s Additive Manufacturing Centre, who have designed and manufactured the visors, are now in discussions with suppliers and partners to scale-up production — they also plan to create a tool that will enable mass production.

It is the company’s intention to make the open source CAD design files available to additive manufacturers and suppliers, so many more protective visors can be 3-D printed over the coming weeks.

Each face visor has been designed to be reusable, and can be easily dismantled and cleaned before being used again; safeguarding NHS trusts against future shortages as the situation develops.

JLRBen Wilson, additive manufacturing and prototype design manager, said: “It’s been a real team effort, we have trialled different materials and improved the design over several iterations in consultation with real doctors and nurses on the frontline – this has allowed us to create something unique and truly fit-for-purpose.

“While this is a small effort, it is vital we help as many people as we can by utilising our resources.

“Collaborative teams working at JLR, along with the wider computer-aided design and 3-D printing community, will continue to do what we can to help healthcare workers.”

The clear shield is manufactured using chemically-resistant polycarbonate, which is trimmed down by RGH Rubber Ltd using a multi-cutter machine. Created using ‘state of the art’ laser sintering, jet fusion and FDM processes, the team went to particular lengths to ensure the cap top can be worn comfortably and safely for many hours.

A secure elastic strap – provided by Beacon Trimmings of Coventry – holds the visor in place, and this can be quickly and easily replaced to avoid contamination.

Dr Steve Iley, JLR’s chief medical officer, said: “It’s important we all use our skills, expertise and facilities to help protect NHS staff on the frontline during our country’s greatest crisis in a generation.

“We can all play a part in helping those who need it most.”

JLR 2The visors are assembled by a skeleton team of four JLR employees in a specially designed clean area.

Strict processes are in place to ensure there is no risk of contamination before the finished visors leave site.

JLR is working closely with the UK Government and has offered its research and engineering expertise, as well as digital engineering and design, printing of 3-D models and prototypes, machine learning, artificial intelligence and data science support.

As part of ongoing consortia, JLR will also support those providing vital equipment for ventilator development.
