Some 1,400 3D-printer owners have pledged to use their machines to help make face shields for the NHS.
The BBC reports that the 3DCrowd UK group was started by palliative-medicine doctor James Coxon, and is now looking to recruit more volunteers.
It says thousands of its 3D-printed masks have already been made and donated to hospitals, GPs, pharmacies, paramedics and social-care practices.
Healthcare workers say they are having to put themselves at risk because of a lack of personal protective equipment.
“We are basically asking all the people around the country with 3D printers to join our project to create face shields for hospitals and other health workers,” said Gen Ashley from 3DCrowd UK.
