But some now fear they will no longer be able to help, due to new regulations brought in by the government to ensure equipment passes safety tests.
Kyle Millett - who repurposed his printers from making model planes to making PPE - told ITV News he is being forced to stop production.
"I can understand there have to be safety measures put in place and the visors and the equipment have to meet a certain standard," he said.
"But the visors we're producing on the printers are no different to the ones coming in from Turkey or China or anywhere else."
One of the people to have benefited from the visors made by Mr Millett is Sally Brice, Director of Mountbatten Nursing home.
She told ITV News the visors had helped "protect our residents".
Mark Roscrow, from the Healthcare Supply Association, says it is vital that PPE is key to the very highest standard.
He told ITV News: "I think it's important [...] a product that wasn't of the right standard - made by people who think they are helping - could be more detrimental".
