Scientists from Morriston Hospital in Swansea have created pioneering technology to help survivors of acid attacks and burns.
They are using 3D printing to custom make masks which patients with facial burns can wear for up to a year to reduce their scarring.
Several masks will be made for patients as their face develops.
The new technology has meant patients are able to avoid a more painful procedure, which would involve general anaesthetic for children.
Lab services manager Peter Llewelyn Evans said the next step for them would be to have a specialist centre at Morriston Hospital.
