A team from the University of Edinburgh has designed a system which generates 3D images of participants’ faces using either a precision scanner or three pictures taken with a smartphone.
From this, moulds can be created that precisely match the contours of an individual’s face. The moulds can be 3D-printed and used to make mask components made of silicone, with the final product assembled using additional plastic parts and a filter section.
While masks could be made using scanners or smartphone images, being able to capture pictures remotely is particularly beneficial during the pandemic due to social distancing rules and the ubiquity of remote working.
