Concrete printer now prints Covid-19 masks and open sources solution
27 March 2020
Italian company WASP, widely known for its development of 3D printingto produce a variety of prototype concrete structures, has developed a 3D printing process that customises coronavirus protection masks.
By 3D-scanning an individual face, and using the material PCL (polycaprolactone), a biomaterial that can be used for direct skin contact, a perfectly-fitting mask can be created in four hours.
The company says: “Our goal was to make the mask perfectly ergonomic, following the facial features as a second skin, a result that we obtained using Blender CAD-modelling software. ‘My face mask’ can be easily sanitised and reused many times, as the central part features a replaceable filter. Because it only takes about four hours to customise a perfectly fit face mask, this reduces skin irritation and long-use related issues.”
WASP has released the project in open source, with instructions and the .stl files ready to be downloaded from the link below.
