Made of ink infused with the ceramic indium oxide, the 4cm monoliths are created by extruding the ink from a 3D printer – like squeezing toothpaste from a tube – and forming it into a lattice shape. Because indium oxide bonds with PFAS, the chemicals immediately stick to the monoliths and can be removed from the water in under three hours, which is compatible with current water treatment plants in the UK and abroad.
