Design studio Unfold, based in Belgium, created a ceramic filter for an open source water boiler and purifier to be used in the developing world. The reason I’m writing about this is because the ceramic filter was 3D printed.
How was it made? This machine was first designed by Jesse Howard in collaboration with Thomas Lommée as The WaterBoiler. This design was passed on to Unfold who adapted the design by replacing the PET bottle with a cut through glass bottle holding the 3D printed ceramic water filter.
