KOHLER, an American manufacturing company, best known for its plumbing products, has collaborated with Daniel Arsham, a contemporary, New York-based artist, to create Rock01 – a 3D printed sink created using paste-based pneumatic material extrusion. Extrusion-based additive manufacturing (EAM), often used for the rapid production of metals and ceramics, works by extruding the metal or ceramic material in solid powder form and mixing the powder with an expendable viscous fluid. In this case, pneumatic extrusion nozzles were used.
