The company used a modified version of its cochlea extruder, which features a rotating nozzle that permits a better deposition of fibres. The extruder allowed WASP to print a chair made of wood paste, a mixture made of liquid glue, flour and sawdust.
At the event, the company also experimented with mushroom mycelium, which is a 100% compostable material that is more resistant than concrete and the focus of many green building projects. WASP used this material to reinforce a structure.
