///SPONG3D: Developing an integrated 3D-printed façade with complex geometries for active temperature control
Spong3d is an adaptive 3d printed facade system that integrates multiple functions to optimize thermal performances according to the different environmental conditions throughout the year. The proposed system incorporates air cavities to provide thermal insulation and a movable liquid (water plus additives) to provide heat storage where and whenever needed. The air cavities have various dimensions and are located in the inner part of the system. The movable liquid provides heat storage as it flows through channels located along the outer surfaces of the system (on the indoor and outdoor faces of the façade). Together, the composition of the channels and the cavities form a complex structure, integrating multiple functions into a singular component, which can be produced by using an Additive Manufacturing (AM; like 3D printing) technology.

For what it’s worth, the wireless transmissions of Wi-Fi communications are the same frequency which resonates water molecules. If your Spong3d surface includes (effectively) a wall of water then it might also function as a Wi-Fi curtain/barrier.
