Porosity by Digital Design Center presents a research into the integrated design and fabrication approach of porous surfaces in architecture. The structure is fabricated out of foamed polystyrene by removing portions of its volume.

The process considers the utilization of a hot knife tool mounted as an end effector for an industrial robot, which vaporizes the sides of the cells, thus detaching it from the initial block. Such porous surface designs can be applied in response to building’s performances such as ventilation, insulation and air quality.
