Part 4/5:
Made predominantly from crushed marble derived from quarry waste, the material is fabricated using 3D printing technology, which allows for the creation of porous structures that increase the surface area for moisture absorption by up to four times while using 60% less material.
Initial studies have demonstrated the efficacy of this invention. A 20 cm cube of the material was tested in the reading room of the municipal library in Porto, Portugal. In a scenario with 15 people and no ventilation, thermal discomfort was reduced by 75%. When employing slightly thicker blocks, this figure increased to 85%.
