The process uses inks made of particle-stabilized foams as templates for the creation of hierarchical porosity in the ceramics. By adjusting the rheological properties of the inks, the authors establish the printing parameters and sintering conditions needed to create the ceramic structures. The results show that the sintering temperature significantly affects the micropore size distribution, which affects the mechanical, thermal, and evaporative cooling properties of the printed structures. The study demonstrates that the use of clay in 3D printing can produce affordable and recyclable building materials with structural, insulating, and cooling properties.<\/p>\n\n\n\n<figure
