The 3D printed facade bricks were developed using a custom clay mix composed of iron-rich clay, water, recycled ceramics, and filler materials such as Wonderlime—a sustainable additive developed by Eggxpert. This formulation minimizes shrinkage during drying and firing, allowing for precise, large-scale ceramic printing with minimal deformation.

Designed with integrated pockets to host greenery and redirect rainwater, the bricks contribute to passive cooling and promote urban biodiversity. Fired at a high temperature of 1220 °C for enhanced strength and durability, their interlocking geometry enables mortar-free assembly and easy disassembly—supporting circular construction principles.

This facade prototype was developed as part of Victoria Roznowski’s Master’s Thesis in Architecture at TU Berlin in 2024, under the supervision of Prof. Ignacio Borrego.
