N2 - The construction sector is undergoing a deep transformation driven by digital transition, with increasing interest in advanced technologies such as 3D printing. In the path towards ecological transition, the integration of this manufacturing process with low environmental impact materials like raw earth has opened new opportunities for developing sustainable and high-performance building components. This study presents a parametric design workflow for raw earth blocks, featuring an internally optimized infill based on the use of generative geometries. Specifically, the infill is realized with triply periodic minimal surfaces, renowned for their high mechanical properties. The proposed workflow aims at enhancing the mechanical performance of these blocks, ensuring both structural efficiency and sustainability. The final part of the study involves the prototyping of the blocks using 3D clay printing is presented, serving as a tool for validating the proposed design and production process.
