Additive manufacturing, commonly referred to as 3D printing, has brought about a transformative impact on diverse industries, including construction, by facilitating the creation of intricate structures with heightened precision and efficiency. The incorporation of clay into additive manufacturing processes emerges as a promising avenue for advancing sustainable construction practices, characterized by diminished material wastage, augmented design adaptability, and the capacity to produce elaborate and personalized architectural components. Furthermore, this approach contributes to a reduction in environmental impacts compared to traditional materials, which emit fossil CO2 during their production. However, various studies remain necessary to explore the mechanical performance of earthen construction materials comprehensively. To address this issue, clay materials often benefit from reinforcement with different types of fibers which can enhance the structural integrity and overall performance of clay-based composites. For this purpose, the current research focuses on studying the mechanical behavior of clay materials reinforced with wood and hemp fibers. The study evaluates physical, chemical, and mineralogical attributes, along with microstructural properties and mechanical performance. The aim is to develop tailored specifications for 3D printing, overcoming constraints and advancing understanding of clay-based composites.
