Living Clay: Self-Healing 3D sculptures
Living Clay: 3D-printed Biodegradable Sculptures with Self-Healing Biomaterials
Living Clay transforms agricultural waste into biodegradable 3D-printed sculptures using self-healing biomaterials. Made from clay, rice straw, and prickly pear mucilage with mycelium, these artworks naturally integrate into urban and natural landscapes. As they decay, they nourish the soil, closing the loop of sustainability. A fusion of art, nature, and technology, Living Clay redefines public art as ephemeral, regenerative, and environmentally responsible.

Innovative Character of the Project
Living Clay redefines the intersection of digital fabrication, sustainable materials, and public art by introducing biodegradable 3D-printed sculptures with self-healing biomaterials. Unlike mainstream ceramic and bio-based projects, which often focus on either artistic expression or material innovation, Living Clay integrates both, fostering a novel approach to urban and natural landscape design.

Key Innovations Compared to Mainstream Practices:

Self-Healing Biomaterials: Traditional biodegradable sculptures degrade unpredictably. Living Clay enhances durability through microorganisms that mineralize calcium, strengthening the structure before decomposition. Additionally, prickly pear mucilage repairs microfractures, extending the sculptures’ lifespan.

Parametric and Organic Design: While most 3D-printed ceramics follow rigid geometric patterns, this project explores organic and parametric forms inspired by natural architectures, such as termite mounds and bird nests, to create structures that blend into their environment.

Circular Economy in Art & Architecture: Unlike conventional public sculptures that use extractive materials (concrete, metal, synthetic composites), Living Clay repurposes rice straw—an agricultural byproduct commonly burned in Valencia—reducing emissions while transforming waste into art.

Ephemeral, Site-Specific Art for Urban & Rural Spaces: Mainstream urban design prioritizes permanence. Living Clay proposes a new model of biodegradable, evolving sculptures that enhance spaces while naturally integrating back into ecosystems.

By bridging biotechnology, digital fabrication, and environmental sustainability, Living Clay establishes a groundbreaking framework for regenerative public art, setting a precedent for future urban and ecological interventions.
