Engineered Living Materials (ELM)

Biofabrication opens up new possibilities as a resource-efficient production system for so-called engineered living materials (ELM). These are biologically active structures based on living fungal cells that grow into predefined shapes. At Fraunhofer IGB, we use fungal mycelium as a promising material for a new generation of sustainable, bio-based composites that are biodegradable and made from renewable raw materials.

Fungal mycelium-based materials for a new generation of sustainable, bio-based composites

Engineered living materials (ELM) are functional materials that specifically integrate living cells into their structure, thereby acquiring active properties. If the materials are deactivated after shaping, e.g., by heating, the result is durable and inert components.

At Fraunhofer IGB, we are developing, in particular, fungal mycelium-based material systems that enable new functions through growth, self-organization, and material transformation. Materials made from fungal mycelium are biodegradable and can be produced from renewable raw materials. In combination with additive manufacturing processes, this results in structured, bioactive, and sustainable materials. 3D printing of the ELM enables free, precise design and faster prototype development.

3D-printed mycelium-based materials open up applications, for example, in lightweight construction, as biodegradable components, or in bioactive filtration systems.

Sustainability award for fungus-based 3D printed materials

 

At the 2025 Student Scholarship Award Ceremony at Hamm-Lippstadt University of Applied Sciences (HSHL), the first place in the Sustainability category went to Niklas Hug from the “Material Design, Bionics, and Photonics” program. For his bachelor’s thesis, he investigated the biointelligent optimization of 3D bioprinting processes for fungal mycelium composite materials. The practical work was carried out under the supervision of Dr. Achim Weber at Fraunhofer IGB.
