Effects of Incorporating Ionic Crosslinking on 3D Printing of Biomass–Fungi Composite Materials

mycolabadmin

Researchers developed an improved method for 3D printing with fungal composite materials made from agricultural waste and mushroom mycelium. By adding sodium alginate (a seaweed-derived thickener) and treating the printed objects with a calcium salt solution, they significantly improved the structural integrity and precision of the printed parts. This technique addresses a major challenge in the field where printed objects would shrink and warp after printing, making it possible to create complex shapes from sustainable, biodegradable materials.

Extrusion-based additive manufacturing of fungal-based composite materials using the tinder fungus Fomes fomentarius

mycolabadmin

Scientists have developed a way to 3D print objects using mushroom mycelium (the thread-like structure of fungi) mixed with seaweed-derived alginate. These lightweight, spongy printed objects are biodegradable and have properties similar to polystyrene foam, but are made from renewable resources. This breakthrough could eventually replace plastic foam in packaging and other applications with an eco-friendly fungal alternative.

Challenges and Opportunities in Scaling up Architectural Applications of Mycelium-Based Materials with Digital Fabrication

mycolabadmin

Mycelium, the root structure of fungi, can be grown with agricultural waste to create building materials that are environmentally friendly and biodegradable. While these materials show promise for insulation and non-structural uses, scaling them up for large buildings faces challenges including lower strength compared to traditional materials and lack of standardized production methods. The paper reviews various fabrication techniques and existing projects to suggest how digital design and advanced manufacturing could help overcome these barriers.

Tailoring the Mechanical Properties of Fungal Mycelium Mats with Material Extrusion Additive Manufacturing of PHBH and PLA Biopolymers

Researchers have developed a novel method to make mushroom-based materials stronger by coating them with biodegradable plastics using 3D printing technology. This approach combines fungal mycelium from Fomes fomentarius with eco-friendly polymers to create composites that are significantly stronger than plain mycelium while remaining fully compostable. The resulting materials could be used for flexible devices, interior design, and other applications where both strength and environmental sustainability are important.

Researchers developed a new way to make fungal mushroom mats stronger by printing biodegradable plastic patterns onto them using 3D printing technology. The resulting composite materials combined the sustainability of fungal products with improved strength, making them suitable for flexible applications like smart textiles and lightweight parts. Both tested polymers (PHBH and PLA) enhanced the mycelium’s mechanical properties, with PLA showing superior strength improvements while PHBH offered home compostability.

Mycelial Beehives of HIVEOPOLIS: Designing and Building Therapeutic Inner Nest Environments for Honeybees

mycolabadmin

Scientists created experimental beehives made from living mushroom mycelium (the root structure of mushrooms) combined with 3D-printed scaffolds. These hives are designed to keep bees warmer while providing natural antimicrobial compounds that protect them from diseases. The research combines digital design technology with biology to create homes that mimic the natural tree cavities where wild honeybees live, potentially making them healthier and more resilient to climate change and diseases.

Structure-Forming Properties of Pleurotus ostreatus: A Promising Resource for Edible 3D Printing Applications

mycolabadmin

Low-grade oyster mushrooms, which normally go to waste due to cosmetic imperfections, contain valuable nutrients and compounds that make them excellent for 3D food printing. These mushrooms naturally possess properties like chitin and β-glucans that create the right consistency for printing edible structures. Using these discarded mushrooms for innovative 3D printing reduces waste, cuts production costs by up to 75%, and creates nutritious, customizable food products.

Binder Jetting 3D Printing of Biomass–Fungi Composite Materials: A Preliminary Experimental Study

mycolabadmin

Scientists have developed a new 3D printing method to create environmentally-friendly materials made from agricultural waste and fungi. Instead of using traditional plastic materials that take years to decompose, these biomass-fungi composites break down naturally. The new binder jetting printing process is faster and more precise than previous methods, making it more practical for manufacturing products like packaging, furniture, and building materials.

Fungal Innovations—Advancing Sustainable Materials, Genetics, and Applications for Industry

mycolabadmin

Fungi can be engineered to create sustainable, eco-friendly materials for construction, textiles, and packaging. Using advanced genetic tools and controlled growing conditions, scientists can customize fungal materials to have specific properties like flexibility or rigidity. These mycelium-based materials are biodegradable, renewable, and offer promising alternatives to traditional synthetic and conventional materials, helping reduce our dependence on petroleum-based products.
