| Abstract Scope |
Fungal-based materials are biodegradable materials made of fungal cells. Such materials have already promising applications as sustainable packaging, for green leather, or for sound absorption. Being able to 3D print them would allow more design complexity and tailoring of the properties. However, one challenge is the stringent sterilization requirements. In this study, we fabricate fungal materials using direct ink writing in ambient conditions. An agar gel was chosen as the printing medium and supplemented with coffee grounds, malt and peptone to double the growth rate and density of the mycelium by Pleurotus ostreatus. The growth of the mycelium embedded in the ink was studied over 28 days and demonstrated that the mycelium was efficient in reinforcing the printed part, doubling its compressive modulus up to 60 kPa. Furthermore, the objects created by this ink exhibit self-healing and can be used for gluing components together. |
