The construction industry, a significant contributor to global CO2 emissions, is in dire need of sustainable transformation. Emphasizing eco-friendly practices and a circular economy, this industry must minimize the use of non-renewable building materials. In this context, the development of biomaterials, specifically mycelium-based composites, presents a promising solution. These composites, made from the mycelial network of fungi, can transform bio-waste into high-end, biodegradable products with low carbon footprints. Designers and architects, in collaboration with scientists, are now exploring innovative uses of these biomaterials in construction.

This study delves into the potential of 3D printing technology to shape mycelium-based composites, offering a sustainable approach to manufacturing complex structures. Unlike traditional molding techniques, 3D printing allows for the creation of unique shapes with minimal waste, propelling the use of biomaterials in architectural applications. The research focuses on developing effective 3D printing workflows and mixtures using waste materials like paper and cardboard as substrates, emphasizing the need for controlled environments to manage the growth and form of these living materials.
One of the primary challenges in this process is contamination, which can hinder the growth of mycelium. The study explores methods to mitigate this issue, emphasizing the importance of maintaining sterile conditions throughout the 3D printing process. This approach not only supports the growth of mycelium but also contributes to the broader goal of reducing the environmental impact of the construction industry.
By leveraging the unique properties of mycelium-based composites and combining them with advanced 3D printing techniques, this research paves the way for more sustainable and environmentally responsible construction practices. It highlights the potential of biomaterials to revolutionize the industry, making a significant contribution towards a greener and more sustainable future in construction.
