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