Plant-based nanocellulose, due to its excellent mechanical properties and rheological characteristics, is suitable for 3D printing technology, effectively enhancing material strength and printability. Its natural origin from plants also makes it capable of meeting the safety requirements for raw materials in the food industry, thus possessing great development potential and significant application value in the field of food 3D printing. 3D printing CNF-reinforced filaments will exhibit a 30-35% increase in strength compared to regular PLA 3D printing filaments。
