The Applications of Nanocellulose in 3D Printing

3D printing was originally intended to realize mass production of various merchandise more conveniently and precisely, and it has achieved partly up to days. However, nowadays 3D -printed products still have some flaws, like inadequate shape stability and low printing precision. Meanwhile, nanocellulose, as a renewable natural material, is reckoned one of the most promising selections. This paper mainly highlights the utilizations and functions of nanocellulose in 3D printing. First, this paper offers a brief introduction concerning its structure, properties, and synthesis. Then, several practical applications in different domains are listed and anatomized to exemplify the necessity and superiority of the integration between nanocellulose and 3D printing. Moreover, this paper points out and generalizes some existing challenges and directions about 3D printing development and nanocellulose applications. Finite range of materials for printing still severely restricts the quality and performances of end-product. Lack of detailed standards to regulate and unify sources, dimensions, extraction and processing methods contributes to the miscellaneous specifications of nanocellulose. Consequently, consistent and profound refelction on cutting-edge technology and materials is essential for mankind and can also inspire us to utilize them in more rational, efficient and eco-friendly ways. The future of 3D printing and nanocellulose is still promising and anticipated to cover more industry by the integration with traditional manufacture.
