Academic and Technical groups used Cellulose Nanofibers for the production of durable 3D multifunctional monoliths
Despite technological advancement, the three-dimensional (3D) monoliths manufactured from organic substances lack physical customization and form accuracy, this limits their functionality in several practical applications. To overcome this hurdle, researchers attempted to use Cellulose nanofibers for manufacturing customizable and durable 3D monoliths. Cellulose nanofibers (CNFs) are attractive candidates as they are obtained from renewable resources which are easily available, consists of good biocompatibility, and supports various surface composition.
The conventional 3D printing of 3D monoliths is difficult to control making it hard to meet the criteria for particular situations. Hence, 3D printing employed a unique manufacturing method that implements a layer-by-layer process to instantly produce customizable 3D designs. Direct ink writing (DIW) is a method in 3D printing that exhibits an adjustable extrusion approach and simple operating mode. DIW can mix a wide variety of substances into inks and print them into geometric structures which is not supported by conventional 3D printing. But to obtain a viscoelastic ink with appropriate rheological behavior and optimizing the accompanying printing process is still a challenge when employing the DIW 3D printing technology to create 3D monoliths.
Finally, Elastomeric ink for DIW 3D printing was manufactured using cellulose nanofibers extracted from oil palm wood. The cellulose nanofibers display rheological characteristics and 3D processability, monoliths manufactured from cellulose nanofibers in this study have exceptional potential. A scaffold made of cellulose nanofiber shows a porous structure, outstanding mechanical characteristics, and low thermal conduction. Hence, the scaffolds manufactured can be used in various applications due to their renewability, customizable geometry, eco-friendliness, and form fidelity.
