In recent innovations within the building industry, 3D printing is a particularly advantageous technology, offering both cost-effectiveness and rapid construction capabilities. Consequently, the building industry continues to make technological improvements and has recently introduced nanocellulose 3D printing to create a more environmentally friendly future.
Greener Future of the Construction Industry
Using three-dimensional printing to manufacture building materials has been praised for its positive environmental impact. Less formwork or models could save you money on materials, which is one of the benefits. In addition, when products are manufactured on-site, there is a reduction in the amount of energy consumed for transportation and other activities associated with distribution.
Although there are cost reductions associated with 3D printing, the embodied energy of such materials might not substantially differ from that of conventionally manufactured goods. For instance, concrete and steel's most substantial environmental impacts are related to the material processing before they are cast or molded. With environmental performance as the principal consideration, researchers have investigated alternative feedstocks for 3D printing.
Thus, a candidate that exhibits promise is nanocellulose. Cellulose, along with hemicellulose and lignin, is an essential natural biopolymer and a component of sustainable materials found in the cell walls of agricultural biomass. These components afford the plant sufficient strength and stability. However, this approach to producing novel biologically based goods has significant consequences for the lifespan of the products. The natural biodegradation of nanocellulose, in contrast to the biodegradation of many other building materials, such as steel or glass, causes it to reach the end of its helpful life more rapidly than its abiotic counterparts.
Advancements of 3D Printed Nanocellulose
The most significant benefit of 3D-printed nanocellulose is the amount of resources that may be obtained from forestry, agriculture, paper mills, and straw wastes from agriculture, which can be received from various sources. The energy efficiency of the room-temperature pneumatic 3D printing method is enhanced by the absence of dies and casting forms. Because of the shear thinning features of nanocellulose hydrogel, the method no longer requires heat. Applying air pressure makes it printable and melts into a liquid state. Following the release of the pressure, the workpiece will continue to maintain its shape.
Based on the study conducted by Persistence Market Research, the global market for 3D-printed nanocellulose is estimated to be worth $16.5 million in 2022. It is anticipated that this market will experience considerable growth at a rate of 15.1%, reaching $77.5 million by the year 2033.
Regarding healthcare innovation, nanocellulose manufactured via 3D printing stands out since it provides a novel approach to medical solutions. Produced from organic matter such as plants and wood, nanocellulose exhibits distinctive characteristics that render it a highly viable candidate for many medical applications.
The strength, biocompatibility, and biodegradability of nanocellulose significantly influence the development of customized solutions in 3D bio-printing. This convergence facilitates the fabrication of complex and accurate frameworks, expanding the potential applications for customized drug delivery systems, medical devices, and tissue engineering.
Because of its biocompatibility, nanocellulose is utilized in scaffolds that simulate natural conditions for cell growth, demonstrating that it has the potential to advance regenerative medicine. Accordingly, fabrics composed of nanocellulose are highly suitable for expediting the healing process of wounds due to their exceptional flexibility and high absorbency.
