Russian chemists have developed a 3D printing technology using cheap natural materials based on cellulose. Based on the new technology, the finished products can be printed virtually from water and air, without polluting the environment.
3D printing allows for a short time to create finished products of any complexity from computer digital models. Researchers from the Institute of Organic Chemistry named after N.D. Zelinsky RAS synthesized a unique PEF material, which makes it possible to carry out three-dimensional printing cheaply and environmentally. The peculiarity of this material is that it is obtained from a natural substance – cellulose, which belongs to the category of the most promising renewable resources. In nature, cellulose is synthesized from carbon dioxide and water, available in the atmosphere in almost unlimited quantities. The source of energy for this reaction is sunlight.
The resulting polymer showed high chemical stability, it is not oxidized, is resistant to the action of chemical solvents and does not decompose, being in the natural environment. Moreover, it can be used many times. Products made from such a polymer will be quite durable, and additive technologies, such as 3D printing, allow you to create an object of almost any complexity.
“It is important that the resulting material can be repeatedly regenerated and reused. At the end of the life cycle, the 3D printing product can be converted to carbon dioxide and water by burning, and then again to obtain cellulose through the photosynthetic system of plants. A closed carbon-neutral cycle does not pollute the environment, it is based on cheap natural resources and can be conducted an unlimited number of times, “the authors of the paper note.
