Engineer Invents "Lightest" 3D Printing Materials

[China Packaging Network News] Recently, Chinese and American engineers jointly invented a "lightest" 3D printing materials.

It is reported that this latest invented graphene aerogel was evaluated by the world Guinness Book of Records as the world's lowest density 3D printing structure.

According to foreign media reports, the graphene aerogel weighs only 0.5 milligrams per cubic centimeter. A small piece of square 3D printed graphene aerogel can be easily hung on a single wheat aroma without bending it (as shown Shown).

It is understood that graphene is considered to be the thinnest material in the world, with extremely physical and electronic properties. It is a monoatomic layer structure in which carbon atoms are combined in a hexagonal manner. 3D printing graphene technology is very difficult, but engineers have invented a simple printing method that uses only graphene oxide and chilled water.

It is understood that engineers use a modified inkjet printer with two nozzles to print 3D printed graphene aerogels of various shapes with a small amount of raw materials. Droplets of 3D printed graphene oxide and water are placed on a condenser plate in a freezer at minus 20 degrees Celsius to produce a 3D ice structure of graphene and chilled water. Graphene can retain itself in the ice structure. shape.

After printing is complete, the 3D printing material is placed in a freeze dryer for deicing. The final 3D printed graphene aerogel can maintain its shape at room temperature.

It is reported that this 3D printed graphene aerogel is assisted by Dong Lin, Assistant Professor of Industrial Manufacturing System Engineering, Kansas State University, Chi Zhou, Assistant Professor of Industrial Manufacturing System Engineering, State University of New York at Buffalo, and Qiangqiang Zhang, Associate Professor of Lanzhou University, China.
