Problems solved by technology

[0003] At present, the advantages of 3D printing technology are concentrated in the field of industrial design, and the advantages in the field of building materials are becoming more and more obvious. 3D printers use building materials as raw materials, and adopt digital modeling and layer-by-layer printing methods to meet various conventional or special-shaped buildings. The production and manufacturing needs of the wall, but the current 3D printing building materials have technical problems such as heavy weight, poor structural stability and high cost, which limit the application
