Problems solved by technology

For example, for the existing three-dimensional printing technology of metal or ceramic printing, it is basically to spread a layer of printing material powder, and then carry out laser sintering or organic bonding of each layer of graphics according to the procedure to complete the printed layer. After sinking down, spread a new layer of printing material powder, and cycle in turn, so it is difficult to complete printing of different materials on the same plane
For the 3D printing technology of organic solutions, such as stereolithography, the principle is that the laser beam continuously scans the surface of the liquid photosensitive resin according to the layered data under the control of the computer. The next layer, cycled in turn, can only complete 3D printing of one organic material
At present, there is no 3D printing method that can well support the simultaneous printing of different components of ceramic materials or metal materials on the same plane, as well as the mixing of ceramic materials and metal materials, thereby forming a composite material composed of different ceramic components or metal materials. Composition or a three-dimensional structure in which ceramics and metals coexist
