Problems solved by technology

[0003] 3D printing technology is also revolutionizing the production of lightweight structures, wearable devices and flexible electronic components, but existing 3D printing technology is still difficult to print complex structures where multiple materials are fused together
[0004] However, most of the existing 3D printing can only achieve single-material printing, and it is difficult to achieve macro/micro cross-scale manufacturing
Developed multi-material 3D printers such as Stratasys Objet500Connex33D and J750 printers, Voxel8's multi-material 3D electronic printer, 3D Systems' multi-material composite 3D printer PROJET 5500X, etc., have the following shortcomings: First, the printing resolution is still low At present, it is difficult to realize the printing of micro-scale structures, especially the macro/micro/nano multi-scale and cross-scale manufacturing; the second is that the multi-material mixing basically adopts the passive mixing method of materials, and the mixing efficiency i
