Can 3d printing die and plastic be realized on the same machine?

No way. At present, although some metal 3D printers also support a variety of materials, they can't print in 3D at the same time, and it takes a lot of preparation to change materials at a time. 3D printers are filled with different "printing materials" such as metal, ceramics, plastics and sand, which are real raw materials. After the printer is connected to the computer, the "printed materials" can be superimposed layer by layer through computer control, and finally the blueprint on the computer becomes a physical object.
