Problems solved by technology

[0002] At present, the working structure of traditional 3D printers is mostly a space-orthogonal structure, and the form of material printing and forming is relatively simple, and the printing method of plane layering is mostly used to realize the printing work of the entire printed part.

At the same time, the movement form of the nozzle in the traditional 3D printer is that three independent servo motors drive the orthogonal ball screw movement in the three-dimensional space, and the printing movement of the nozzle is realized by the movement of the ball screw seat. Its main mechanical structure is three There are two orthogonal linear cylindrical guide rails, but there must be displacement restrictions at both ends of the linear motion structure along the linear guide rail, so that the printing range of traditional 3D printers is limited, so that traditional 3D printers cannot adapt to more printing conditions.
