Full-automatic 3D printing system based on gantry type variable dimensions

Abstract

The invention provides a full-automatic 3D printing system based on gantry type variable dimensions. The both sides of the top surface of a base are provided with a pair of symmetrical through slots separately, and each slot is internally provided with a vertical rod seat; the right and left sides of each vertical rod seat are provided with a ball screw a and a cylindrical guide rail b separately;the ball screw a penetrates through connecting seats, and is connected with a ball screw seat a; the lower part of each connecting seat is provided with three horizontal through holes, and the through holes in the both sides of each connecting seat are each provided with a cylindrical guide rail a internally; the through holes in the middle of each connecting seat is internally provided with a ball screw b; the connecting ends of the four cylindrical guide rails between the two connecting seats, and the connecting ends of the two ball screws b are connected with a nozzle seat simultaneously;the lower part of the nozzle seat is provided with a nozzle; and a rotatable platform is arranged at the position, below the nozzle, of the base, and the upper part of the rotatable platform is provided with a scalable printing platform.

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.
