A helix-based 3D printing system

Abstract

The invention discloses a 3D (three-dimensional) printing system based on spiral lines. The 3D printing system comprises a base and a cylindrical thin wall, wherein the cylindrical thin wall is fixedly arranged on the base of a 3D printing machine; a plurality of spiral line-shaped tracks are uniformly arranged at the inner side of the cylindrical side wall; a bearing block is connected with a slide seat; the slide seat is arranged in the spiral line tracks; the slide seat slides along the spiral line tracks; a cylinder guide rail and a ball screw are arranged on the bearing block; a ball screw base is arranged on the cylinder guide rail and the ball screw; the ball screw base is connected with a connecting plate; one end of the connecting plate is connected with a spray nozzle through a rotation pair; a servo motor is used for driving the ball screw to rotate; the rotation of the ball screw enables the ball screw base to move on the cylinder guide rail, and enables the spray nozzle connected with the connecting plate to move along the radial direction of a cylinder, so as to perform printing. The 3D printing system has the advantages that the control on the 3D printing machine issimpler, the cost is lower, printing functions are complete, and the range of parts printed by the 3D printing system is broadened.

Description

technical field [0001] The invention belongs to the technical field of printers, and in particular relates to a helix-based 3D printing system. Background technique [0002] At present, the working structure of 3D printers is mostly a series mechanism, and the form of material forming is relatively simple. Most of the processing of the entire workpiece is realized by layer-by-layer forming. During its movement, the horizontal direction of the base does not change. Therefore, during the forming process , the angle between the nozzle and the plane of the base is always at a fixed value. Although this principle is simple and practical, it does not take into account the change of the printing direction when the arc or curved surface material is formed. When the material is printed layer by layer to form an arc or curved surface During the process (especially during the forming process of engineering plastic materials), since there is no change in the angle between the nozzle and...

Problems solved by technology

At the same time, the tandem mechanism of traditional printers still has disadvantages such as low control accuracy, lack of stability, high cost, and complicated control. This problem is especially obvious when facing high-precision forming.
