Material output device of 3D color printer

Abstract

The invention discloses a material output device of a 3D color printer. The material output device of the 3D color printer comprises a rotary plate motor and a motor rotation shaft, wherein a color conversion plate is fixedly mounted on the motor rotation shaft; a material through hole I is formed in the color conversion plate; a cutting component is mounted at the material through hole I in one surface, close to the motor, of the color conversion plate; a hot melting component is fixedly mounted on the cutting component; and an extruder device is mounted at a material through hole in the other surface of the color conversion plate and is fixed on the color conversion plate by virtue of a screw component II. The invention adopts a method for extruding the material by the extruder device and feeding the material into the hot melting device to be heated and melted, so that the material can be uniformly sprayed out; meanwhile, pressure is supplied for the material sprayed by a 3D printer nozzle; and when the printing color needs to be converted, the material is cut by the cutting component, and the rotary plate component is rotated and switched to the extruder device filled with the other material for further working.

Description

technical field [0001] The invention belongs to the technical field of 3D printer structures, and in particular relates to a color 3D printer material output device that can be used for multiple color conversion printing. Background technique [0002] 3D printing technology has been developed for more than 20 years. Since the early 1990s, domestic and international industries started almost simultaneously. In 2012, this technology received widespread attention at home and abroad, more from an article in the British "The Economist" magazine, which regarded 3D printing technology as one of the major symbols of the "third industrial revolution". The application object of 3D printer can be any industry, as long as these industries need models and prototypes. Israel's Objet believes that industries with high demand for 3D printers include government, aerospace and defense, medical equipment, high technology, education, and manufacturing.

AI Technical Summary

Problems solved by technology

When ordinary 3D printers "print" models, they only provide materials of one color, and cannot print out colorful models. The uniformity and stability of the product are poor, and it is unable to provide pressure power for the molten material ejected from the printer nozzle; in addition, the extruder used in the 3D printer is mainly used to extrude various rod-shaped materials , but in the existing material extruder, due to the reduction device driven by the motor, the power is too large or too small, so some material particles are often mixed unevenly and the extrusion volume is unstable.
