Abstract

The invention discloses a 3D printing melt extrusion shower nozzle, which comprises a printing head, a driving roller, a driven roller, a heater and a motor, wherein the motor is in transmission connection with the driving roller; an extruding space allowing printing materials to enter is formed between the driving roller and the driven roller; the printing head comprises a main body part provided with a cylindrical cavity, a cone-shaped part connected to the bottom end of the main body part and provided with a cone-shaped cavity, and an ejecting part connected to the bottom end of the cone-shaped part and provided with a cylindrical cavity; and the heater is arranged at the outer side of the main body part in a winding manner. The 3D printing melt extrusion shower nozzle has the advantages that the ejecting part provided with the cylindrical cavity is arranged at a nozzle of the printing head, so that the control precision is high; through the arrangement of a temperature sensor, the temperature of a heating cavity can be controlled in real time, so that the materials can be evenly extruded; and an extruding spring is arranged between the driven roller and printing materials, so that the friction force between the printing materials and the driven roller can be controlled, and the control precision is improved.

Description

technical field [0001] The application belongs to the technical field of 3D printing, and in particular relates to a 3D printing melt extrusion nozzle. Background technique [0002] 3D printing has become an emerging manufacturing technology with industrial revolution significance. With the continuous development of 3D printing technology, high precision and desktop will become an important direction of 3D printing equipment. [0003] In the 3D printing nozzle in the prior art, the position between the driving roller and the driven roller is fixed. If the diameter of the printing material changes, the frictional force will change, resulting in deviations in printing accuracy. [0004] Different printing materials require different temperature ranges for the heating chamber of the print head. Only when the temperature of the heating chamber is kept at a temperature where the material is just in a molten state can the material be ejected evenly. Contents of the invention ...
