Abstract

The invention discloses a nozzle for a 3D printing machine, which is used for realizing fine adjustment of the size and the spraying direction of a consumable material sprayed from the 3D printing machine. The printing nozzle comprises a material feeding pipeline (13), wherein the tail end of the pipeline is provided with an outlet, a control mechanism (16) for changing the size and the direction of the nozzle is arranged in the pipeline, can be actuators (16) distributed at the periphery of the nozzle, and also can be the combination of a blockage material (27) arranged at the inner side of the nozzle and the actuators (16) arranged at the periphery, and the actuators and the blockage material are both made of an electrostrictive material or a magnetostrictive material. According to the nozzle, the size of the sprayed material can be changed in real time according to the requirement of the 3D printing, and meanwhile, the spraying direction also can be finely adjusted.

Description

technical field [0001] The invention relates to a spray head of a 3D printer with controllable diameter, which is applied to 3D printing equipment. Background technique [0002] 3D printing technology is a kind of rapid prototyping technology. Based on a digital model file, it builds an object by printing it layer by layer using bondable materials such as powdered metal or plastic. In recent years, 3D printing has gradually been used in the direct manufacture of some products, and there are already parts manufactured using 3D printing technology. This technology finds application in industries such as industrial design, automotive, aerospace, and the medical industry. [0003] 3D printing equipment prints printing materials on the working platform through nozzles. When printing fine structures, nozzles with smaller diameters are required, while nozzles with larger diameters are required when printing larger areas. At the same time, when printing some structures, the fine ...
