Abstract

The invention relates to a 3D (three-dimensional) printer spray head for printing monomers material and composite materials. The 3D printer nozzle comprises a reinforced phase feeding mechanism, a monomer material feeding mechanism, a discharging mechanism, a stirring device, a heat sink, an electromagnetic valve control device and a nozzle, wherein the reinforced phase feeding mechanism comprisesa reinforced phase cavity, an organic solvent cavity, a feed roller, a drive motor, blades and a heater; the monomer material feeding mechanism comprises a stirring drive motor, a monomer material cavity and stirring rods; and the discharging mechanism comprises a rotating motor, a mixing and stirring chamber, a heater and a temperature sensor. When the monomer material is printed, the monomer material is uniformly stirred in the cavity and then reaches the nozzle by way of the mixing and stirring chamber to be sprayed out; and when the composite material is printed, a reinforced phase and the monomer material enter the mixing and stirring chamber together for secondary uniform stirring, and the mixed material is sprayed out by the same nozzle. The 3D printer spray head can not only printdifferent kinds of monomer materials, but also can print the composite materials; and the materials can be uniformly mixed by stirring, and thus, the spray head can be effectively prevented from being blocked.

Description

technical field [0001] The invention relates to a nozzle structure of a 3D printer for additive manufacturing. Background technique [0002] With the continuous advancement of science and technology, 3D printing technology is in rapid development and is constantly being used in aviation, industry, automobile and medical related fields. A 3D printer is a machine for rapidly prototyping products. It generates mathematical model files by modeling the product, and uses bondable materials such as powdered metal or plastic resin to print and form layers by layer-by-layer printing and layer-by-layer accumulation. Compared with the traditional technology, it not only saves materials, but also greatly improves the molding efficiency. At present, as a key component, the nozzle of a 3D printer is constantly being studied for improvement. The nozzle of the 3D printer is fixed on the frame, and the nozzle can be controlled to move and print parts in three-dimensional space. Most of ...
