Background
Additive manufacturing (Additive Manufacturing, AM) commonly called 3D printing, which is a manufacturing technology for manufacturing solid objects by integrating computer-aided design, material processing and forming technology and stacking special metal materials, nonmetal materials and medical biological materials layer by layer in the modes of extrusion, sintering, melting, photo-curing, spraying and the like through a software and numerical control system based on digital model files. Compared with the traditional processing modes of wire removal, cutting and assembly, the method is a manufacturing method of accumulating materials from top to bottom, and the method is free from existence. This makes it possible to manufacture complex structural members that would otherwise be prohibitively expensive to manufacture. Additive manufacturing is of great interest because of its discrete-pile-up principle, the feature of directly manufacturing parts driven by three-dimensional data of the parts.

The extrusion pressure is easy to adjust, so the application range is wide, however, the preparation method generally needs to heat the polymer material to a certain degree, and the operation flow is long.
Therefore, there is a need for a method for producing a wire rod for additive manufacturing, which does not require heating and softening a polymer material in advance by a heating device and has a short operation flow.

In the present invention, the shape of the metal material is preferably spherical or nearly spherical. The invention avoids the adverse effect on the viscosity of the raw materials due to the fact that the non-spherical material has lower filling density and higher inter-particle friction force by selecting the spherical or near-spherical metal material.
In the present invention, the metal material is preferably a cermet powder. In the present invention, the particle size of the cermet powder is preferably 20 to 60. Mu.m, more preferably 30 to 50. Mu.m. According to the invention, the metal ceramic powder is selected as the wire rod formula, and the grain size is limited in the range, so that the tensile strength, the yield strength and the elongation of the wire rod can be improved.
The sources of the nonmetallic materials and the metallic materials are not specially specified, and the nonmetallic materials and the metallic materials can be prepared conventionally or can be commercially available products.
In the present invention, the volume ratio of the nonmetallic material to the metallic material is preferably (1 to 5): (6 to 8), more preferably (2 to 4): (6-8). The invention limits the dosage of the nonmetallic material and the metallic material in the above range, which is favorable for obtaining the wire rod with high density, high tensile strength, high yield strength and high elongation.
The mixing device is not particularly limited in the present invention, and a mixing device known to those skilled in the art may be used. The mixing time is not particularly limited and can be conventionally set.
In the present invention, the continuous extrusion is preferably performed in a continuous extruder. The continuous extrusion machine is not particularly limited in the present invention, and a conventional continuous extrusion machine may be used.
The continuous extrusion is preferably subjected to a preheating treatment in the present invention. In the present invention, the temperature of the preheating treatment is preferably 130 to 170 ℃, more preferably 140 to 160 ℃. In the present invention, the holding time of the preheating treatment is preferably 100 to 150 minutes, more preferably 110 to 140 minutes.

In the present invention, the rotation speed of the continuous extrusion machine is preferably 30 to 50rpm, more preferably 35 to 45rpm. The invention limits the rotation speed of continuous extrusion to the above range, which is beneficial to melting the polymer in the nonmetallic material by utilizing a large amount of heat generated by friction force existing in the continuous extrusion process, so that the polymer is wrapped around the metallic material, thereby being beneficial to obtaining the wire for additive manufacturing with better performance.
After the continuous extrusion is finished, the present invention preferably cools the continuously extruded product. The cooling method of the present invention is not particularly limited, and may be any cooling method known to those skilled in the art.

As can be seen from fig. 1, the raw materials are uniformly mixed in a V-type powder mixer, conveyed into a groove of a continuous extrusion wheel, and the mixed powder is brought into a boot groove of a extrusion female die in the rotation motion of a roller; and then under the action of friction force, the polymer powder in the female die is crushed, rubbed, melted and wrapped with metal powder, and the wire is formed by cooling after passing through the female die.
