Four difficulties in the development of metal 3D printing

First of all, although 3D printing is a technology of free structure manufacturing, many processing methods are required to avoid the problems of post-processing of 3D printing. It is necessary to use the CNC machine tool processing technology of the traditional manufacturing industry to solve the shortcomings in the post-processing process of 3D printing.

Second, due to support problems in metal printing, later parts cannot be processed. Because 3D printing adopts the technology of layering materials, during the production process, some parts may be deformed due to gravity, so supporting materials are needed. After the inner cavity and other parts of some complex components are formed with these support materials, the support materials are not easy to remove.

An important problem that metal 3D printing needs to solve.

Third, you need to be familiar with the material. There are many kinds of metal materials, and different materials have different properties and different application ranges. Take 3D printing aerospace parts as an example. The metal parts used in aerospace are all used in extreme environments. They have the characteristics of strong corrosion resistance, high temperature resistance, and high metal strength. If you are not familiar with the characteristics of materials, you will not be able to do them well. geographical advantage

Fourth, the high cost of metal 3D printing materials restricts the popularization of this technology. There are two main reasons for the high cost. On the one hand, most of the domestic metal 3D printing materials rely on imports; However, developing dedicated metal 3D

Printing raw materials is an inevitable requirement to promote the development of metal 3D printing, and it is also an inevitable trend to improve the 3D printing industry chain.
