FDM 3D printing technology has been widely used in industrial and medical fields due to its easy operation and low cost. However, its printing materials such as PLA and ABS have limitations. In recent years, the rapid development of various new functional materials has greatly expanded the application range of FDM technology.

1. Classification of new functional materials

These new materials can be divided into three categories: first, high-strength engineering plastics, such as PEEK, PPSU, etc. Second, biomedical materials, such as biocompatible and degradable resins: third, smart multifunctional materials, such as shape memory alloys and self-healing materials.

With these materials, the application field of FDM technology can be extended to high-end fields such as aerospace manufacturing, personalized medicine and smart products.

2. Technical challenges

However, there are also many technical challenges in new material printing: it is difficult to optimize the printing parameters of the material itself, there are compatibility problems between the material and the printer, it is difficult to predict the performance and quality control of the molded part, and the cost of printing consumables is high.

3. The realization path

 In order to realize the wide application of functional materials, it is necessary for material enterprises, equipment manufacturers and users to carry out in-depth cooperation and research and development in material design, printing technology and equipment matching.In general, functional materials provide great opportunities for the development of FDM printing. We have reason to believe that through continuous research and development and technological innovation, FDM printing will shine and benefit more industries and human life.
