Characteristics and challenges of PEEK materials
PEEK is a high-performance thermoplastic with excellent mechanical properties, chemical stability, and high temperature resistance. As a result, it is widely used in many demanding applications, such as aerospace, automotive, and medical. However, due to the high melting point of PEEK, it is prone to problems such as deformation and warpage during the printing process. In addition, in order to fully exploit the properties of PEEK, complex post-processing, such as heat treatment and machining, is often required. These post-processing steps not only increase production costs, but also limit the breadth of 3D printing technology in PEEK applications.
Technological breakthrough: PEEK stable and efficient sintering and high melting point powder 3D printing
Recently, a team of researchers and engineers has successfully developed a new type of PEEK stable and efficient sintering and high melting point powder 3D printing technology. The core of this technology is to achieve stable sintering and high performance of PEEK in the 3D printing process by optimizing printing parameters and material formulation.
First of all, the researchers carried out a special treatment on the PEEK powder. They have developed a new preparation method that gives PEEK powder higher purity and uniformity. This homogeneous powder allows for better filling of the printer’s nozzle and ensures that each layer is deposited accurately.
Second, the engineers optimized the printer’s hardware and software. They adjusted the temperature and printing speed of the printhead to accommodate the high melting point characteristics of PEEK. In addition, they have developed a new heating system that can locally heat parts during the printing process to prevent deformation and warping.
Finally, in order to further improve the performance of PEEK, a new heat treatment process has been introduced. This heat treatment process can be carried out at lower temperatures and does not require traditional machining steps. With this heat treatment, the properties of PEEK can be significantly improved, and the dimensional accuracy and surface quality of the parts can also be guaranteed.
