From production to packaging, strict quality control of products and materials, verification and confirmation of key processes, personnel and workshop management, eSUNMed maintains rigorous quality management to ensure strict control of process quality throughout the entire production process, ensuring product quality and efficient production.

3. Processing and Applications of Medical PEEK 3D Printing Filaments

As a new high-strength engineering plastic, Polyether Ether Ketone (PEEK) has excellent properties, including high-temperature resistance, self-lubrication, and chemical stability. PEEK materials also offer outstanding biocompatibility, and when compared to metal materials, PEEK materials have a modulus of elasticity that closely matches human bones. This mechanical performance meets the normal requirements of the human body, making it an ideal material for orthopedic implants. It can be used for manufacturing medical implants such as support structures, link plates, sternal fixation belts, and intervertebral fusion devices.

In the application of PEEK in cranial repair, its advantages compared to traditional titanium materials include:

1.Biocompatibility: PEEK materials have good biocompatibility, reducing the body’s rejection response to implanted materials and lowering the risk of postoperative complications.

2.Modulus of Elasticity: PEEK’s modulus of elasticity is close to that of human bones, enabling better biomechanical adaptation to surrounding bone and reducing potential stress-related problems.

3.Lightweight: PEEK materials are relatively lightweight, reducing the burden on the implant site and aiding patient recovery.

4.Formability: PEEK materials have excellent formability, enabling customized design to suit individual patient needs and adapt to different cranial defect shapes.

5.X-ray Transparency: PEEK material exhibits excellent transparency to X-rays, allowing doctors to perform post-operative imaging checks to ensure the success of the surgery.

6.Corrosion Resistance: PEEK materials have strongly resist chemical corrosion, reducing postoperative degradation and damage to materials.

Traditional processing methods for PEEK materials include mechanical cutting, which has drawbacks such as thin bone plates, large shape radii, high costs, and material waste. Due to its high precision and freedom, additive manufacturing technology allows for both macro and microstructural customization of medical implants, ensuring better biomechanical compatibility with the patient’s defect site and meeting clinical personalized treatment needs. 3D printing technology to customize models for PEEK-related applications can achieve rapid manufacturing, complex structural design, cost savings, increased efficiency, reduced production time, and material consumption.

Currently, eSUNMed ‘s medical-grade PEEK 3D printer is also under testing.

The professional and mature development of eSUNMed’s medical 3D printing filaments production line will further promote the application of additive manufacturing technology in the medical field. A diverse range of medical 3D printing materials will provide more possibilities for personalized medicine. In the future, eSUNMed will continue to develop more medical 3D printing materials with excellent performance, such as PCL, PLGA, TPU, and more. Stay tuned!
