The strength of 3D printed PEEK can vary depending on the specific type of PEEK and the manufacturing process used. In general, PEEK is a high-performance thermoplastic known for its high strength and stiffness, making it a popular material for aerospace, automotive, and medical applications.
The tensile strength of 3D printed PEEK can range from around 10,000 to 14,000 psi. For comparison, the tensile strength of aluminum is around 45,000 psi and the tensile strength of steel is around 60,000 psi.
It’s worth noting that the strength of 3D printed PEEK can be affected by factors such as layer thickness, printing temperature, and post-processing techniques. Additionally, the strength of 3D printed PEEK can be improved by adding carbon fiber, glass fiber or other reinforcement materials.
In any case, 3D printed PEEK is considered as a strong and stiff material, comparable with some metals, and it is also lightweight, chemical and temperature resistance.
