Structural and thermal performance of optimum 3D printed parts from continuous carbon fiber-Poly Ether Ether Ketone composites

Additive manufacturing, also called 3D printing, of composites can manufacture final parts with high strength and stiffness. In this project, carbon fiber composites with a high temperature polymer are used for 3D printing. A custom 3D printing head installed on a robotic arm is used for manufacturing. Specimens are 3D printed to evaluate structural and thermal properties of final parts. Automated manufacturing of composites using robotic 3D printing is efficient for fabricating small-scale parts with low volume and can open new opportunities for composites.

Carbon prepreg filaments for 3D printing high performance parts

There has been an extensive growth in additive manufacturing, 3D printing, over the past couple of years. At the moment, pure polymers are mainly used for manufacturing parts and they yield low strength and stiffness, not suitable for load-bearing products. The use of carbon fiber composites in 3D printing can significantly improve structural properties. Currently, there is no commercial 3D printing head capable of printing with carbon fiber prepreg filaments. A 3D printing head will be custom-built to accept these filaments and produce parts with high strength.
