    Advanced material with carbon fiber used to make pieces of high mechanical strength and fireproof.

    The PEI CF (JNM 0803) is considered an advanced engineering thermoplastic containing ether linkages and imide groups in its polymer chain mixed with carbon fiber. Carbon fiber is a pseudo-amorphous material that offers the PEI a lower melting point, slower crystallization and maintains the high crystallization temperature (Tg=180ºC). This union also enhances the structural stability, improving the mechanical and printing properties. That's why the PEI CF has earned a place among one of the two most powerful and easy-to-use materials within 3D FDM / FFF printing. In addition, this material competes at a general level with the most widely used thermoplastics in the engineering industry (polysulfones, polyphenylene sulphides and polyketones).

    Relying on the vast experience and many years of research, the great French manufacturer Nanovia has obtained the PEI CF JNM 0803. The JMN 0803 behaves in a stable manner in all areas that allows its use in a 3D printer FDM. Next, the molecular structure of JNM 0803 is observed.

    The PEI CF filament presents all the qualities that an advanced material requires. The thermal resistance is one of the highest in the market, having a Vicat softening temperature (A50) higher than 215ºC and a maximum constant working temperature with a pressure of 0.45MPa of more than 200ºC. The main advantage, with respect to other materials (NylonStrong), is that at these temperatures the mechanical properties hardly change. This is because its great dimensional stability, improved thanks to carbon fiber, maintains the structural shape even when raising the temperature, something unthinkable with most existing materials in 3D printing FDM / FFF. These qualities are used to make short cycle injection molding tools, carbon fiber lamination tools and other types of molds that are subject to high pressure and temperature values (Autoclave). Within this type of high strength molds are those used for the vulcanization process of plastics, such as rubber. Thanks to PEI CF molds can be made faster, easier and cheaper than current steel molds.

    Another remarkable quality is the chemical resistance of this material to a large list of fluids: halogen hydrocarbons (benzene), automotive fluids (coolant), alcohol and aqueous solutions (sea water). This quality, together with its low density (1.26 g/cm3) and being a fireproof material, makes the PEI CF a very common material for making final parts of engine parts in the field of aeronautics and the automotive industry. liquids, oils and gases.

    Something very important when it comes to manufacturing parts for engineering is that it doesn't interfere or produce derivations of electric currents. The PEI with carbon fiber has a great dielectric stability (resistance to transforming an electrically insulating material into conductive), being able to manufacture insulating parts for electronic circuits or housings for electrical outlets. In particular, the application of this material in electronic circuits is ideal to ensure the operation, since the PEI CF is a material with a large capacity of heat dissipation and frequency.

    In the section of mechanical properties, the PEI CF stands out when gathering high values of resistance in all fields. The Young Module (Traction Module) of the PEI CF (4685 MPa) is superior to that of the technical materials of 3D printing by more than 45%; Nylon-Carbon Fiber CF15 (500 MPa), PC-Max (2048 MPa), Nylon PolyMide COPA (2223 MPa). The Flex Module PEI CF is 4950 MPa, clearly exceeding all conventional and technical 3D printing materials; Nylon PolyMide COPA (1667 MPa), ABS Premium (2000MPa), PC-Max (2044MPa). The rest of the mechanical properties can be consulted in the technical data sheet PEI CF available in the downloads section.

    To use the PEI CF you need a great experience in the sector of 3D printing and a 3D printer qualified for it, since it requires an extrusion temperature of 390ºC, a base temperature higher than 120ºC and a chamber temperature of 80ºC, that is why it is recommended to use industrial 3D printers such as 3NTR A2 or 3NTR A4 that meet all the requirements. To ensure a good adhesion to the printing base, it is recommended to use a PEI sheet to avoid the warping effect.


    During the printing of the desired parts with PEI CF internal stresses are generated, as in any type of plastic, which can be transformed into unwanted breaks or deformations. Eliminating these tensions is very simple and you only need a hot air oven and follow the following 5 steps:

    1º- Place the pieces in the oven at room temperature (20ºC).

    2º- Heat the oven at 150ºC for 1 hour.

    3º- Once spent 1 hour, raise the temperature to 200ºC and let one more hour pass.

    4º- Lower the temperature again at 150°C for 30 minutes.

    5º- Once the 30 minutes have passed, the oven is turned off and the pieces inside the oven are allowed to cool to room temperature.

    This process must be carried out by qualified personnel.
