Evonik has developed a new 3D printable filament based on PEEK (polyether ether ketone). The high-temperature and chemical-resistant ready-to-use material is particularly suitable for the additive manufacturing of demanding industrial plastic parts.

The high-performance polymer can be processed in common extrusion-based 3D printing technologies such as fused filament fabrication (FFF) or fused deposition modeling (FDM). Evonik is launching the new filament under the brand name INFINAM PEEK 9359 F.


INFINAM PEEK 9359 F high performance polymer is suitable for additive manufacturing of demanding industrial plastic parts.


With INFINAM PEEK 9359 F, Evonik now offers a new filament for industrial 3D applications. The natural-colored PEEK filament, which has a diameter of 1.75 mm, is wound on 500 g spools suitable for direct use in standard FFF/FDM 3D printers for PEEK materials.


Thanks to its properties such as high mechanical strength, hydrolysis resistance, or inherent flame retardancy, it is particularly suitable for the production of lightweight and high-performance 3D parts for the aerospace, automotive, and oil & gas industries.


As a metal replacement for industrial 3D applications


Compared to stainless steel, 3D parts made of INFINAM PEEK 9359 F are approximately 80% lighter and 30% tougher with very good fatigue resistance. This combination of properties makes Evonik's new filament the suitable material as a metal replacement in demanding lightweight applications.


INFINAM PEEK 9359 F is also with good wear resistance and low sliding friction. The 3D components printed from it can withstand long-lasting temperature effects of 250°C or short-lasting temperature effects of over 300°C.


“Following the commercial success of the PEEK filament for medical technology, we are now expanding the product range to include an industrial material grade,” said Sylvia Monsheimer, who heads Additive Manufacturing & New 3D Technologies at Evonik.
