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 as a metal replacement for industrial 3D applications
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 unique 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.
Compared to stainless steel, 3D parts made of Infinam PEEK 9359 F are approximately 80 percent lighter and 30 percent tougher with excellent fatigue resistance. This combination of properties makes Evonik's new filament the preferred high-performance material as a metal replacement in demanding lightweight applications. Infinam PEEK 9359 F also boasts outstanding wear resistance and low sliding friction, making it ideal for manufacturing lightweight structural parts.
The 3D components printed from Infinam PEEK 9359 F can withstand long-lasting temperature effects of 250 ℃ or short-lasting temperature effects of over 300 ℃.
Filaments for industrial and medical 3D applications
"Following the commercial success of the PEEK filament for medical technology, we are now expanding the product range to include an industrial material grade," says Sylvia Monsheimer, who heads Additive Manufacturing & New 3D Technologies at Evonik. "We use our innovative strength in polymer chemistry to constantly develop and bring to the market new filaments, powders, or photopolymers to diversify the material landscape and thereby enable new infinite 3D applications."
Evonik is bundling its 3D printing expertise in its Additive Manufacturing Innovation Growth Field. The strategic focus here is on developing and manufacturing new high-performance materials for key 3D printing technologies. In this context, Evonik has organized its product range of ready-to-use materials under the new Infinam brand.
