As one of the leading specialty chemicals companies with operations in more than 100 different countries around the world, Evonik knows a thing or two when it comes to 3D printing materials. Last year, the company developed and launched a PEEK or polyetheretherketone filament for FDM 3D printing of medical implants. The latest PEEK 3D printing material was announced this week. The filament, introduced under the brand name INFINAM® PEEK 9359 F, is intended for industrial 3D printing applications with the most common extrusion-based technologies (FFF / FDM).
“After the commercial success of the PEEK filament for medical technology, we are now expanding the product range to include an industrial material quality. We use our innovative strength in polymer chemistry to constantly develop new filaments, powders or photopolymers and bring them to market in order to diversify the material landscape and thus enable new, infinite 3D applications, ”says Sylvia Monsheimer, Head of Additive Manufacturing & New 3D Technologies at Evonik, stated in a press release.
The new ready-to-use INFINAM® PEEK 9359 F high-performance material from Evonik is a chemical and high temperature resistant polymer and appears to be a good choice for 3D printing industrial plastic parts instead of using metal material. PEEK is quite a fascinating material: in addition to medical applications, the thermoplastic is widely used in the manufacture of sophisticated automotive and aerospace components due to its high strength and continuous operating temperatures, low flame smoke and toxicity, and excellent thermal stability and chemical inertia.
“INFINAM® PEEK 9359 F is a high-performance PEEK filament in industrial quality that is easy to process in FFF (FDM) printers. Due to its unique properties, it is suitable for the aerospace, transport, oil and gas, etc., for the production of light and high-performance parts, ”says the Evonik website.
INFINAM® PEEK 9359 F has a natural color with a diameter of 1.75mm and is wound on 500g spools that can be used in most standard FFF and FDM 3D printers for PEEK materials. The polymer has many interesting properties: In addition to what has already been mentioned, it has hydrolysis resistance or inherent flame retardancy as well as high mechanical strength, high wear and fatigue resistance and low sliding friction. Parts that were 3D printed with this material should be able to withstand short-term temperature effects of over 300 ° C or long-term temperature effects of 250 ° C. According to Evonik’s website, the material’s unique crystallization provides much better adhesion between vertical layers and better wave transmission performance than metal.
With regard to metal, Evonik says that parts 3D printed with the new INFINAM® PEEK 9359 F weigh around 80% less and are 30% harder than equivalent parts made from stainless steel. With all of these properties combined, the material should be well suited to 3D printing lightweight, high-performance parts for demanding applications, such as the automotive, aerospace, and oil and gas industries, which are typically made of metal.
Evonik’s innovation growth area for additive manufacturing focuses on the development and manufacture of new high-performance 3D printing materials. For this reason, the company has organized its range of ready-to-use AM materials here under the new INFINAM® brand.
