Evonik launches PEEK-based filament for extrusion 3D printing technology

Evonik announced the launch of a new PEEK-based filament suitable for extrusion-based 3D printing technologies.

INFINAM PEEK 9359 F is a high temperature and chemical resistant material that is said to be suitable for the additive manufacturing of sophisticated industrial plastic parts. It follows the launch of the medical PEEK 3D printing filament VESTAKEEP i4 3DF for medical implants in May 2020.

In order to be able to offer PEEK to its industrial customers, Evonik has launched the natural-colored INFINAM PEEK 9359, which has a diameter of 1.75 mm and is wound on 500G spools. It is characterized by high mechanical strength, hydrolysis resistance and inherent flame retardancy and is therefore considered suitable for 3D printing of light and high-performance components in industries such as aerospace, automotive, and oil and gas.

Evonik suggests PEEK as a metal replacement material because, according to the company, it is around 80% lighter than stainless steel, 30% tougher and has excellent fatigue resistance. The material should also have excellent wear resistance and low sliding friction, which makes it ideal for lightweight components. Parts printed with the material can withstand long-term temperature effects of 250 ° C or short-term temperature effects of over 300 ° C.

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