PEEK filament for industrial 3D printing

Explore Evonik's INFINAM® PEEK 9359 F filament for industrial 3D printing of high temperature resistent lightweight parts using FFF or FDM technologies.

What are PEEK thermoplastics?

PEEK, or Polyether Ether Ketone, is a high-performance thermoplastic polymer that boasts excellent mechanical properties, including high temperature resistance, chemical resistance, and wear resistance. These properties make it an ideal material for use in demanding applications, such as aerospace, automotive, oil and gas, or medical devices to manufacture lightweight and high temperature resistent 3D parts.

PEEK filament for industrial 3D printing

Our PEEK filament is specifically designed for use with extrusion-based 3D printing technology, such as FFF or FDM. The filament is carefully manufactured to ensure consistent diameter and excellent print quality, allowing for precise and reliable printing results.

One of the unique benefits of PEEK filament is its high temperature resistance, making it suitable for printing parts that need to withstand extreme heat. With a glass transition temperature of a152°C, PEEK can withstand long term temperatures up to 250°C  or short term temperature up to 300°C, allowing for the creation of parts that can be used in harsh environments.

In addition to its high temperature resistance, PEEK filament is also highly resistant to most organic and inorganic chemicals and only dissolves in concentrated sulfuric acid and nitric acid, making it a great choice for applications that involve exposure to corrosive substances. Its excellent wear resistance also makes it ideal for use in high-stress applications.

INFINAM® PEEK 9359 F - Filament for lightweight parts

Fused filament fabrication (FFF) of high-temperature, aerospace-grade thermoplastics like PEEK has made significant progress in recent years and has become an established process for 3D-printing of complex parts. 3D printed parts made of PEEK exhibit outstanding properties like: 

  • excellent performance in heat resistance and chemical resistance
  • good warpage resistance
  • Inherently flame retardant with low smoke and toxicity
  • Resistant to gamma radiation, 250C steam and hydrolysis
  • excellent wave transmission performance than metal does

Our PEEK filament provides an unique crystallization which gives significantly improved adhesion between layers in the vertical direction. Compared to 3D printed stainless-steel parts, PEEK-based 3D printed objects are 80% lighter in weight and 30% tougher with excellent fatigue resistance making applicable as substitution to 3D printing metal. Due to superior wear resistance and low sliding friction of PEEK lightweight structural parts can be manufactured easily. 

Delivery of INFINAM® PEEK 9359 F

INFINAM® PEEK 9359F has the nominal diameter of 1.75 mm (+/- 0.04 mm*) and fit for FDM/FFF printing. It is supplied on spools with different volumes. The weight of 250 g, 500 g, 1 kg and 2 kg are available. Customer can choose the appropriate volume according to their parts or printing capacity.
The spools are packaged in vacuumed plastic bags to avoid moisture taken.
