Thermoplastic pellets for filaments extrusion

Arkema’s 3D printing solutions include a dedicated range of advanced polymers for filament extrusion printing technologies.

These products are designed for 3D printing highly technical parts requiring extreme performance.

Properties include resistance to high temperatures and harsh chemicals, and outstanding flame and smoke properties. These products enable the production of parts that will be used in some of the most demanding applications in the world and can bring high value to end-users.

Kepstan® PEKK

Kepstan® PEKK (PolyEtherKetoneKetone) is an extreme performance thermoplastic with a highly stable chemical backbone. Its tunable semicrystalline structure offers an outstanding combination of mechanical and thermal strength together with tremendous chemical, and fire resistance.

Kepstan® PEKK grades for filament extrusion offer both ease of printability and the highest physical performance of any thermoplastic material currently available for 3D printing.

Kynar® PVDF

Kynar® PVDF (Polyvinylidene fluoride) resins are extremely resistant to harsh chemicals and UV radiation. They are known to be among the most durable polymers in the world. This tough semi-crystalline fluoropolymer, formulatedfor printability, benefits from outstanding Z direction strength and ductility.

Filaments made from Kynar® resins are particularly suitable for early stage prototyping or short run manufacturing. Kynar® PVDF resins are specified for printing chemical processing equipment, fluid transport parts, outdoor exposed elements, or fixtures.

Pebax® TPE

Polyether block amide copolymers are highly regarded for their lightness, unmatched energy return, and cold temperature durability. This unique polymer offers the highly desirable combination of toughness traditionally associated with polyamides and the flexibility/elasticity more often seen with polyethers/polyesters.

Filaments made from Pebax® resin are particularly well suited for functional prototypes or short run manufacturing. Pebax® elastomers are world renowned in sports, industrial, and footwear applications.

Semi-crystalline Kepstan® PEKK Seals via Fused Filament Fabrication on the miniFactory Ultra® 

Arkema and miniFactory have collaborated to develop materials and processes for 3D printing functional objects in semi-crystalline Kepstan® PEKK.  In this white paper, we will present the equipment, method, and results.

  • Additive Manufacturing of very demanding applications: low capital cost and efficient use of materials
  • Additively Manufactured Semi-crystalline PEKK vs conventional PEKK seals: performance and mechanical properties comparison
  • The outcome: High quality and a reproductive result of mechanical properties of AM PEKK with miniFactory Ultra 3D Printer.
