LUVOCOM® 3F PEEK 9581 NT is based on polyetheretherketone (PEEK), one of the highest performing engineering thermoplastics in the world and can replace metals and composites. LUVOCOM® 3F PEEK 9581 NT is a material from LEHVOSS. LUVOCOM® 3F PEEK 9581 NT is an unreinforced grade and can be used for multiple applications in different industries; aerospace-, gas-, oil-, automotive- and the medical industry. This semi crystalline thermoplastic provides high temperatures, excellent mechanical and chemical resistance properties. The excellent layer adhesion of LUVOCOM® 3F PEEK 9581 NT improves the impact resistance, strength, durability and the printing process.

LUVOCOM® 3F PEEK 9581 NT features:

  • Outstanding temperature and chemical resistance
  • High strength, including z-layers
  • Flame retardant
  • Cytotoxicity proliferation according EN ISO 10993-1

Additional info:

Recommended temperature for heated bed is ≥110°C. Adhesion is possible on different surfaces. LUVOCOM® 3F PEEK 9581 NT can be used on desktop FDM or FFF technology 3D printers able to reach the required temperatures. Dry the spool before printing: 6-8 hours at max. 120°C or 4 hours at 130°C.
Note: brass nozzles are not allowed – this contains copper which is reactive with PEEK.


Cool and dry (15-25˚C) and away from UV light. This enhances the shelf life significantly.
