Igus iglidur J260-PF – tribofilament for 3D printing

Overview

• The best friction parameters among igus tribofilaments, ideal for low and medium loads.
• For larger parts, printing in an enclosed, heated chamber is recommended.

Key benefits

• Extremely low friction and long service life – printed bearings from J260-PF have demonstrated in tests comparable resistance to wear as injection-molded parts; igus tribofilaments achieve up to 50× lower wear than conventional printing materials.
• Long-term temperature resistance up to 120 °C (short-term up to 140 °C).
• Good resistance to liquids – also suitable for applications with contact with coolants and media.
• Self-lubricating composition – no need for additional lubrication throughout the entire service life.

Typical applications

• Plain bearings, bushings, sliding guides and guiding elements
• Gears (e.g. worm), cams, friction segments
• Prototypes and small series, especially in robotics and mechanical engineering.

Recommended print settings

• Nozzle temperature: 260–280 °C
• Bed temperature: 100–130 °C
• Chamber: heated recommended (without it, print rather smaller parts)
• Print speed: up to 20 mm/s for the best mechanical and tribological properties
• Bed adhesion: igus Adhesion Promoter recommended; for supports at higher temperatures consider high‑temp support (e.g. Formfutura Helios).

Variants and compatibility

• Diameter: 1,75 mm
• Weight: 750 g
• Color: yellow These variants ensure compatibility with a wide range of professional FFF/FDM printers.

Material properties (iglidur J260)

• Density approx. 1,35 g/cm³
• Coefficient of friction (dynamic against steel): 0,06–0,20
• Long-term service temperature: +120 °C, short-term +140 °C, lower −100 °C
• Hardness Shore D 77
• Moisture absorption (23 °C/50 % RH): 0,2 %
• Volume resistivity: >10¹² Ω·cm These values are based on the material data for iglidur J260 and help when designing functional bearing parts.

Notes for successful printing

• Thoroughly dry the material and limit part cooling (if possible, switch the fan off or to a minimum) for better interlayer adhesion.
• For demanding parts choose a smaller layer height and slower speed – you will improve the surface and dimensional accuracy.

Key features:

• Very low friction and exceptional wear resistance for moving parts.
• Identical tribological properties to injection-molded iglidur J260 – from prototype to series.
• Long-term temperature resistance up to 120 °C; also suitable for warmer environments.
• Good chemical/liquid resistance and self-lubrication – no additional lubrication.
• Optimized for bearings, bushings, gears and guiding applications.
• Requires higher printing temperatures and ideally a heated chamber for larger parts.
