3D printer filament Static Control TPU+20CF S-Flex black 0.25 kg (TPU+20CF-025-SPEC)

Static Control TPU+20CF S-Flex black is a flexible 3D printer filament supplied on a 0.25 kg spool. It is a thermoplastic polyurethane material reinforced with 20% short carbon fibers to increase stiffness and improve surface finish while preserving the elastomeric properties of TPU. The composite formulates a balance between flexibility and dimensional stability, making it suitable for FDM/FFF printers when parts require both resilience and enhanced mechanical performance.

Advantages

This TPU+20CF filament combines the elasticity of thermoplastic polyurethane with carbon-fiber reinforcement to deliver improved tensile stiffness, better wear resistance and reduced creep compared with standard TPU. The 20% carbon fiber content helps produce cleaner edges and a smoother surface appearance, while the material remains printable on common direct-drive and Bowden extruders within appropriate temperature ranges. The black coloration provides a uniform finish for functional parts and prototypes.

Suitable for

• Wearable components requiring flexibility and shape retention
• Gaskets, seals and vibration-damping parts
• Flexible housings and protective covers
• Functional prototypes with increased stiffness and reduced deformation
• Small structural parts where improved surface finish is desired

Key specifications

• Material: Thermoplastic polyurethane composite reinforced with 20% carbon fiber
• Color: Black
• Spool weight: 0.25 kg
• Compatibility: FDM/FFF 3D printers
• Mechanical properties: Increased stiffness and reduced creep compared to unfilled TPU

How to use

Load the filament onto an FDM/FFF printer following the manufacturer's guidance for flexible materials. Use an appropriate nozzle (hardened recommended for fiber-filled filaments) and set extrusion temperatures typically in the TPU range; specific temperature and speed should be adjusted according to your printer and slicer. Print at moderate speeds, enable retraction settings suitable for flexible filaments, and consider a direct-drive extruder for best feed reliability. Allow parts to cool gradually to minimize warping and post-process by trimming or light sanding if needed.

Usage recommendations

Store the spool in a dry environment and, if possible, in a sealed bag with desiccant to limit moisture uptake. Use a hardened steel nozzle to reduce wear from carbon fibers and calibrate extrusion flow before printing critical parts. Test small samples to fine-tune temperature, speed and retraction for consistent layer adhesion and surface quality.
