## Summary description

Spectrum S-Flex TPU+20CF is a high-performance flexible 3D printing filament reinforced with 20% carbon fiber. This composite material combines the elasticity of TPU with the structural rigidity and thermal resistance of carbon fiber. It is ideal for industrial applications requiring durable, flexible parts with a matte finish and high dimensional stability. Compatible with most FDM 3D printers.

## Long description

Spectrum S-Flex TPU+20CF is a high-performance 3D printing filament that combines the inherent elasticity of thermoplastic polyurethane with the structural reinforcement of 20% carbon fiber. This composite material is engineered to provide a unique balance between flexibility and mechanical rigidity, resulting in parts that are both resilient and dimensionally stable. The inclusion of carbon fiber not only enhances the tensile strength and thermal resistance of the printed objects but also provides a distinct matte finish and potential electrostatic discharge (ESD) properties, making it a versatile choice for demanding industrial environments.
Advantages
The primary advantage of this filament lies in its ability to maintain a Shore hardness of 90A while benefiting from the stiffness and durability of carbon fiber. This synergy allows for the production of flexible components that resist deformation and wear under stress. Furthermore, the material demonstrates excellent interlayer adhesion and chemical resistance, ensuring that printed parts remain durable even in challenging conditions. The carbon fiber reinforcement also contributes to improved thermal stability, allowing the material to perform reliably in environments where standard flexible filaments might fail.
Suitable for
Functional prototypes requiring flexibility and strength
Robotics components and soft grippers
Protective housings for electronics with ESD requirements
Automotive parts and gaskets
Sporting equipment components
Industrial tooling and jigs
When it may not be suitable
This filament is not recommended for applications requiring high transparency or extreme elongation, as the carbon fiber content significantly limits the stretchability compared to pure TPU. Additionally, due to the abrasive nature of carbon fibers, it is not suitable for use with standard brass nozzles, as they will wear out rapidly.
Key specifications
Diameter: 1.75mm
Material composition: TPU reinforced with 20% carbon fiber
Shore hardness: 90A
Density: 1.23 g/cm³
Thermal resistance: Up to 134°C
VICAT softening point: 91°C
Net weight: 0.25kg
How to use
To achieve optimal results, ensure the filament is kept dry using a filament dryer, as TPU is hygroscopic. Use a hardened steel or ruby nozzle to prevent premature wear caused by the carbon fiber particles. Set your nozzle temperature between 210°C and 245°C and the heated bed between 45°C and 70°C. While a closed chamber is not strictly necessary, maintaining a stable environment helps ensure consistent quality. Print at a speed of 45-70 mm/s with the cooling fan set to 100% for the best surface finish and detail retention.
What to consider before purchase
Ensure your 3D printer is equipped with a hardened nozzle
Verify that your extruder is capable of handling flexible filaments
Consider the need for a filament drying solution
Check if your project requires ESD-safe materials
Usage recommendations: For the best results, always use a hardened nozzle and keep the filament in a dry environment. If you experience adhesion issues, you may use specialized adhesives like Dimafix or Magigoo to ensure the first layer stays secure during the printing process.
