Plastik Core PC-CF 1.75mm Black SAMPLE 100g

Product detailed description

PC-CF is a composite material that combines the extreme heat resistance of polycarbonate with the enormous rigidity of carbon fibers. The addition of carbon eliminates the biggest disadvantage of pure PC - its tendency to warp. Carbon fibers act as an "internal skeleton" that stabilizes the print, increases its dimensional accuracy and gives it a luxurious matte appearance.
Key features
• Extreme stiffness and strength: Significantly higher tensile and bending strength compared to pure PC or nylon.
• Excellent dimensional stability: Thanks to carbon, the material has minimal shrinkage, which allows the printing of large and technically precise parts.
• High temperature resistance: Withstands temperatures up to 110 - 140 °C (depending on load), making it ideal for use near engines and machinery.
• Matte finish: Carbon fibers mask the transitions between layers, resulting in a professional, aesthetic finish.
• Low weight: Carbon reduces the overall density of the material while maintaining above-standard strength.
Recommended printing settings
• Nozzle temperature: 260 - 290 °C.
• Bed temperature: 100 - 120 °C.
• Need for a hardened nozzle: Carbon fibers are highly abrasive. A regular brass nozzle can be destroyed after just a few hours of printing. We recommend a nozzle made of hardened steel (Hardened Steel) or with a ruby ​​tip (diameter min. 0.4 mm).
• Closed chamber: Although it warps less than pure PC, a stable ambient temperature is crucial for large parts.

Suitable applications
1. Drones and robotics: Frames, arms and components where low weight and maximum rigidity are required.
2. Motorsports: Air intakes, sensor mounts and functional components under the hood.
3. Industrial fixtures: Templates and fixtures that must not change shape under pressure or heat.
Pro Tip: Carbon fibers are prone to breaking at extremely sharp bends in the feeder. Make sure the filament path from the spool to the extruder is as straight as possible.
