⚠️ Important Usage Notes
⚠️ Carbon Fiber Nozzle Wear Warning
Carbon fiber is abrasive and will quickly wear standard brass nozzles. For optimal and long-lasting printing experience, we strongly recommend using hardened steel (Hardened Steel) or ruby (Ruby) wear-resistant nozzles. If possible, consider using hardened steel extruder gears as well.
💡 Professional Usage Guide
🧴 1. Storage & Moisture Prevention
PLA-CF comes in vacuum packaging. Do not open the package before use to prevent moisture absorption. Excessive moisture will severely affect 3D printing quality. After use, promptly dry the filament and store it in a vacuum bag to prevent moisture.
🔥 2. Drying Process
If printing performance decreases, dry before printing at (40°C / > 4 hours) for optimal results. We recommend using a filament dryer for print-while-drying capability.
🧵 3. Filament Protection
PLA-CF filament has higher rigidity and should not be excessively bent. Avoid excessive bending in the feed tube to prevent filament breakage. Handle gently during feeding.
🔧 4. Nozzle & Gear Selection
Long-term use of PLA-CF may cause excessive wear on nozzles and extruder gears. We recommend using hardened steel or ruby nozzles, and if possible, hardened steel extruder gears to extend equipment lifespan.
📦 5. Shipping & Pickup Limits
Pickup package weight limit is 5 kg, with dimensions not exceeding 105 cm total. Single package limit is 4 spools of filament. For multiple items, please consult customer service for shipping compliance.

❓ Frequently Asked Questions
Q: What's the difference between PLA-CF and standard PLA?
A: The main differences are strength and appearance. PLA-CF enhances rigidity and bending strength by 50-100% through added short-cut carbon fiber, while providing a matte black surface that hides layer lines. Standard PLA, though fine in appearance, has lower strength and is prone to deformation.
Q: Why do I need hardened steel or ruby nozzles?
A: Because carbon fiber is abrasive and will quickly wear standard brass nozzles. Using hardened steel or ruby nozzles significantly extends nozzle lifespan and reduces long-term usage costs.
Q: Does PLA-CF need drying?
A: Yes. PLA-CF comes in vacuum packaging and should not be opened before use. If printing performance decreases, dry before printing at 40°C for over 4 hours. We recommend using a filament dryer for print-while-drying capability.
Q: What applications is PLA-CF suitable for?
A: PLA-CF is especially suitable for applications requiring high strength and precise fits, such as drone parts, automotive components, industrial structural parts, and precision models. Its matte black surface also makes it ideal for high-end model making.
Q: How fast should PLA-CF print?
A: Recommended print speed is < 200 mm/s. Due to carbon fiber addition, excessively fast speeds may reduce layer adhesion. For complex structures or fine details, reduce to 100-150 mm/s.
Q: Will PLA-CF filament break?
A: PLA-CF filament has higher rigidity and should not be excessively bent. Avoid excessive bending in the feed tube. Filament breakage usually results from excessive bending or excessive force during feeding.
Q: How can I tell if PLA-CF has absorbed moisture?
A: If printing shows increased layer lines, reduced layer adhesion, or rough surface, the filament likely has absorbed moisture. Perform drying treatment in this case.
Q: Can PLA-CF be used for food contact applications?
A: Not recommended. PLA-CF is primarily for industrial and functional applications and is not suitable for direct food contact.
