Speed Versus Strength Comparison
print speed
Polymaker High Speed PETG Filament supports printing speeds of up to 500mm/s. Its enhanced fluidity allows for rapid melting and smooth extrusion, making it ideal for fast production of everyday models and large projects. In contrast, Polymaker Fiberon Carbon Fiber PETG recommends a maximum speed of 300mm/s. The carbon fiber reinforcement increases viscosity, requiring more careful calibration to maintain quality at higher velocities. If your workflow prioritizes rapid turnaround and high-volume output, the standard High Speed PETG offers a significant advantage in throughput.
material strength
Polymaker Fiberon PETG-rCF08 contains 8% recycled carbon fiber, which improves rigidity and structural strength compared to standard PETG. This composite material is specifically designed for functional parts like brackets, housings, jigs, and fixtures that require enhanced durability. Polymaker High Speed PETG focuses on toughness and impact resistance, offering good mechanical stress handling without the added stiffness of fiber reinforcement. For applications demanding high rigidity and dimensional stability under load, the Fiberon model provides superior structural performance due to its composite composition.
surface finish
Polymaker Fiberon Carbon Fiber PETG produces a clean matte surface finish. The carbon fiber texture helps reduce the visibility of layer lines, resulting in a professional appearance suitable for functional parts that also need to look refined. Polymaker High Speed PETG features a smooth and refined texture with a consistent appearance, creating a polished look typical of high-quality plastic prints. While both offer excellent aesthetics, the Fiberon variant provides a distinct matte finish that better conceals printing artifacts, whereas the High Speed version offers a smoother, glossier standard plastic look.
nozzle requirements
Polymaker Fiberon Carbon Fiber PETG is abrasive due to the 8% carbon fiber content. The manufacturer explicitly requires a hardened or wear-resistant nozzle to prevent damage during printing. Polymaker High Speed PETG does not list such restrictions, implying it is safe for standard brass nozzles commonly found on most desktop 3D printers. This difference is critical for your printer setup. If you are using a standard brass nozzle, the High Speed PETG is the only viable option without upgrading your hardware first.
spool weight
The Polymaker High Speed PETG Filament is available in a 1KG spool, providing more material per unit for standard projects. Polymaker Fiberon Carbon Fiber PETG is listed with a 0.5kg spool size in the primary data. A larger spool reduces the frequency of filament changes, which is beneficial for long prints or batch production. If you prefer fewer interruptions during printing or need more material for large-scale projects, the 1KG High Speed PETG offers greater convenience and value in terms of volume per spool.
Choose Your Polymaker Filament
Users needing fast, smooth prints
