Spectrum PCTG GF10 Natural
10% Glass Fiber Reinforced | High Impact Resistance | No Pigment Purity | 0.5kg-1kg
Spectrum PCTG GF10 Natural is a state-of-the-art engineering filament that combines the superior chemical and impact properties of PCTG with the structural reinforcement of 10% glass fibers. The "Natural" version is unpigmented, offering a technical, semi-translucent look that allows for the inspection of internal structures and fiber orientation within the print.
This material is engineered for professional users who require exceptional stiffness and dimensional stability without sacrificing the legendary toughness of PCTG. It bridges the gap between traditional PETG-based materials and high-end industrial composites.
PCTG is a premium copolyester that offers up to 20 times the impact strength of standard PETG. By adding glass fiber, we provide a material that can withstand high mechanical loads while resisting shattering under sudden impact.
💪 Unmatched Toughness
Excellent impact resistance (Izod notched) compared to PETG, even with the rigid glass fiber reinforcement.
📏 Low Shrinkage & Warping
The glass fiber inclusion drastically reduces the thermal expansion coefficient, enabling the printing of large, flat structural parts.
🧪 Chemical & UV Resistance
Naturally resistant to a wide range of oils, greases, and fuels, making it an ideal candidate for automotive and shop-floor use.
🧊 Industrial Aesthetics
The Natural finish provides a professional, matte-translucent appearance that elegantly hides layer lines.
- Automotive under-the-hood structural brackets
- Custom industrial tooling, jigs, and fixtures
- Durable housings for outdoor electronic equipment
- Chemical-resistant laboratory components
- High-stress mechanical gears and pulleys
- Functional prototypes requiring high dimensional accuracy

* Hardware Advisory: Glass fiber inclusions are abrasive. You must use a hardened steel or ruby nozzle. Standard brass nozzles will wear out rapidly, leading to inconsistent extrusion. For best results, dry the filament at 60°C for 4 hours prior to printing.
