About This

• Industrial-Grade Strength & Rigidity – Reinforced with 15% glass fiber, PET-GF offers outstanding mechanical stability and impact resistance, surpassing standard PET and even PET-CF in overall toughness and dimensional accuracy.
• UV & Weather Resistant for Outdoor Use – Built to withstand sunlight and environmental stress, PET-GF Black maintains both color and structural integrity over time, making it ideal for outdoor, automotive, and mechanical projects.
• Exceptional Post-Print Stability: While PET-GF finished parts feature low moisture absorption for superior dimensional stability and consistent mechanical performance in humid environments, the raw filament is sensitive to humidity before extrusion. To ensure a flawless surface finish and maximum layer adhesion, we strictly recommend using a filament dryer or dry box during the printing process.
• Enhanced Heat Resistance (Annealable) – Annealing your parts increases heat deflection temperature and stiffness, making PET-GF suitable for components that must perform under high temperatures and continuous mechanical load.
• Professional Matte Black Finish – The rich matte black surface hides layer lines and enhances printed detail, giving parts a refined, industrial-grade appearance suitable for prototypes, tools, or finished products.
