3D-Fuel - Pro PCTG-GF10 Glass Fiber Filament - Midnight Black (1.75mm, 1kg)

Combine high-impact resistance with mechanical rigidity using 3D-Fuel Pro PCTG-GF10 in Midnight Black. Formulated with 10% glass fiber reinforcement, this industrial-grade filament builds on the natural advantages of PCTG—delivering up to 30x higher impact toughness, lower moisture absorption, and superior chemical resistance compared to standard PETG, all while eliminating thermal warping.

Reinforced with glass fibers for minimal shrinkage and flat printing, Pro PCTG-GF10 requires no heated enclosure and offers excellent layer adhesion. The 1kg spool is fully compatible with multi-material systems like the Bambu Lab AMS, making it a reliable solution for high-durability enclosures, drone components, living hinges, and automotive fixtures.

Key Features

• 10% Glass Fiber Reinforcement: Boosts tensile modulus and stiffness while eliminating thermal warping and lifting.
• Superior Impact Toughness: Modified with cyclohexane dimethanol (CHDM) for 20%–50% higher impact resistance than traditional PETG.
• Advanced Chemical Resistance: Resists cracking or degradation when exposed to alcohols, hydrocarbons, mild acids, industrial oils, and cleaning agents.
• Low Moisture Absorption: Absorbs significantly less water (0.1%–0.2% by weight) than PETG, leading to fewer print defects and easier storage.
• Bambu AMS Compatible: Ships on an AMS-ready spool vacuum-sealed with desiccant for seamless multi-material printing.
