COEX - Forest Green PCTG Prime Filament | High-Impact PETG Alternative

Forest Green PCTG Prime – High-Impact Engineering Copolyester

PCTG Prime represents the next evolution in copolyester filaments. While it prints as easily as standard PETG, PCTG offers a significant upgrade in impact strength, chemical resistance, and thermal stability. Engineered for demanding applications, Coex 3D’s PCTG Prime delivers industrial-grade toughness without the need for a heated chamber.

The Forest Green finish provides a deep, professional aesthetic with excellent optical clarity and a smooth surface finish, making it ideal for both functional mechanical parts and high-end visual prototypes.

The PCTG Advantage

• Unmatched Impact Resistance: Significantly higher ductility and toughness than standard PETG, preventing fractures under stress.
• Chemical & UV Stability: Excellent resistance to oils, greases, and solvents, with enhanced UV protection for long-term durability.
• Thermal Integrity: With a higher heat deflection temperature (up to 76°C / 169°F), parts maintain their shape in more demanding environments.
• Precision Made in the USA: Manufactured in Green Bay, WI, using premium virgin resins with a strict ±0.03mm diameter tolerance.

Recommended Print Settings

• Hotend Temperature: 250°C – 270°C
• Bed Temperature: 70°C – 80°C
• Enclosure: Not required (Low shrinkage and warping).
• Print Speed: 40–60 mm/s (Adjust for optimal clarity).

Industrial Applications

• Functional Jigs & Fixtures: Durable tools that withstand impact and chemical exposure on the factory floor.
• Mechanical Components: Gears, hinges, and brackets requiring high ductility.
• Automotive Parts: Components that need to survive engine bay temperatures and fluids.
• Protective Enclosures: High-clarity housings for electronics and mechanical assemblies.

Note: PCTG is a glycol-modified copolyester and does not contain Polycarbonate, making it easier to print while retaining high-impact properties.
