COEX 3D - White PCTG Prime

Take your structural prints to the next level. Coex 3D’s PCTG Prime is an advanced, glycol-modified copolyester filament engineered as a major evolutionary upgrade over standard PETG. By optimizing the polymer matrix without adding polycarbonate, PCTG Prime offers vastly superior impact strength, enhanced chemical resilience, and higher temperature stability—all while maintaining the hassle-free, easy-printing nature you expect from a copolyester.

Unparalleled Strength and Ductility

If you love the ease of printing PETG but need a material that can survive rough physical environments, PCTG is the perfect solution. It boasts a substantially higher impact strength and superior ductility compared to PETG. This allows finished components to endure bending, high shock load, and structural mechanical stress without fracturing or shattering.

Superior Chemical, Thermal, & UV Resistance

• Harsh Environment Defense: Naturally immune to a broad spectrum of aggressive chemicals, including industrial oils, greases, and common workshop solvents.
• Elevated Thermal Stability: Features an improved Heat Deflection Temperature (HDT) capable of withstanding temperatures up to 76°C (169°F) before softening, ensuring your parts hold up under heavier thermal demands.
• Upgraded Weathering: Offers increased UV resistance compared to traditional PETG, making it more resilient against environmental degradation over time.

Effortless Workflow & Professional Finish

Despite delivering industrial-grade physical characteristics, PCTG Prime remains incredibly easy to print on almost any desktop 3D printer. It exhibits low shrinkage rates and exceptional dimensional stability, which virtually eliminates corner warping. Because it does not require a heated build chamber, it is accessible to hobbyists and enterprise print farms alike, laying down cleanly with a beautiful, high-clarity surface finish.

Key Features

• Exceptional Impact Strength: Creates tough, rugged structural parts that resist shattering under sudden loads.
• Precision Manufacturing: Held to rigorous dimensional standards with a strict diameter tolerance of ±0.03mm for highly uniform extrusion paths.
• Premium Resins: Extruded using only premium, 100% virgin raw resins to guarantee material purity and eliminate print artifacts.
• Proudly Made in the USA: Formulated, manufactured, and quality-tested right in Green Bay, Wisconsin.

Ideal Engineering Applications

• Functional mechanical prototypes and end-use parts
• Industrial jigs, alignment fixtures, and manufacturing tooling
• Under-hood or interior automotive components
• Protective structural casings, electronics enclosures, and durable covers
• Chemical-resistant containers, bins, and lab organizers
