COEX 3D Stone Gray PETG is an industrial-grade co-polyester filament engineered to bridge the performance gap between the ease of use of PLA and the structural toughness of ABS. By combining mechanical durability, high impact resistance, and elevated thermal thresholds with straightforward printing mechanics, PETG has become the industry-standard choice for both rapid prototyping and functional end-use parts. It provides robust strength comparable to ABS, all without the need for an enclosed build chamber or complex fume management systems.
This is Stone Gray PETG—a sophisticated, neutral, and professional-grade gray that provides a modern, understated aesthetic for your functional parts. Whether you are producing mechanical brackets, industrial enclosures, or detailed engineering prototypes, this filament offers the perfect balance of visual neutrality and rugged mechanical performance. Proudly manufactured in our Wisconsin, USA facility, COEX 3D filaments are formulated using 100% premium virgin resin and high-quality colorants with absolutely no fillers. Utilizing industrial-grade extrusion equipment and real-time dual-axis laser measuring quality control, we guarantee a strict 1.75mm (±0.03mm) diameter specification for jam-free feeding and beautifully uniform layer lines.
Post-Processing Note: While PETG matches the structural durability of ABS, please note that it cannot be vapor-smoothed using acetone. It is naturally resistant to chemical solvents.
Key Features & Advantages
