COEX 3D Stealth Gray PETG is an industrial-grade co-polyester filament engineered to bridge the performance gap between PLA and ABS. Combining the mechanical durability, high impact resistance, and elevated thermal thresholds of engineering plastics with the straightforward printing mechanics of everyday materials, PETG is the ideal solution for both rapid prototyping and robust end-use parts. It provides structural toughness comparable to ABS, all without the need for an enclosed build chamber or complex fume management.
This is Stealth Gray PETG—a deep, sleek, and highly versatile dark gray that offers a professional, modern aesthetic for any project. Whether you are creating mechanical housings, low-profile fixtures, or functional hardware that needs to blend into a professional environment, this filament delivers a clean, high-quality finish. Proudly manufactured in our Wisconsin, USA facility, COEX 3D filaments are formulated using 100% premium virgin resin and high-quality colorants with zero cheap fillers. Utilizing industrial-grade extrusion equipment and laser-measuring quality control, we guarantee a strict 1.75mm (±0.03mm) diameter specification for consistent, jam-free performance.
Note: COEX 3D Stealth Gray PETG is a deep, solid-toned gray. It does not contain matte additives and maintains the signature high-strength characteristics of our premium PETG line.
Post-Processing Note: While PETG matches the structural durability of ABS, it cannot be vapor-smoothed using acetone. It is naturally resistant to chemical solvents.
