COEX 3D Blueberry 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 has securely earned its spot as the second most popular 3D printing filament on the market. It delivers robust structural toughness comparable to ABS, but can be printed safely without requiring an enclosed build chamber or specialized fume filtration systems.
This is Blueberry PETG—a deep, vibrant blue that brings a clean, professional finish to both functional prototypes and final end-use assemblies. Proudly manufactured in our dedicated production facility located in Wisconsin, USA, COEX 3D filaments are formulated using 100% premium virgin resin and high-quality colorants with absolutely no cheap 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 across every spool, ensuring 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
