Multi-color packaging: Each roll is approximately 330m long, with a wire diameter of approximately 1.75mm. These 3D printing filament bundles offer a variety of colors to inspire your creativity and are the key to your printing projects. High-quality PETG filament - Made from high-quality PETG, a commonly used thermoplastic material with a low melting point, PETG is easy to use, resists warping and shrinking, is odorless during printing, and produces a smooth, glossy surface. Precise and consistent dimensions - Strict tolerances guarantee a 3D printing filament diameter of 1.75mm, with a dimensional accuracy of up to +/- 0.02mm, for smoother and more stable printing. Reduced tangling, easy to use - Fully mechanical winding and rigorous manual inspection ensure neat filament alignment, reducing tangles and potentially preventing breakage and damage. No clogging and bubbles - Designed and manufactured with superior interlayer bonding and excellent flowability, they enable smooth and stable extrusion.
